Serial Port
The Serial Port tab configures which devices are connected
to the I/O hub. There are four I/O hub connections (RS232-1,
RS232-2, RS485-1, and RS485-2). For each connection, select
which device is connected (None, Control panel, GPS Data,

The optional UPS uses a 485 connection. When no addition-
al 485 connections are available, a 485 to 232 converter cable
can be used to connect to a 232 connection. Contact Safety
