Wiring Connection
1.
Fiber connection methods: Cj-MF series belongs to single optical port device, suitable for point to point connection. As
shown in the figure below, the optical fiber must cross connection, namely the RX connect other side TX, and TX to RX
accordingly.
2. V+, V-, SHIELD respectively connect with anode, cathode of DC power supply and shielding ground.
DIN-Rail Installation
In order to use in industrial environments expediently, the device adopt 35mm DIN-Rail installation, the installation steps as
