2 TCP Server Function
In the Gateway mode the device is acting as a TCP server and transmits and receives data on the
TCP port that is defined with the CAN-Gateway Configurator. The default TCP port is 19228.
Connection:
• Server exclusively accepts a single connection.
• Additional connection requests are rejected.
• Server exchanges data and commands with the ASCII protocol.
The server receives Ethernet ASCII protocol messages, extracts the original CAN message and
transmits the CAN message to the selected CAN bus. Received CAN messages are packed into the
ASCII protocol and forwarded to the connected Ethernet TCP/IP client. The server also handles
commands.
The device automatically starts the protocol server after power-up. When a connection to the
server is closed or lost, the device is restarted and waiting for a new connection.
