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:
PLC-5 CH0 Quantum™ Com-2
Pin 2 (TXD.OUT+) Pin 1 (-RX)
Pin 3 (RXD.IN+) Pin 3 (-TX)
Pin 14 (TXD.OUT-) Pin 2 (+RX)
Pin 16 (RXD.IN-) Pin 4 (+TX)
Channel 0 Setup:
Port 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 (Master) for half-duplex or System
(Point-To-Point) for full-duplex
