4.5 Access via Port 23 and Port 1001 or 6324
A HyperTerminal TCP/IP connection can be used to access either PORT 23 or
1001.
Either Port 1001 or 6324 is used for the RS232 communication
through the device. All communication occurs at the baud rate that
the device is currently configured for. The LAN connection Baud
Rate must match the speed being used by the RS232 ports for
meaningful communication to occur. Consult the product manual for
more information.
Port 23 can be used to change specific parameters in the device
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 device 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:
<^B> denotes the STX Character, 1 Byte of 0x02
denotes the CR Character, 1 Byte of 0x0D
Command Purpose Reply Notes
<^B>L Log Into Module <^B>A
<^B>O Log Out of
Module <^B>A
<^B>E Reboot Module None IP Connection
