Wiring the 7-pin Serial Connector on SNAP-PAC-S2 Controllers
Each of the four serial ports on SNAP-PAC-S2 controllers uses a 7-pin pluggable connector supplied
with the controller (Eby part number EB1381M-07-500 or equivalent). Using the screws on the side
of the connector, insert or remove the wires as needed.
For a pinout of this connector, see
“SNAP-PAC-S2 Connectors, Indicators, and Pinouts” on page 55
.
CAUTION
: Do not use communication port connectors from a legacy OptoControl controller*. Legacy
connectors will fit in a SNAP-PAC-S2, but the pin orientation is different. Instead, use the connectors
supplied with the SNAP-PAC-S2 controller.
