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
Pin 2 (TXD.OUT+)
Pin 3 (RXD.IN+)
Pin 14 (TXD.OUT-)
Pin 16 (RXD.IN-)
Channel 0 Setup:
Port
RS-232C
RS-422A
RS-423
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.
