This section describes the various inputs and outputs and provides guidance on how to

AX2550 Connections
The AX2550 uses a set of power wires (located on the back of the unit) and a DB15 con-
nector for all necessary connections. The diagram on the figure below shows a typical wir-
ing diagram of a mobile robot using the AX2550 controller.
The wires are used for connection to the batteries and motors and will typically carry large
current loads. Details on the controller’s power wiring can be found at “Connecting Power
and Motors to the Controller” on page 29
The DB15 connector is used for all low-voltage, low-current connections to the Radio,
Microcontroller, sensors and accessories. This section covers only the connections to sen-
sors and actuators.
For information on how to connect the R/C radio or the RS232 port, see “R/C Operation”
on page 109 and “Serial (RS-232) Controls and Operation” on page 131.
