Attaching Cables
When attaching RS-422 (or RS-232) cables for controllers or for devices, refer to the sheet labeled
“AutoPatch Modula Connector Guide” that ships with the system. The sheet shows where to attach each
cable on the rear of each enclosure. Follow the sheet exactly; the system was programmed to operate
only
as indicated on the sheet.
The default configuration is for all controller equipment to be attached to X-Port connectors and
all device equipment to be attached to Y-Port connectors.
Important:
If using high data rates or long cable lines, see the “Termination Jumper” section
(page 142) before attaching cables.
To attach RS-422 (or RS-232) controllers or devices:
1.
Fasten the cables onto the X-Port or Y-Port DB-9 connectors (FIG. 94).
RS-422 Pinout for DB-9 Connector
The Modula RS-422 is designed to meet or exceed EIA-422A specifications and supports the
Sony
®
9-pin RS-422 pinout.
The DB-9 connectors on the boards each have transmit and receive pins which
must match
the DB-9
cable connectors from the controller and device equipment. The table below lists the functions for the
individual pin numbers for the board connectors for RS-422 and indicates the corresponding toggle
switch setting. If you know the pinout for the controller or device equipment, set the board connector’s
toggle switch (see page 141) to the setting that matches it (see table in FIG. 95 below), so that Transmit
is connected to Receive and Receive is connected to Transmit.
