Multi-protocol RF Module Smart

The Multi-protocol RF Module Smart (MRFM-S) and Multi-protocol RF Module Smart Plus (MRFM-S Plus) 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 as well as the active protocol TDM.

The MRFM-S design includes a software command for adjusting the transmitter peak output power.

ATTENTION: When installing or replacing an RF module, the lane should be re-tuned. A reader can only

contain either MRFM-S or MRFM-S Plus modules but not both.

The RF Module transmits recovered OBU data as messages to the CGC. After the messages are processed by the

CTM, a transaction message is normally sent to the LC.

Power Supply Module (PSM)

The PSM AC mains power requirement is 95-230VAC (60Hz+/-2 Hz) at 10A max input current.

The PSM is field replaceable and provides:

• A power switch and a 10A fuse

• +5V and +15V DC power outputs

• +5V and +15V LEDs to indicate power supply output status

In the redundant configuration, both the primary and secondary PSMs are normally powered on. The primary

PSM provides power to the primary CTM and the secondary PSM provides power to the secondary CTM. Both

PSMs share the RF module load.

In the event of failure of one PSM, an automatic switchover will occur and the redundant PSM provides all the

power for the RF module load.

The PSMs are not interchangeable. The Primary and Secondary power supplies have different part numbers; a

result of being physical mirror images of each other.

Each PSM has a mains power fuse on the front panel: Time lag, 10 A @ 250 V, UL rated.

The power supply distribution is shown in Figure 4-1, page 141.
