The contents of this section apply to the FLEX™ Roaming Decoder. Note that underlining
in the text indicates differences in specification from the FLEX™ Non-Roaming Decoder.
12.1
Its primary function is to process information received and demodulated from a FLEX radio
paging channel, select messages addressed to the paging device and communicate the message
information to the host. The FLEX decoder also operates the paging receiver in an efficient power
consumption mode and enables the host to operate in a low power mode when monitoring a single
channel for message information.
12.1.1
Additional Support: FLEX System Software from Motorola is a family of software components
for building world-class products incorporating messaging capabilities. FLEXstack™ Software is
specifically designed to support the FLEX
on a product’s host processor and takes care of communicating with the FLEX decoder , acquiring
