Address on Ports 23 and 1001. Contact your network IT administrator for
assistance with these settings.
Set the Gateway Address to the required IP Address of the end-users Gateway. If
the end-user will always access the VSA-31-IP device from a computer connected
on the same network node, then the Gateway Address may be left at its default
value. Contact your network IT administrator for assistance with these settings.
Set the Net Mask to the required values compatible with the end-users network. If
the end-user will always access the VSA-31-IP device from a computer connected
on the same network node, then the Net Mask may be left at its default value.
Contact your network IT administrator for assistance with these settings.
3.2 Serial Configuration
At Power-Up, the VSA-31-IP makes a default connection from the RS-232-A port to
the RS-232-B port.
In this mode, all communication between the RS-232-A and RS-232-B port is
transmitted to the LAN connection on the VSA-31-IP units IP address, Port 1001.
No information transmitted from the LAN connection will be sent to the RS-232-A or
RS-232-B ports.
All communication through the LAN Port must occur at whatever baud rate, parity,
data bits and stop bit used by the RS-232-A and RS-232-B ports.
In order to communicate with the VSA-31-IP via the LAN, the unit must be
configured to operate at the same baud rate, parity, data bits and stop bit settings
being used by the devices connected to the RS-232-A and RS-232-B ports.
If you will not be communicating via the LAN to the VSA-31-IP unit, then the end-
user does not need to change anything.
The VSA-31-IP serial parameters may be altered by the following methods:
Use the Hall Research VSA-31-IP Software GUI
Use the Hall Research DS Manager to change the related parameters
Use a HyperTerminal TCP connection to the IP Address on the VSA-31-IP
using a Telnet connection to Port 23 using the appropriate commands.
The VSA-31-IP also has the ability to communicate bi-directionally from the LAN
port to the RS-232-A port or the LAN port to the RS-232-B port.
Any information transmitted to the unused RS-232 port is discarded.
To change the direction of the communication, the end-user is required to control 3
I/O lines via the VSA-31-IP IP Address Port 23.
In this mode, the end-user has a time limit of 3 minutes from the time the connection
is changed from the default RS-232-A to/from RS-232-B path. The time limit starts
whenever the VSA-31-IP units P1 line is set from “0” to “1”. If more than 3 minutes
is required to communicate on the LAN port, the end-user is responsible for toggling
the VSA-31-IP unit P1 line from “0” to “1” (if using Hall Research VSA-31-IP
Software GUI, this is done automatically) .
