3.13.2 Serial Gateway

Serial Gateway functionality is available for both RS-232 and RS-485 ports independently, and

enables serial data to be routed via the wired or wireless network connection. Serial Gateway

functionality is similar to radio modem functionality, allowing point-to-point and multipoint serial

data transfer.

Each WI-MOD-E serial port may be configured as Server, Client, or Multicast Group. When

configured as Server, the module will wait for a connection to be initiated by a remote client. When

configured as Client, the module will automatically attempt to connect to the specified remote

server. When configured as Multicast Group, the module will broadcast data to all members of the

same Multicast Group.

Some of the possible Serial Gateway topologies are illustrated below. As can be seen, it is possible

for serial data from a WI-MOD-E to be transferred to one or more WI-MOD-E serial ports, or to be

encapsulated within a TCP/IP socket for availability on an Ethernet network. Conversely, data

encapsulated in a TCP/IP socket can be reproduced at a WI-MOD-E serial port. Both WI-MOD-E

serial ports and the hard wired Ethernet port can be in use at the same time.
