RS-232 and RS-422 Cabling
007-4403-003 101
Proper pinouts for passing RS-422 input from Mini-Din connectors to DB-9 connectors
are described in the following tables. The Mini-Din connectors are those found on the
Menet board. The Menet board can be identified by its six serial ports and four Ethernet
ports. There are also notes for RJ12/16 and RJ45 connectors.
A proper adapter from Mini-Din to DB-9 uses the configuration shown in Table 7-4.
A proper adapter from DB-9 to RJ12/16 may be needed. For a Harris Automation
controller, Table 7-5 shows how this adapter should look.
