Service Mode – TCP Server Mode
In TCP Server Mode, Device Server is configured with a unique Port combination on
a TCP/IP network. In this case, device waits passively to be contacted by the
device. After the device establishes a connection with the serial device, it can then
proceed with data transmission. TCP Server mode also supports up to 5
simultaneous connections, so that multiple device can receive data from the same
serial device at the same time.
