Futaba T4PX Transmitter Radio System User Guide

T4PX SOFTWARE UPDATE
V1.4

T4PX Transmitter Radio System

After this software update, some of the T4PX features and functions described below may be altered. The instructions and information that follow are meant as a supplement to the original instruction manual that accompanied the T4PX transmitter. Please refer to the original instruction manual where applicable, but replace the steps indicated below with these instructions.
When copying model data onto another T4PX, make sure both radios are using the latest version of the software.

Compatibility with telemetry current sensor.

This product is compatible with our electric current sensor SBS-01C (sold separately). When the electric current sensor is mounted on the vehicle, the electric current, voltage and consumption capacity of the power battery, etc., can be displayed.
Refer to p.131 of the T4PX instruction manual for the telemetry screen display.
Before using the electric current sensor, it is necessary to register the sensor to the transmitter. Refer to p.138 of the T4PX instruction manual for how to register it.

The methods of setting alarm/ vibrator/limit are the same as for other sensors.
◆ Consumption capacity display
Unless the reset button of SBS-01C is pressed, the consumption capacity measured by SBS-01C is maintained and displayed as “integrated capacity” on the screen. If you wish to measure the consumption capacity for one run, it is possible to reset the consumption capacity display on the transmitter by the next operation. However, the record of the integrated capacity of the SBS-01C main body cannot be reset by the function which resets the transmitter display.

(Reset operation)
When you select “Reset” by (JOG), and press the (JOG) button, the consumption capacity display is reset to 0. The consumption capacity from the time of reset is displayed until you reset it again. If you reset the consumption capacity by pressing the reset button of SBS-01C, the consumption capacity display on the transmitter is also reset.

Caution: The reset operation on the transmitter resets the integrated capacity display on the T4PX. It does not reset the integrated capacity on the SBS-01C. The consumption capacity measurement range of SBS-01C is 32767 mAh maximum. When this value is exceeded, the consumption capacity display on the transmitter is also reset automatically. Depending on the timing, reset may occur during measurement. Therefore, make sure to reset the integrated capacity on the SBS-01C before the integrated capacity  display reaches 32767mAh.

Compatibility with non-Futaba sensors.

Refer to the sensor instruction manual for more information.

4. Steering mix, addition of mix rate function / expansion of steering angle adjustment range
A mix rate function was added to steering mixing. By using the mix rate, the motions of the servos on the left and right sides of the steering can be adjusted at the same time. In addition, the range of the steering angle adjustment function for each servo was expanded to 140 maximum. As regards the display on the steering mix screen, refer to p.84 of the T4PX instruction manual.

A channel limiter function which limits maximum servo movement was added. By superimposing mixing, the linkage can be protected by setting the limiter in case the servo motion becomes unexpectedly large. The channel limiter screen is displayed from the mixing menu. As regards the mixing menu display, refer to p.79 of the T4PX instruction manual.

◆ Mix rate adjustment
Select the “steering mix rate” using (JOG). Adjust each of the left/right steering angles using the (+) or (-) button, while turning the steering wheel hard-left or hard-right.
