Q5 SERIAL COMMUNICATIONS PORT WIRING
GENERAL NOTE
The information that is presented here and on the
following pages, refers to the Interface board and
not the Q5 board. The Interface board was devel-
oped to make customer connections to the pro-
cessor easier, as the Q5 use connections that are
too small and delicate to easily utilize in the field.
RS-232 WIRING AND JUMPERS
With the introduction of the Q5/Interface board,
customer connections to RS-232 have been elimi-
nated. If RS-232 communications IS required,
these signals may be converted to RS-422/485,
and the appropriate available port(s) utilized.
RS-422/485 WIRING AND JUMPERS
All four Interface board serial communications
ports are capable of RS-485, and COMM-1 (P10)
and COMM-2 (P11) can additionally be configred
as either RS-422 or RS-485.
The following table describes the Interface board
RS-422 connector pinouts and their associated
communications signals:

The following pictorial shows a cutaway view of
the Interface board, as well as the jumpers, LED’s
and signal pinouts to allow the end user to com-
municate to COMM-1 (P10) and COMM-2 (P11)
using RS-422/485 protocol, and to use COMM-3
(P16) to communicate via RS-485.
NOTE: COMM-
3 and COMM-4 do not have any associated
jumpers, and COMM-4 (P17) is reserved for I/O
board communications. Refer to the tables in
this section for the specifics on the jumper set
