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 flathead

screwdriver to tighten the

connection.

STEP 3: Insert the terminal block

connector into the receptor on the

VPort’s top panel.

Communication Connections

The VPort 251 has an RS-232 console port and a 10/100BaseT(X) Ethernet

port, which both use RJ45 connectors.

RS-232 Connection

The RS-232 console port is on the top panel and uses a 10-pin RJ45 connector.

Use an RJ45-to-DB9 or RJ45-to-DB25 cable to connect your PC COM port to

the console port. Cable wiring diagrams are shown below. You may then use a

console terminal program, such as Moxa's PComm Terminal Emulator, to open

the VPort’s console configuration utility.
