Typical Applications; Operating Parameters - GE MDS SD Series Technical Manual

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" communication/report-by-
exception networks. In poll-response networks a central Master unit communicates with a num-
ber 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 networks, a Remote can also transmit if it
has data to send, typically prompted by a change in status conditions from connected data
equipment.
The radio includes a number of parameters which may be set to suit the requirements of a partic-
ular 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 mode settings.
