This document provides installation instructions for the recommended C-5 system optical transceivers by Genway Security Technology Development Co., Ltd. It includes specifications for the optical transceivers, information on the recommended models, and installation precautions.
This manual explains the installation of optical transceivers (光端机) for the Genway C-5 security system. It lists the required specifications for video, data and audio channels and provides the recommended transceiver models from Guangzhou Light Bridge.
The document also details wiring connections between the main and sub switches, RJ45 pin assignments, BNC coaxial connections, and grounding requirements to ensure reliable operation and protection against lightning and noise. This manual is written in Chinese.
| Video channel interface | BNC unbalanced, 75 Ω, 1 Vp‑p typical, 1.3 Vp‑p dynamic range, 6.3 MHz bandwidth |
|---|---|
| Data channel interface | Standard RS‑485 half‑duplex, 0‑1 Mbps |
| Audio channel interface | Full‑duplex, 600 Ω, 0.4 Bm typical, 4 kHz bandwidth |
It uses a BNC unbalanced connector with 75 Ω impedance, 1 Vp‑p typical level and a 6.3 MHz bandwidth.
The RS‑485 data channel supports a half‑duplex rate of up to 1 Mbps.
The transceiver’s power‑adapter ground pin must be removed and the switch chassis must be grounded to avoid breaking the C‑5 system’s floating ground.
