Communications

This chapter contains information on how to set up the RLPC to
program and communicate with it.

DIP Switches

The DIP switches are behind a panel located between the RS232/485
IN port and the power connector. See Figure 4-1.

Figure 4-1 DIP Switch Cover

Remove the two Phillips head screws to expose the DIP switches.
