Wiring the Relay Output
RELAY 1
RELAY 2
Normal Open
Common
Normal Close
The VPor 351 has two sets of relay
outputs, labeled RELAY 1 and
RELAY 2, located on the 8-pin
terminal block connector. Each relay
output uses 3 of the contacts on the
8-pin terminal block. The terminal
block is located on the VPor 351’s top
panel.
The relay output can be configured for:
1. System alarm: power failure or disconnected network
2. Event alarm: VMD (Video Motion Detection), video loss, and Digital
Inputs
ATTENTION
The maximum current and power capacity of the relay output is 24
VDC @ 1A. Please be careful not to exceed this power
specification.
ATTENTION
Before connecting the VPort to the DC/AC power inputs, make
sure the DC power source voltage is stable.
Wiring the Digital Inputs
The VPort 351 has two digital inputs, labeled DI1 and DI2. Each DI consists of
two contacts of the 6-pin terminal block connector located on the 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 the VPort 351’s top panel.
Communication Connections
VPort 351 models have one RJ45 console port (RS-232 interface), and 1
10/100BaseT(X) Ethernet port or 1 100BaseFX (SC-type connector) fiber port.
RS-232 Connection
VPort 351 has one RS-232 (10-pin RJ45) console port, located on the top panel.
Use either an RJ45-to-DB9 or RJ45-to-DB25 cable (see the cable following
wiring diagrams) to connect VPort 351’s console port to your PC’s COM port.
