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 enduser 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) .

Model VSA-31-IP

4. Operation

4.1 RS-232-A to/from RS-232-B with LAN Monitoring

At power-up, the VSA-31-IP unit defaults to a RS232-A to/from RS232-B path. Communication occurs without user intervention at whatever baud rate, parity, data bits and stop bits used by the devices connected to the RS-232-A and RS-232-B ports.

All communication along the RS-232-A and RS-232-B path is echoed to the IP Address of the VSA-31-IP on Port 1001. This communication can be monitored using a HyperTerminal TCP connection. The baud rate, parity, data bits and stop bits of the VSA-31-IP unit must match the settings of the devices communicating on the RS-232-A and RS-232-B ports.

The VSA-31-IP unit 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.

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.

Model VSA-31-IP

4.4 Software GUI

The VSA-31-IP Software GUI allows the end-user to monitor and control multiple VSA31-IP modules from one computer via a LAN connection.

The VSA-31-IP Software GUI has separate documentation describing its usage and operation. Refer to http://www.hallresearch.com/page/Products/VSA-31-IP documentation pertaining to the VSA-31-IP and the Software GUI.

The computer must be able to access the VSA-31-IP modules IP Address from the computer location the Software GUI is being executed on. If you can not ping the VSA31-IP modules IP Address then you will not be able to control or monitor the modules status.

The software GUI contains a list of the VSA-31-IP MAC and IP Addresses so that it can communicate with each module and ultimately control the devices connected to the RS232-A and RS-232-B ports.

Use the Hall Research DS Manager to configure each module that will be used in the system and make note of Each Units address MUST BE UNIQUE for proper LAN communication. The information for each VSA-31-IP module must be entered into the Software GUI so that device can be located via the network LAN.

The commands that will be sent to the RS232 devices are unique and must be entered correctly in order to get a specific response from that device. The following commands are required and must be supported by the devices connected to the VSA-31-IP module.

4.5 Access via Port 23 and Port 1001

A HyperTerminal TCP/IP connection can be used to access either PORT 23 or 1001.

 Port 1001 is used for the RS232 communication through the VSA-31-IP. All

communication occurs at the baud rate of the devices attached to the RS-232A and RS-232-B ports. The LAN connection Baud Rate must match the speed being used by the RS232 ports for meaningful communication to occur.

 Port 23 is used to change specific parameters in the VSA-31-IP module such

as its IP Address, Gateway Address, Baud Rate…etc.

To run a HyperTerminal window, open the application and set it up for TCP/IP connection on PORT 23 along with the VSA-31-IP IP address as the host address.

Commands to PORT 23 have the following format and replies:

STX Command/Reply CR

• STX character (ASCII code 0x02 or CTRL-B from the keyboard)

The unit will respond with the following codes indicating the status of the command requested. Anything other than ‘Accepted’ indicates a problem with that command/connection to the VSA-31-IP Module:

<^B>A means Accepted <^B>C means Error <^B>R means Rejected <^B>D means Denied <^B>F means Failed <^B>S means Bad Sequence

In the following table, the following notations are used:

Note on IP Settings via port 23

If you are unable to access the unit’s port 23 from your PC using the IP Modules default or last known IP address, it could be that the IP address of the IP Module is not compatible on your LAN. One way around this is to connect your PC directly to the IP Modules RJ45 port using a cross over cable, or use a switch or router not connected to anything else but your PC and the IP Module, and then configure your PC for a static IP address compatible with the current address of the IP Module. If the IP Module has the factory default of 192.168.123.199, a PC address of

192.168.123.nnn may be entered where nnn is any number except

199.

5. Troubleshooting

There are no field serviceable parts or circuits in the device. If you think that the device is malfunctioning, please verify the following:

 The LED’s are lit indicating that power is applied to the unit via the RS232-B

port or from an external power supply.

 You are using the correct RS232 cables for the devices that are attached to the

RS-232-A and RS-232-B ports. Using the wrong cable (e.g. … Using a straightthru cable when a null modem cable is required) will prevent the RS232 communication from working.

 When attempting to utilize the LAN connection, verify that you can get a

response when you ping the devices IP address. If you are unable to get a response from the VSA-31-IP via a ping, ensure that the computer you’re using is on the same network node as the VSA-31-IP. (For example, your computer IP address is 192.168.123.

192.168.123.150). Contact your IT Administrator for assistance.
