PLC-5/30 - Suggested Setup
Channel 0 - 25-pin D-shell serial port; supports
standard EIA RS-232C and RS-423 and is RS-422A
compatible.
NOTE: Channel 0 is optically-coupled (provides high
electrical noise immunity) and can be used with most
RS-422A equipment as long as:
•
Termination resistors are not used
•
The distance and transmission rate are
reduced to comply with RS-423
requirements
The PLC-5’s switch 2 is used to select RS-232C, RS-
422A, or RS-423. Channel 0 can be wired for RS-422.
Following is the pin connections showing how to wire
the PLC-5 channel 0 connector to the Quantum™ for
RS-422 communication:

Maximum Cable length
RS-232C
15 m (50 ft)
RS-422A
61 m (200 ft)
RS-423
61 m (200 ft)
Important guidelines:
•
When channel 0 is configured for RS-422A
compatibility, do not use terminating
resistors anywhere on the link.
•
When channel 0 is configured for RS-422A
(compatible) and RS-423, do not go beyond
61 m (200 ft). This distance restriction is
independent from the transmission rate.
Channel Configuration
Channel 0 = System (
