SD Series Technical Manual

MDS 05-4846A01, Rev. F

3.0 TYPICAL APPLICATIONS

This section describes common scenarios the transceiver may be used
in. A number of variations are possible; If you have unique requirements
not found here, it is recommended that you consult a support specialist
at GE MDS. Contact information is provided at the back of this manual.

3.1 Operating Parameters

The transceiver can operate in both poll-response and “push” communi-
cation/report-by-exception networks. In poll-response networks a cen-
tral Master unit communicates with a number of Remote radios one at a
time. The Master exchanges data with the currently-connected Remote,
and when finished, it establishes a new connection with the next Remote
in the polling order. In push communication/Report by Exception net-
works, a Remote can also transmit if it has data to send, typically
prompted by a change in status conditions from connected data equip-
ment.

The radio includes a number of parameters which may be set to suit the
requirements of a particular application. Table 2 provides a summary of
common applications, protocols, and radio modes used. Refer to the
table to determine what applications can be supported and the required
radio settings.
