- Page 14 1. The host connects to the EG-SR-7100A which is configured as TCP Server Mode. 2. As the connection is established, data can be transmitted in both directions - from the host to the EG-SR-7100A, and from the EG-SR-7100A to the host. TCP client mode Fig 2.5 TCP Client mode To operate this mode, Local IP, Subnet, gateway address, server IP, server port number should be set.
- Page 15 In this mode, EG-SR-7100A operates as TCP Server and waits for the connction request from the peer. If there is no connection and have data to be sent to the Ethernet, EG-SR-7100A changes to the client mode and send this data to the server IP.
