Wiring the Relay Output

The VPort 254 has two sets of relay output, relay 1 and relay 2, which are located on the 8-pin

terminal block connector. Each relay output consists of the 3 contacts of the terminal block on the

VPort 254’s top panel.

The relay output can be set up for:

1. System alarm: Power failure, Video loss and Network disconnected.

2. Event alarm: VMD (Video Motion Detection) and Digital Inputs (firmware version V2.0 and

later)

ATTENTION

The current and power capacity of the relay output is a maximum of 24 VDC @ 1A. You should

be careful not to exceed this power specification.

Wiring the Digital Inputs

VPort 254 has four sets of digital input, DI1, DI2, DI3 and DI4. Each DI

consists of two contacts of the 10-pin terminal block connector on VPort’s top

panel. Top and front views of one of the terminal block connectors are shown

here.

STEP 1: Insert the negative (ground)/positive DI wires into the ┴/I1 terminals.

STEP 2: To keep the DI wires from pulling loose, use a small flat-blade

screwdriver to tighten the wire-clamp screws on the front of the terminal block

connector.

STEP 3: Insert the plastic terminal block connector prongs into the terminal

block receptor, which is located on VPort 254’s top panel.
