Salcom UDP/TCP Test Tool
Salcom provides a simple tool for testing TCP/IP and UDP Ethernet connections. This can be
downloaded from the Salcom website under the 20-90 product page.
This tool may be used to:
Establish and test connections,
Send serial commands,
Initiate paging messages,
Monitor received messages.
Testing a connection
If the 20-90 is configured as a TCP server, the test tool should be a client.
Enter the 20-90’s IP address and port number in the “Remote IP Address and Port” fields.
Click “Connect”
Enter data to send in the bottom line and click “SEND”
Any returned data will appear in the Data Received box.
The command “SN?” will return the serial number and product information, and can be
used as a handy test command.
“CA1234560 1 Hello” can be used to initiate a paging message in Salcom protocol.
NOTE: To monitor received messages, the 20-90 must be configured to send received messages
out the Ethernet port. This can be configured on the System > General tab of Sacoto.
