parameters to the primary and secondary CFM, manages the OBU Account Status file, and keeps log

files for OBU transactions, system events, and trouble reports.

For a description of the ethernet interface protocol and file formats exchanged between a Lane

Controller and a Reader, refer to ICD 360450-112.

Channel Group Controller Module (CGC2)

The CGC2 is used as a scheduler and a controller. It schedules when the MRFM-S operates and

routes the data from the MRFM-S to the MC.

Configuration Module (CFM)

The CFM is a field replaceable PWA board. These non-volatile memory cards store the Reader

configuration file. They are field-replaceable without using any tools.

Distribution Module (DSM)

The DSM back plane provides interconnections between the plug-in modules in the Reader rack. It is

not field-replaceable.

The DSM is responsible for the following.

 Provides locations for all plug-in Reader modules and the Lane Kit RF modules

 Distributes DC power from the PSMs to the necessary modules in the Reader rack

 Carries RF data and control signals between primary and secondary CTMs and all MRFM-Ss

 Carries synchronization and redundancy mode signals between primary and secondary CTMs and

the SPM

 Carries data between primary and secondary CTMs and primary and secondary CFMs

 Carries data between primary and secondary CTMs and primary and secondary LPMs

Synchronization

CAUTION:

On one redundant reader of a synchronization network, the

synchronization connection should be looped back and this reader

will declare sync even if it is disconnected from the other readers.

Readers must be synchronized if they have overlapping capture zones, are connected in an IR

network, or if Reader-to-Reader RF interference is present.
