ICOM OPC-2389 Connection Cable Instructions

Introduction

Thank you for purchasing this Icom product. The OPC-2389 connection cable is used to connect a serial communication device to the VE-PG3 or VE-PG4. Please read all instructions carefully and completely before using the cable.

Connecting the OPC-2389

Step 1: Turn OFF all devices that are connected to the VE-PG3 or VE-PG4, and then connect the OPC-2389 as shown below.

Diagram Description: The VE-PG4 rear view illustrates the connection points. The OPC-2389 cable connects to the [EXT1] port. It is crucial to ensure the connector is inserted top side up.

Note: This example demonstrates connecting a serial communication device to the [EXT1] port.

Important Cautions:

• Verify that both the repeater and the VE-PG3 or VE-PG4 are turned OFF when connecting or disconnecting the cable.
• Always hold the connector body when connecting or disconnecting.
• If other cables are connected, needle-nose pliers can be used to carefully insert or remove connectors.
• Never pull the connector by holding the cable, as this will damage the cable.
• Never bend or pinch the cable.
• Never place a heavy object on the cable.
• Never touch the cable with wet hands.
• Always connect the cable correctly. An incorrect connection could damage the VE-PG3 or VE-PG4 and/or the connected device.
• Never add pulling tension to the cable.
• Only use the OPC-2389 with VE-PG3 and VE-PG4 devices.
• Compatibility with all serial communication devices is not guaranteed.

Replacing the Connector

If the cable becomes damaged, replace the connector(s). Make wire connections as described below. Spare connectors (Manufacturer: DDK, Name: 232D-04S1B-DA5-FA) are supplied with the VE-PG3 or VE-PG4.

The connector consists of two parts: a black base and a clear insert. Do not lock the connector parts before inserting all wires.

Step 1: Insert the wires into the holes according to the assigned pin numbers.

Diagram Description: The connector is shown with wires inserted. The wires for each hole are assigned by color. Refer to the illustration below for wire color to pin number mapping.

Step 2: Press the clear insert down until it locks in place.

Note: Once the insert is locked, it cannot be released.

Recommendation:

If the connector is reconnected approximately 30 times, it is recommended to cut the wires near the connector and replace it with a new one. Ensure the cable is removed from the VE-PG3 or VE-PG4 before cutting the wires. Do not cut the wires too short, as this will make reconnection difficult.
