Connecting the R/C Radio

Connect the R/C adapter cables to the controller on one side and to two or three channels on the R/C receiver on the other side. If present, the third channel is for activating the accessory outputs and is optional.

When operating the controller in “Separate” mode, the wire labelled Ch1 controls Motor1, and the wire labelled Ch2 controls Motor2.

When operating the controller in “Mixed” mode, Ch1 is used to set the robot’s speed and direction, while Ch2 is used for steering.

See “R/C Operation” on page 101 of the User’s Manual for a more complete discussion on R/C commands, calibration and other options.

Wire loop bringing power from controller to RC radio

FIGURE 4. R/C connector wiring for 3 channels and battery elimination (BEC)

This wiring - with the wire loop uncut - assumes that the R/C radio will be powered by the AX1500 controller. Other wiring options are described in “R/C Operation” on page 101 of the User’s Manual.

Important Warning

Do not connect a battery to the radio when the wire loop is uncut. The RC battery voltage will flow directly into the controller and cause permanent damage if its volt- age is higher than 5.5V.

Connecting the optional channel 3 will enable you to turn on and off the accessory output. See “Connecting Sensors and Actuators to Input/Outputs” on page 51 and “Activating the Accessory Outputs” on page 110 of the User’s Manual.
