Serial Output 1
This output is configurable via the software as either an RS232 or RS485 output. The LED will illuminate while
data is being transmitted. Follow standard RS232 or RS485 wiring when connecting these terminals.
2
Serial Output 2
This output is configurable via the software as either an RS232 or RS485 output. The LED will illuminate while
data is being transmitted. Follow standard RS232 or RS485 wiring when connecting these terminals.
3
IR Output
These terminals are provided for connection to IR repeaters. The LED above the terminals illuminate while the output
is active.
4
DIP Switches
DIP 1 changes the IR LED voltage output, ON = 5V Direct, OFF = 5V @20mA to standard IR LED. DIP 2 is not used
5
Output 1
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 1 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active.
6
Output 2
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 2 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active.
7
Output 3
This output provides a voltage free output with a normally open and normally closed contact. This is configured via
the software as the relay 3 output. (The maximum current rating of these contacts is 2A.) The LED above the
terminals illuminate while the output is active.
