Scope
This application note provides information on how to use RS-232 communications to connect the
Encore Controller (both the SC and LC models) to various routers and peripheral equipment. All
RS-232 connections to the Controller are made through the controller’s DB-9 EXT COMM port.
Important
All Barco/ Folsom Routers can be connected to the
Encore Controller via Ethernet. This is the preferred
connection method.
EXT COMM Pinouts
The table below illustrates the pinouts on Encore’s EXT COMM serial connector.
Data “direction”
information is provided from the point of view of the Encore controller.

Cable Connection — Straight Through
The table below illustrates the required pin connections for typical Encore-to-Router configurations.
A straight-through RS-232 cable is used between Encore and the router.

Cable Connection — Null Modem
The table below illustrates the required pin connections for alternate Encore-to-Router
configurations (such as to Extron routers). A null modem RS-232 cable is used.

Lantronix Ethernet to Serial Cable Connection
Because Encore Controllers only have one RS-232 serial port (EXT COMM), an external device
(such as the Lantronix UDS200) is required for multiple RS-232 connections. The Lantronix
UDS200 connects to Encore via Ethernet, and provides two RS-232 ports.
The table below illustrates the pinouts on the UDS200’s serial connector.
