PS-4C AND PS-4E: SERIAL PERIPHERAL
INTERFACE
IMPORTANT:
Before you proceed with cabling your serial peripherals to
the PS-4C or PS-4E, you must verify that the equipment supports either
EIA-232 or EIA-422 serial interface. In addition, you must know the
connector type and the pin/signal definitions for your equipment. If you
wish to connect a parallel printer to the PS-4C, you must use a Tran-x
SP-01 serial-to-parallel converter. You may also use Tran-x on the serial
ports of the PS-4E to connect a parallel printer located more than 25 feet
from the unit (up to 1000 feet).
Serial ports on the PS-4C and PS-4E have RJ-45 (8-wire) connectors
which accept RJ-11 (4-wire) or RJ-12 (6-wire) connectors.
Figure 9
and
Figure 10
on the following page are drawings of an RJ-45 receptacle and
plug. The pin/signal definition for each port is determined by the serial
interface you are using
.

If the serial ports of the PS-4C or PS-4E are set for EIA-232 serial
interface (default) and you will be connecting a device that uses
EIA-422 serial interface (e.g., Tran-x), you should reconfigure the
port for EIA-422 before connecting any cables. Please see
Section
4.4
.
NOTE:
Most serial printers, plotters, and modems use EIA-232
serial interface and do not have RJ-45/RJ-11 modular connectors.
Adapters are required to convert from DB-25 connectors to
modular connectors. BayTech has a complete line of adapters and
cables that will make your installation quick and trouble free.
