Superframes
The available RF Air time is divided into frames. A series of frames is assembled into a superframe
which can be used to sync multiple readers together. In some configurations, a series of superframes
is assembled into a megaframe which is used to sync multiple readers together. A frame can be either
a TDM or FDM period. A superframe can be a collection of TDM and/or FDM frames.
Multi-protocol RF Module Smart
The Multi-protocol RF Module Smart (MRFM-S) can handle multiple passive tag protocols; 6B (ISO
18000-6 Type B), 6C (ISO 18000-6 Type C), ATA (10374/ATA/AAR S-918) SeGo and Allegro,as well
as the active protocol IAG.
The MRFM-S design includes a software command for adjusting the transmitter peak output power.
When installing or replacing an MRFM-S, the lane must be retuned.
The MRFM-S transmits a message to the CGC. After the message is processed by the CTM, a
message is sent to the LC.
The signals between the MRFM-S and the DSM are shown in Table 4-1.
Table 4-1: MRFM-S signals to and from DSM
Signal
Description
data input from DSM
Tx DA  signals, RS422 bi-polar AM envelope modulation signals
data output to DSM
Rx DA  signals, RS422 bi-polar AM envelope demodulation signals
RF control
Rx EN  and Tx EN , RS422 bi-polar transceiver enable signals
RF control
A0  and A1 , RS422 bi-polar data address enable signals
power input from DSM

The serial communication settings for the LC COM port are configurable through the web interface.
Power Supply Module (PSM)
The PSM AC mains power requirement is 95-135VAC (60Hz+/-2 Hz) at 10A max input current.
The PSM is field replaceable and provides:
 A power switch and a 10A fuse
