Manual

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.

V1- V1+	V2- V2+
PWR1	PWR2

PWR1	PWR2

STEP 1: Insert the negative/positive DC or AC wires into the V-/V+ terminals.

STEP 2: To keep the DC or AC 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 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.

You may then use a console terminal program, such as Moxa PComm Terminal Emulator, to access VPort 351’s console configuration utility.
