8.17. Ethernet Message Sending
The device can be used for sending a message to a certain IP:port address. The three different commands
allow controlling the connected (third-party)
8.17.1. Sending a TCP Message (ASCII-format)
The command is for sending a command message in ASCII-format. This method allows escaping the control
characters. For more information see the
Command and Response
ç CALL·/MEDIA/ETHERNET:tcpMessage(<IP_address>:<port_no>=<message>)
æ mO·/MEDIA/ETHERNET:tcpMessage
Example
ç CALL /MEDIA/ETHERNET:tcpMessage(192.168.0.103:6107=C00)
æ mO /MEDIA/ETHERNET:tcpMessage
The 'C00' message is sent to the indicated IP:port address.
Example with HEX codes
ç CALL /MEDIA/ETHERNET:tcpMessage(192.168.0.20:5555=C00\x0a\x0d)
æ mO /MEDIA/ETHERNET:tcpMessage
The 'C00' message with CrLf (Carriage return and Line feed) is sent to the indicated IP:port address. The
\x sequence indicates the HEXA code; see more information in the
8.17.2. Sending a TCP Text (ASCII-format)
