Controller Mounting
During motor operation, the controller will generate heat that must be evacuated. The pub-
lished amps rating can only be fully achieved if adequate cooling is provided. Good con-
duction cooling can be achieved by having the bot tom surface of the case making contact
with a metallic surface (chassis, cabinet).
Encoder Connection
Connection to the Encoders is done using a special connector on the front side of the
controller. The Encoder connector is a 6-pin Molex Microfit 3.0, ref. 43645.
Pin assignment are in Table 1, below.

Commands and I/O Connections
Connection to RC Radio, Microcomputer, Joystick and other low current sensors and actu-
ators is done via the 25 connector. The functions of many pins vary depending on control-
ler model and user configuration. Pin assignments are found in Table 2, below.
