GEM-2M series User Manual

connected to serial port on GEMN-2M gateway. Therefore, users can access, control,
and manage serial devices through Internet (fixed line, or cellular network) no matter
where they are. There are four modes for virtual com connection: TCP Client, TCP
Server, UDP, and RFC2217.
TCP Client Mode
In TCP Client mode, GEM-2M can actively establish a TCP connection to a
pre-defined host computer when serial data arrives. After the data has been
transferred, GEM-2M can automatically disconnect from the host computer by using
the TCP alive check timeout or idle timeout settings.
1. Operation Mode:
Choose TCP Client.
2. Connection Control:
Choose “Always on” if you want to keep TCP connection
with TCP server all the time. Otherwise, you can choose “ON-Demand” if you
want to establish TCP connection only when data is required to transmit.
