Network Monitoring

The optional LIFELINE Status Monitoring System (LL-SG2) enables you to monitor the SG 2000 from a headend or a remote location. The transponder consists of a plug-in module mounted on the main RF board. If you do not employ status monitoring and use redundant receivers and/or transmitters, a manual control board (MCB) occupies the same position on the main RF board.

The entire LIFELINE system includes:

LL-CU control units Are connected to the system at the headend and interrogate each SG 2000 field transponder with FM outbound and inbound transmissions. A variety of outbound and inbound frequencies can be selected depending on the configuration of the system. The control unit reports this information to the status monitor computer.

Includes an IBM-compatible computer that is connected to the control unit (CU) through an RS-232 link. LIFELINE software enables the operator to view measurements taken by the transponders.

Installed in individual field components, this unit interfaces with the CU at the headend. It reports such parameters as: forward amplifier dc current draw, ac and dc voltage, temperature, automatic drive unit (ADU-*) drive voltage, management and control of RF ingress switching, and tamper status.

Configuration
