7: Configuring and Using External Devices

Table 7-6 shows the pin assignments for an RS-422 serial port to an RJ-45 cable connector.

Notes:

• These pinouts are valid between an Origin system and a system not an Origin. For

peer-to-peer Origin communications, conﬁgure ports as RS-232 and use a standard

modem/null-modem cable. For peer-to-peer Sony communications,

straight-through cables are required. Hence, they both must be slave or both be

master.

• SGI P/N# 018-0650-001 6-inch Mini-Din 8 to DB-9 male adapter described in the

XIO MENET/MSER Board Installation Instructions cannot be used for RS-422

because pin 8 (RX+ on the Mini-Din 8 end) has no corresponding pin at the DB-9

end.
