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-232-
A 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:
<^B> denotes the STX Character, 1 Byte of 0x02
