number should be configured. In TCP Server mode, EG-SR-7100A provides
the unique IP address and port number on a TCP/IP network. EG-SR-7100A
waits to be contacted by the host computer, allowing the host computer to
establish a connection and get data from the serial device.
As illustrated in the figure, data transmission proceeds as follows:
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. In TCP Client mode, EG-SR-7100A can
actively establish a TCP connection to a host computer when serial data
arrives.
As illustrated in the figure, data transmission proceeds as follows:
1. EG-SR-7100A board operating as TCP Client Mode actively establishes a
connection based on the conditions set in the firmware. EG-SR-7100A can
connect to a remote host on start up, or connect later when data from serial
device arrives.
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.
