IP DUAL PORT CONTROLLER
4.2 RS-232-A to/from LAN
In order to command the VSA-31-IP unit to communicate on the RS-232-A to LAN
path, the VSA-31-IP unit must be told to create that connection path by configuring
the units P0 and P1 lines (if using Hall Research VSA-31-IP Software GUI, this is
done automatically).
Set “P0” to Low (0)
Set “P1” to High (1)
Set “P1” to Low (0)
Set “P1” to High (1)
The Status (RED) led will flash quickly and the 10/100 (GREEN) led will be ON.
The LAN and RS-232-A port will now communicate at whatever serial parameter
settings have been configured. Obviously, the device connected to the RS-232-A
port and the LAN must have the same settings for the communication to be
meaningful.
There is a 3 minute time limitation in this state before the VSA-31-IP unit will change
automatically to the default (RS-232-A to/from RS-232-B) path.
4.3 RS-232-B to/from LAN
In order to command the VSA-31-IP unit to communicate on the RS-232-B to LAN
path, the VSA-31-IP unit must be told to create that connection path by configuring
the units P0 and P1 lines (if using Hall Research VSA-31-IP Software GUI, this is
done automatically).
Set “P0” to Low (1)
Set “P1” to High (1)
Set “P1” to Low (0)
Set “P1” to High (1)
The 10/100 (GREEN) led will flash quickly and the Status (RED) led will be ON.
The LAN and RS-232-B port will now communicate at whatever serial parameter
settings have been configured. Obviously, the device connected to the RS-232-B
port and the LAN must have the same settings for the communication to be
meaningful.
There is a 3 minute time limitation in this state before the VSA-31-IP unit will change
automatically to the default (RS-232-A to/from RS-232-B) path.
