1. Introduction
1.1 General
The model VSA-31-IP is a member of Hall Research powerful RS232 product line. The
unit allows the user a flexible interface to perform the following functions:
•Monitor the RS232 communication between 2 serial devices from a remote
LAN connection
•Independently send and receive RS232 signals to separate serial devices from
a remote LAN connection at any speed
•Timeout feature - Default back to a standard communication path after 3
minutes to ensure that the 2 serial devices are always connected
•Detect connection to RS232-A port from a remote LAN connection without
disturbing the communication between RS232-A and RS232-B
When the VSA-31-IP is used to add IP capability to a classroom equipped with Hall
Research Switch-Cat® system, it is inserted in the RS-232 path between the VSA-31
Receiver and the Projector. It draws power from the VSA-31 Receiver and includes the
cable for connection to the VSA-31 Receiver.

2. Installation
2.1 Connecting the Unit
Refer to Figure 1 and 2 below for connector identification.
Connect the “RS232-A” and the “RS232-B” ports to the serial devices using
appropriate cables (for example, since the VSA-31 Receiver has a DB9 Male
connector, a Female/Female RS-232 NULL Modem cable should be used).
Connect the “LAN” port to a network Ethernet connection using standard CATx
cables (not supplied with unit)
Connect the “PWR” jack to the power supply (optional) or connect the unit to a Hall
Research compatible device capable of powering the unit via the RS232-B port
using the supplied RS232 Null Modem cable.

PWR connector: This is a standard 2.5mm plug connection. The unit’s power supply is
12-15 volts DC with a minimum rating of 250 mADC. Upon application of power from
the 2.5mm PWR connector or by the RS-232-B Pin 6, the 10/100 and Status LED’s will
either blink or become illuminated solid. Refer to Section 2.2 for a description of the LED
functions.
LAN connector: This is a standard RJ-45 Ethernet connection capable of be connected
to any 10/100 BaseT network.

3. Configuration
3.1 Ethernet Configuration
The Ethernet configuration of the VSA-31-IP must be correctly setup in order for the
end user to be able to communicate with the device across the network. Incorrect
configuration will result in the user not being able to communicate with the device.
The VSA-31-IP comes from the factory with a default configuration setup in the unit
as follows:
IP Address: ........................................................................192.168.123.199
Gateway:................................................................................192.168.123.1
Net Mask:...............................................................................255.255.255.0
If the configuration of the end users LAN is compatible with these default settings,
then the user is not required to make changes to the Ethernet Configuration.
If the configuration is not compatible, use the Hall Research DS Manager to change
the unit’s configuration.
Set the IP Address to any STATIC unused address available on the end-users
network. This IP Address of the VSA-31-IP must be in the same node as any
computer attempting to access the device. If the computer attempting to access the
device is on another network node, then the end-user is responsible for configuring
any network routers or switches necessary to allow access to the devices IP

IP DUAL PORT CONTROLLER
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) .
