This document is a user manual for a one-channel coaxial converter, providing instructions for product usage, troubleshooting, and technical specifications.
This manual describes the main features of the One-Channel Coaxial Converter, including its built‑in RS485/RS422, Manchester and BI‑Phase receiving interfaces and selectable protocols via DIP switches. It also details the front‑panel ports, power requirements, and dimensions of the device.
Installation instructions cover mounting, connecting power, video input/output, and controlling cables. The guide explains how to set the device address, protocol, and baud rate using DIP switches, how to adjust jumpers for different communication modes, and provides a troubleshooting table for LED indicators and common error conditions.
