32 GPOs and GPIs. The client is responsible for establishing and maintaining the
connection. In the event of a loss of connection, the client is responsible for re-
establishing the connection and re-configuring the GC-32, if required.
The GC-32 has two programmable operating modes. In Mode 1, all GPIs and GPOs are
allocated to the port 50001 connection and identified as GPI 1 to GPI 32, and GPO 1 to
GPO 32. In Mode 2, GPIs 1 – 16 and GPOs 1 – 16 are allocated to the port 50001
connection and GPIs 17 – 32 and GPOs 17 – 32 are allocated to the port 50002
connection. The operating mode of the GC-32 may be changed at any time. Changing
the operating mode will clear any pending GPI change of state notifications.
The GC-32 can be configured to accept a connection from any IP address on port 50001
or 50002. Or, it can be configured to accept a connection from only the specific IP
address for each port indicated on the GC-32’s Remote Device Assignment web page.
