The first five min-switches (A4 to A0) are used to specify the address of a Pinnacle
Plus+ unit (see Table 4-15 on page 4-52), which a host computer must include in the
message packet it sends. Each Pinnacle Plus+ supply in a network must have a unique
address.
The next two min-switches (BR1 and BR0) specify the baud rate for the AE Bus port
(see Table 4-15 on page 4-52). The last min-switch allows you to choose between RS-
232 or differential communication (RS-485 or RS-422). RS-232 is selected when the
switch is up. Differential communication is selected when the switch is down.
Note: You must remove the power supply cover to change between RS-422 and
RS-485.
