Chapter
he JR PCM9X is the latest JR transmitter and features the latest technology. New to the PCM9X range is the scroll bar interface.
Enter List Clear Timer Scroll Bar
The scroll bar is used in conjunction with the side entry buttons to provide a quick and efficient programming environment. Rotating the scroll bar left or right will move the highlighted (selected) section of the screen around available menu choices. Pressing the top of the scroll bar will activated the highlighted menu item and where appropriate, produce a sub menu. Within any sub menu, the highlighted menu item is similarly moved by rotating the scroll bar and selected by pressing the top of the scroll bar. On the lowest sub menu of any function, pressing the top of the scroll bar will toggle the choice when there are only two (e.g. ACT/INH) or bring up an entry box where there are more than two (e.g. when setting a travel adjustment figure). Within an entry box, rotating the scroll bar will increment or decrement the figure displayed, or rotate through the alternatives. Pressing the scroll bar completes the entry. To avoid accidentally pressing the scroll bar during rotation, it is best to rotate the bottom of the bar. When appropriate, block arrows on the screen point to any active side input buttons. To enter the main list of programmable functions of the transmitter please use the list button. To enter the last edited program function press the enter button. The clear button will return any currently edited value to default. The remaining button is used for timer applications, if enabled. The PCM-9X features digital trims on all controls and digital auxiliary trimmers at the top of the set. Digital trims allow the transmitter to independently remember trim positions for every model stored within the transmitter.

Battery Charging

The transmitter and receiver battery packs should be charged for at least 16 hours each evening before flying the next day. The first charge should last between 20 and 24 hours. Please note: the polarity of the JR charger is negative centre. This may be different to other manufacturers' chargers. You must make sure that the centre pin of your JR transmitter is always connected to negative to ensure correct polarity.

Charger

The charger supplied with your transmitter features two LED lights. These should always be lit when a battery is connected. If they are not lit make sure both the Tx and the Rx are turned off. During charging the charger will rise in temperature. This is completely normal and should not be a concern. If you have any worries or concerns about any of the charging equipment please seek expert advice. Please ensure the correct charge rate for your battery pack. Any battery over 1000mah should receive a charger rate of 120ma.

Control Stick Length

The stick units of JR radio equipment feature adjustable stick lengths. Please use the supplied allen key to make adjustments. Loosen the grub screw by turning the allen key counter clockwise. Then adjust the stick length to your required length. Lock the stick in place by turning the grub screw clockwise. Optional coloured sticks are available from your JR/MacGregor dealer, as well as long or short sticks.
Control Stick Tension Adjustment
Remove the RF module, NiCad battery and the back cover screws. Remove the transmitter back, being careful not to bend or damage the RF pins. The tension screws protrude from the back of the stick assemblies, immediately adjacent to the tension springs. Adjust each screw for the desired tension (anti-clockwise to loosen the stick feel, clockwise to tighten the feel).

DSC Cord

Direct Servo Connection (DSC) allows you to control the servos of the model without having to transmit any RF from the transmitter. The lead bypasses the module of the transmitter and allows safe operation of your radio equipment without interfering with any other pilots transmitted signals. To use the DSC connection make sure all equipment is turned off. Plug the DSC cable into the transmitter and then into the receivers charge lead. Then turn the receiver to ON. You do not need to turn the transmitter on as the DSC lead will automatically power up the transmitter. Turning on the transmitter will result in your set transmitting RF and possibly interfering with other modellers. Note: The DSC function will only operate with a JRC498D Deluxe Switch Harness, or the JRC498 Heavy Duty Switch. These switches include the orange signal wire, as well as the brown and red power wires.

Setting up your PCM9X

JR radio control systems include two main menus to program a model. The System menu is normally only accessed when first setting up a model and allows you to set basic parameters such as model type, modulation, stick mode etc. The Function menu allows you to alter parameters dependant upon model type (aeroplane, helicopter or glider) and allows quick access to set up, trimming and mixing facilities such as travel adjust, servo reversing and dual rates - and much, much more!

System Menu

To enter the System menu press and hold the enter key whilst simultaneously turning on the transmitter. From here you can choose the following functions:
Information Display Model Select Model Name Type Select Model Reset Modulation Transfer Trim Step Device Select Wing Type (Aero/Glider) Swashplate Type (Heli) Stick Mode

* Aero only

Fine tune the sensitivity of the digital trims New! Assign switches to suit personal preference Normal, Flaperon, Delta(*) and/or V-Tail Normal or 180o , 120o, 90o Select stick mode 1, 2, 3 or 4.

Model Select & Copy

The PCM9X transmitter employs a memory function, which memorises data for up to 20 individual aircraft. To avoid using incorrect model memories, it is recommended that you enter a unique name for each aircraft. Press the ENT key and turn the power switch ON to access the System Set-Up Mode. The Copy Function enables you to copy all of the settings of your current model to another memory (model number) within the same transmitter. This is very useful when setting up one aircraft several different ways.

Model Name

This function is used to input model names individually. Each models name is displayed in the normal screen automatically when that model is selected. To avoid confusing models, inputting model names is recommended. You can input a maximum of 8 characters for each model name. In the System Set-Up Mode, select the Model Name Function using the scroll bar. Once selected, press the scroll bar to access.

Type Select

The PCM9X is capable of performing as a helicopter, airplane or glider radio with full functions for each. It can also memorize data for 20 models individually. Note: If the power switch is turned OFF immediately after selecting the new model type, the change will not be saved. To change and save the model type use the scroll bat to select the GLID, ACRO or HELI. Press the scroll bar. At this time, existing model data is replaced by the model type aircraft data selected. Be sure to confirm the model name to prevent accidental loss of your important data. To cancel this function, return to former model type or turn the power switch OFF. Note: When you an alternative model type on this transmitter the allocation of lever switches, etc., will also change. Please refer to the appropriate section of this instruction manual for their functions. In the System Set-Up Mode, select the Type Select Function using the scroll bar. Once selected, press the scroll bar to access.

Data Reset

The Data Reset Function allows you to reset all the functions and settings for the current model to the factory pre-set conditions. Resetting does not affect the data already programmed for other models. Be sure to confirm that you need to reset the data of the currently indicated model in order to prevent accidental loss of valuable data. To access Data Reset, select Model Reset in System Set-Up and press the scroll bar.

Modulation

The Modulation Selection Function enables your PCM9X to transmit to all JR receiver types. You can select from either S-PCM or Z-PCM mode, depending on the Central Processing Unit within your receiver, or from PPM (Pulse Position ModulationFM). Caution: After making modulation changes, you must press the scroll bar to accept the new modulation type. If the Tx power switch is turned OFF before this procedure, the modulation change will not be saved.

Data Transfer

This function is used to transfer all existing memorised data for a model from one PCM9X transmitter to another PCM9X transmitter. Use the scroll bar to select the model to be transferred and activate by pressing the CLR key. To avoid the loss of important data, re-confirm model names when transferring. Caution: Please use special caution when copy function is activated as existing data is replaced with new data. Caution: When the battery alarm is activated (battery low), the copy function is not operational. Transfer Procedure 1. Select the model number to be transferred (transmitting mode side) through the model select function. 2. Both transmitters: With the power switches OFF, press and hold the ENT button while inserting the trainer cord into the DSC jack of the transmitter. 3. Both transmitters: Select the Transfer Function by rotating the scroll bar, then press the scroll bar to enter the Transfer Function.
4. Receiving mode transmitter (Tx to be programmed): Rotate the scroll bar to highlight the "Transmit" icon. Press the bar and the icon will change to "Receive". Rotate the scroll bar to highlight the Model Number icon. Press the bar and the icon will change to a box showing the available model numbers. Select the receiving model number by rotating and pressing the scroll bar. Next, press the CLR key to activate the receiving stand-by mode.

The PCM9X provides four types of Cyclic Collective Pitch Mixing (CCPM) mixing. Either normal mechanically mixed CCPM (mCCPM) or three types of electronically mixed CCPM (eCCPM). The three versions of eCCPM pre programmed in the software are 90 degree 4 servo, 120 degree 3 servo or 180 degree 2 servo.

Stick Mode

This function enables the stick mode to be changed between Mode 1, 2, 3 or 4.
Function Menu - Helicopter Dual Rates & Exponential
To enter the function menu, switch on the transmitter then press the enter key. From here you can choose the following functions:
Dual rates can be defined as the ability to vary the travel or throw rate of a servo from a switch. Due to differing travel rates, you will find that the sensitivity of the control either increases or decreases accordingly. A higher rate, or travel, yields a higher overall sensitivity. You may find it easier to think of the Dual Rate Function as double-rated or half-rates. The Dual Rate Function works in conjunction with the Exponential Function to allow you to precisely tailor your control throws. In Function Mode, use the scroll bar to select Dual Rate and access by pressing the scroll bar. Dual rates are available for the aileron, elevator and rudder channels of your R/C helicopter. The amount of travel is adjustable from 0-125%; exponential is adjustable from 0% (LIN) to 100% in 1% increments. The factory setting, or default value, for both the 0 and 1 switch positions is 100%. Either switch position may be selected as the low or high rate by placing the switch in the desired position and adjusting the value accordingly. There is also an automatic dual rate setting for all three channels, operable from the Flight Mode Switch.
You may also assign a dual rate setting to a flight mode. The PCM9X provides the user with 3 possible dual rate & exponential settings. These settings may then be assigned to a flight mode using the automatic switching function. When the Automatic Dual Rate (ADR) function is activated (ACT), when switching the Flight Mode switch to Stunt 1 and Stunt 2 the Aileron, Elevator,
and Rudder channel dual rate values will be switched between the settings available on screen for those flight modes. To activate ADR please enable the flight mode switch in the device select menu, and then set the D/R function to FM (Flight Mode). Typical dual rate settings are as follows: Dual Rate Switch Position 0 Position (reduced servo travel, for hovering e.g. 80% D/R, 20% EXP) 1 Position (maximum servo travel, for aerobatics e.g. 100% D/R, 10% EXP)

Reverse Switch

The PCM9X features a servo reverse function. This allows the user to electronically reverse the direction of a channel. Servo reversing is available for all 9 channels of the PCM9X. In Function Mode, use the scroll bar to select Reverse Switch and enter by pressing the scroll bar.

Sub Trim

The sub trim function allows you to individually fine tune the centring of all 9 channels on the PCM9X within a range of + or - 125% (+ or - 30 degrees servo travel). It is not a good idea to use excessive sub trim as you can eventually overrun the maximum travel of your servos. In Function Mode, use the scroll bar to select Sub Trim and access by pressing the scroll bar.

smooth, creating a more equal throttle servo movement during the entire throttle curve range.

Pitch Curve

Adjustment of the pitch curve is very similar to the throttle curve adjustment described in the preceding section. A thorough understanding of the throttle curve section will make pitch curve adjustment easier to understand. The PCM9X offers six (6) independent types of pitch curves: Normal, Stunt 1, Stunt 2, Stunt 3, Stunt 4 and Hold. Each pitch curve contains seven (7) adjustable points L, 1, 2, 3, 4,5 and H. Note: When setting pitch curve for throttle hold, it is necessary for the throttle hold to be active if this function is inhibited, the throttle hold pitch curve will not be visible on the screen.

Revolution Mixing

The Revolution Mixing Function mixes tail rotor input with the Throttle / Collective Function to counteract torque from the main rotor blades. When set-up correctly, the helicopter should climb and descend without a tendency to yaw in either direction. Because torque reaction varies with different power settings, it is necessary to vary the tail rotor pitch at the same time. The PCM9X offers two (2) separate revolution-mixing programs with independent up and down mixing for each one for flight mode position N and the other for Stunt 1, 2, 3 and Stunt 4 positions. The U, or Up, mixing adjusts the tail rotor compensation for the mid to high throttle/stick setting, and the D, or Down, mixing adjusts the tail rotor compensation for the mid to low throttle stick setting. Note: This function should not be used with a gyro in heading hold mode.
Setting Up Revolution Mixing First, adjust the helicopter so that it will hover in a neutral position with the tail rotor trim at centre. Next, establish the helicopter into a stable hover; then steadily increase the throttle to initiate a stable climb. The body of the helicopter will move in the opposite direction to the main rotor rotation. Increase the U, or Up, setting until the helicopter will climb with no tendency to turn or rotate. At a safe altitude, close the throttle and the helicopter will descend with the body turning in the same direction as the main rotor. Increase the D, or Down, mix until the helicopter descends with no tendency to turn or rotate. When attempting this procedure, throttle stick movements should be slow, and the initial acceleration and deceleration swings should be overlooked.

Gyro Sensitivity

The gyro sense software of the PCM9X allows the pilot to change the gyro gain remotely from the transmitter. The gyro can be controlled manually from the rudder dual rate switch or automatically with the flight mode switch. The rudder dual rate switch allows two gains to be chosen, while the auto function allows you to select three gains. The gain lead from the gyro should be connected to the AUX2 channel of the receiver.

Failsafe

The failsafe/hold function is only available with PCM modulation. If you have selected PPM modulation, the fail-safe screen will not appear.
Z-PCM modulation mode. All channels can be HOLD or can take a pre-selected position. Three fail-safe time delays are available. Select your chosen delay (0.2, 0.5 or 1.0 second) by using the scroll bar to select the desired setting. For a pre-selected position move the transmitter controls to the desired fail-safe position (throttle stick low!) and store the settings by pressing the CLEAR key. A beep will sound to confirm that the fail-safe positions have been stored. S-PCM modulation mode. All channels can be HOLD or individual channels can take a pre-selected position. The fail-safe time delay is fixed at 0.5 seconds. Use the scroll bar to select the desired setting as activate or inhibit. For each channel, move the appropriate control to the desired fail-safe position and store the setting by pressing the CLEAR key. A beep will sound to confirm that the fail-safe positions have been stored. Note: To check that the settings have been stored successfully, switch the transmitter off while leaving the receiver on. The servos should move to their pre-set fail-safe positions. We strongly recommend that you always select fail-safe for the throttle channel and set the throttle position to low.
Note: These preset positions remain stored in the transmitters model memory until data reset has been performed. Therefore, you do not have to reset the fail-safe each time you fly. Should you want to re-adjust the fail-safe presets, access the Fail-Safe Function and adjust the presets as you have just done. The transmitter automatically stores the settings for the last fail-safe adjustment.

Trainer

The PCM9x transmitter employs two separate types of trainer system - the normal trainer system where all functions are controlled by either the master transmitter or the slave and the programmable function trainer where one or more of the four primary control functions may be assigned to the slave individually. Basic Connections and Conditions for Training 1. The slave transmitter must be set to PPM (Pulse Position Modulation) and have a DSC (Direct Servo Controller) jack. The master transmitter may be PCM or PPM to suit its receiver. 2. Plug the trainer cord into each transmitters DSC jack. Note: Each transmitter will appear to be ON but neither is actually transmitting at the time. 3. Even though the slave transmitter is switched off, it must be fitted with a charged battery. 4. Switch the master transmitter ON. Do not switch on the slave transmitter; it is only necessary to have the master transmitter switched ON. 5. Push the trainer switch to transfer control to the slave. Release the switch and control automatically reverts to the master transmitter. Normal Trainer System In this mode, all functions are switched from the master to the slave using the trainer switch. No function setup is necessary to activate this system. Be sure the slave transmitters servo reversing, dual rates, end point adjustment and trims are identical to the master. This may be checked very easily by pulling the trainer switch. If the control surfaces move, adjust the slave transmitter until the trainer switch can be activated without a change to the control surface position.

Programmable Trainer Function (P.T.F.) In this mode, the master may assign functions one at a time to make learning to fly easier for the student. For example, the master may assign the slave rudder and elevator only. Thus, when the trainer switch is operated, the slave
has control of rudder and elevator only, while the master retains control of throttle and aileron. Releasing the trainer switch returns all control to the master transmitter. Be sure to reset the slave transmitter to its defaults by using the reset function. All servo reversing, pitch and throttle curves etc. will be taken from the master transmitter. Use the scroll bar to rotate around the channels and toggle between master and slave. Note that when all channels are set to master, the trainer system becomes NORNAL as indicated by the NORMAL T. on the screen.
The timer function provides an integrated timer for each model memory and a countdown timer too. The integrated timer shows the total time the transmitter has been turned on for that model, and the countdown timer is useful as a low fuel warning.
Both timers are displayed when returning to the main screen. The countdown timer is activated using either the bottom push button on the left hand side of the screen or the trainer switch. When the count down time is active, the transmitter will beep three times at 30 sec., twice at 20 sec., and beep once every second from 10 sec. to 0 sec. At zero there will be a continuous tone for 1 second and then the timer will begin counting up with a + indication to the left of the voltage display. When used as the stopwatch, the timer will count up to 59 min. 59 sec. and then re-start from zero.

Servo Monitor

The PCM9X provides a servo monitor function screen that allows you to see the actual real time travel of all 9 channels. This is a useful function to observe the effects of mixing on your channels. All trim and mixing adjustments are shown.
Throttle Cut & Trim Select
The PCM9X features an intelligent throttle trim as well as a throttle cut function. Only one or the other can be activated at a time. The throttle cut function turns the trainer switch into an engine kill switch.
Use the software to determine a point at which the engine will stop. When the switch is activated while at a low throttle setting the throttle servo will close to that point for as long as the switch is being held.
The trim select allows the throttle trim to remember a predetermined position. When a good idle point is found with the trim, enter the software and activate the trim memory. This allows the stopping of the engine with the throttle trim, but one click forwards on the trim will return the digital trim to the predetermined idle position.

The travel adjust range is from 0-150% (0 degrees to 60 degrees) from neutral and it can be adjusted for each direction individually. The factory default (data reset) value is 100% for each direction of servo travel.

Elevator to Flap Mix

Elevator to flap mixing is used to provide a quicker pitch response on the model. The general usage is to have up elevator/down flaps and down elevator/up flaps. The flap travel is independently adjustable for both directions.
Depending on the flight mode switch set-up in the device menu the mix can be activated using the Aileron, Elevator and Rudder dual rate switches, or the flight mode switch. The mix can also be activated using the throttle stick through the THRO STK function that defines an activation point on the throttle travel.

Aileron to Rudder Mix

Mixing aileron to rudder gives a more balanced turn by automatically giving the correct rudder action for a balanced turn.
Depending on the flight mode switch set-up in the device menu, the mix can be activated using the Aileron, Elevator and Rudder dual rate switches, or the flight mode switch. The mix can also be activated using the throttle stick using the THRO STK function which defines an activation point on the throttle travel.
The PCM9X provides a two (2) programmable throttle curves for aircraft. Typical uses for the throttle curves include: adjusting the curve to achieve a more linear throttle response; de-sensitising a particular part of the throttle stroke to maintain a more consistent throttle setting thats typical for rolling circles or torque rolls; or for giving reduced throttle range (high an low, which is useful for stall turns, etc.) in any selected flight mode or switch position. By setting the THRO STK point you can automatically change between curves at a set point.
To adjust points use the scroll bar to select a point and press it to activate the editing facility. Roll the bar left or right to decrease or increase the value. Press the bar again to set the value. Exponential Throttle Curve Function With the PCM9X system, individual throttle curves are selectable to be either straight (linear) or curved (exponential). To select an exponential curve, use the scroll bar to select and activate the exponential feature (an on will replace the off on the screen). With the exponential function ON, you will notice that any sharp angles of the throttle curve will become more rounded or smooth, creating a more equal throttle servo movement during the entire throttle curve range.

Standard Programmable Mixing (Mixers 3,4,5 and 6)
When activating the mix different mix values may be input for either switch position (position 0 or position 1). Separate, different (if required) mix percentages may be set for each side of neutral between 125% and 125%. Assigning Channels Using the scroll bar, move the cursor to the master channel. Press scroll bar down to activate selection. Roll the scroll bar to select the desired channel. Repeat this process to select the slave channel.
Assigning Mix Value Using the scroll bar position the cursor over POS0 and click. Move the master channel to highlight either the top or bottom figure. Increase or decrease the mix value by rolling the scroll bar. Use the CLR key to reset the mix value to zero. Complete the input by clicking the scroll bar. When activating the mix with a switch, different mix values may be input for both switch position 0 and switch position 1. Establishing Offset The purpose of the mixing offset is to redefine the neutral position of the slave channel. Any desired position may be set for the offset reference point. Position the cursor over Offset and click. Roll the scroll bar to input a value, in steps of 2, between 170 and +170. Operating with a switch Position the cursor over the required switch and click to enable that switch. The dark square moves to the top position (POS1) as a confirmation. More than one switch may be selected if required. Activation by Throttle Stick Position Click the scroll bar with THRO STK selected. Roll the scroll bar to select a throttle stick activation position between 0% and 100% or to inhibit (INH). Note that the stick resolution has 200 steps so that two clicks of the scroll bar are required to change the percentage displayed.
The failsafe/hold function is only available with PCM modulation. If you have selected PPM modulation, the fail-safe screen will not appear. Z-PCM modulation mode. All channels can be HOLD or can take a pre-selected position. Three fail-safe time delays are available. Select your chosen delay (0.2, 0.5 or 1.0 second) by using the scroll bar to select the desired setting. For a pre-selected position move the transmitter controls to the desired fail-safe position (throttle stick low!) and store the settings by pressing the CLEAR key. A beep will sound to confirm that the fail-safe positions have been stored. S-PCM modulation mode.

Programmable Trainer Function (P.T.F.) In this mode, the master may assign functions one at a time to make learning to fly easier for the student. For example, the master may assign the slave rudder and elevator only. Thus, when the trainer switch is operated, the slave has control of rudder and elevator only, while the master retains control of throttle and aileron. Releasing the trainer switch returns all control to the master transmitter. Be sure to reset the slave transmitter to its defaults by using the reset function. All servo reversing, pitch and throttle curves etc. will be taken from the master transmitter. Use the scroll bar to rotate around the channels and toggle between master and slave. Note that when all channels are set to master, the trainer system becomes NORNAL as indicated by the NORMAL T. on the screen.
Function Menu - Glider Dual Rates & Exponential
Dual rates can be defined as the ability to vary the travel or throw rate of a servo from a switch. Due to differing travel rates, you will find that the sensitivity of the control either increases or decreases accordingly. A higher rate, or travel, yields a higher overall sensitivity. You may find it easier to think of the Dual Rate Function as double-rated or half-rates. The Dual Rate Function works in conjunction with the Exponential Function to allow you to precisely tailor your control throws. In Function Mode, use the scroll bar to select Dual Rate and access by pressing the scroll bar. Dual rates are available for the aileron, elevator and rudder channels of your R/C glider. The amount of travel is adjustable from 0-125%; exponential is adjustable from 0% (LIN) to 100% in 1% increments. The factory setting, or default value, for both the 0 and 1 switch positions is 100%. Either switch position may be selected as the low or high rate by placing the switch in the desired position and adjusting the value accordingly. There is also an automatic dual rate setting for all three channels, operable from the Flight Mode Switch.
Typical dual rate settings are as follows: Dual Rate Switch Position 0 Position (reduced servo travel, for fast flight e.g. 80% D/R, 20% EXP) 1 Position (maximum servo travel, for slow flight e.g. 100% D/R, 10% EXP)
The purpose of Travel Adjust, also known as endpoint adjustment or adjustable travel volume, is to offer you precise servo control deflection in either direction of servo operation. The travel adjust range is from 0-150% (0 degrees to 60 degrees) from neutral and it can be adjusted for each direction individually. The factory default (data reset) value is 100% for each direction of servo travel.
The mix can be set to activate on numerous switched ranging from the flight mode switch to the timer switch.

Aileron to Flap Mix

This mix is only applicable when the dual flap function is activated in the wing type menu in the system menu. This function allows the flaps to work in conjunction with the ailerons to increase aileron control power.

S-PCM modulation mode.
