UC-7420/7410 User’s Manual

Introduction

yYou can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

yKeep input wiring and output wiring separate.

yWhere necessary, it is strongly advised that you label wiring to all devices in the system.

Connecting the Power

Connect the 12-48 VDC power line with UC-7420/7410’s terminal block. If the power is properly supplied, the Ready LED will illuminate with a solid green color after 30 to 60 seconds have passed.

Grounding UC-7420/7410

Grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

SG

SG: The Shielded Ground (sometimes called Protected Ground) contact is

the left most contact of the 3-pin power terminal block connector when viewed from the angle shown here. Connect the SG wire to an appropriate grounded metal surface.

DC 12-48V

Connecting to the Network

Connect one end of the Ethernet cable to one of UC-7420/7410’s 10/100M Ethernet ports (8-pin RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected, UC-7420/7410 will indicate a valid connection to the Ethernet in the following ways:

8 1

8 1

The bottom right corner LED indicator maintains a solid green color when the cable is properly connected to a 100 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received.

The bottom left corner LED indicator maintains a solid orange color when the cable is properly connected to a 10 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received.
