link will be able to communicate using two TRP-C31S and the LAN.
Two TRP-C31S are configured with one setup as a TCP or UDP client and the other to TCP/UDP
server. When setting up the Server, the Remote IP address section must contain the address of
the Client. This will allow the Client’s IP address to pass the IP address-filtering feature of the
Server. Conversely, the Remote IP address of the Client must contain the Server’s IP address.
9-4 Heart Beat
The TRP-C31S provides a convenient way to establish reliable communications between two
devices. Communication port 5300 is reserved for the Heartbeat Protocol. Without this feature a
device that loses a connection and stops communicating would not be able to reconnect without
personally attending to the problem. A TCP data connection can be lost when there is a power
failure or temporary loss of an Ethernet connection on either the client or server.
If a loss occurs the Heart Beat feature will try to reconnect the TCP data connection every 5
seconds until communications is established again. The Heart Beat feature is available to use
with the Virtual COM Mode, Paired Mode and Direct IP Mode. This is not available when using a
UDP application.
