Chapter 2: Overview
2.3.3 Paired Mode
Paired Mode is also called serial tunneling. In this mode, any two serial devices that can communicate with a serial link will be able to communicate using two Serial Servers and the LAN.
Two Serial Servers are connected to a network, one configured as a TCP or UDP client and the other as a 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
2.3.4 Heartbeat
The Heartbeat protocol connection provides a reliable communications connection in Virtual COM Port Mode or with Paired Connection Mode. This feature restores the connection if communications are temporarily lost at either end because of loss of power or Ethernet connection.
Without this feature, a device that loses a connection and stops communicating would not be able to reconnect without human intervention. 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 Heartbeat feature will try to reconnect the TCP data connection every five seconds until communications are established again. The Heartbeat feature is available for use in Virtual COM Port Mode and Paired Connection Mode. This is not available when using a UDP application.
