4.1 Case 1: Remote Power Feeding Relay with PMC Module to
Extend Surveillance Distance from 2 Km to 4 Km (PMC 600)
Objective:
Using PMC 600 module to relay and supply power to remote PMC module in
order to extend surveillance distance from 2KM to 4 KM without the use of repeater.
Network Architecture:
A PMC 600 module is used to relay power to a remote PMC 100 module (located
2Km away at a location with no available power source) to enable the later to extend its
surveillance distance by another of 2Km without using any repeater.
Where:
PMC 600A is the PMC 600 module OT side terminal (set CPE), and has its own
power source of 90~240v AC.
PMC 600B is the remote PMC 600 module RT side terminal (set CO), without its
own power source. It derives its power from PMC 600A (located 2Km away) via
phone line (RJ11)
，
PMC 100A is the PMC 100 module (set CPE) without its own power source. It
derives its required power (5v DC) from PMC 600B via phone line (RJ11). Hence
it is able to work with PMC 100B (located another 2Km away).
PMC 100B is the PMC 100 module (set CO), and its power source is DC (5v).
BEWARE!!
Be careful! High-voltage power supply (hvps) may be present in phone line.
