Module Descriptions

Smart Multi-protocol RF Module (MRFM-S)

Function

Executes frame functions triggered by command

or configuration messages and timing signals

received from the CTM via the DSM.

Executes the over-air aspects for a protocol

within each frame, generating the analog RF

signal that is sent to the OBU via the antenna.

Receives the analog RF signal collected from the

OBU via the antenna and recovers the data

content from the over-air protocol messages.

Reports the recovered data and status

information as messages that are sent to the CTM

via the DSM.

Output Power = 33dBm + 0.6dBm

Units per Reader

One MRFM-S for each antenna. A maximum of 8

MRFM-S per Reader.

Redundant

Normal State
