Ip Polling Of Two Serial Ports On One Remote - GE MDS SD Series Technical Manual

In this example, the Host Computer is connected directly to the radio's
Ethernet port and the RTUs at the Remote sites are connected to the
transceiver via the radio's serial data ports. The IP Payload fea-
COM2
ture, used at the Master, efficiently passes TCP/UDP payload over the
air, and eliminates the need for an external terminal server. ( may
COM1
also be used for payload data if properly configured via the menu
system. See next example.)

IP Polling of Two Serial Ports on One Remote

In some cases, it is necessary to poll more than one RTU at a Remote
site. Figure 10 shows an example of such a system. Here, two RTUs are
connected to each Remote transceiver, both using the radio's serial
ports— and .

functions with a connected PC, but it may be configured for data service
using the web interface. This arrangement allows two telemetry net-
works to share a single radio system.
