Black Box SW590A-R2, SW591C manual Installation, Introduction, Setting the DIP switches

CODE OPERATED SWITCH II

3. Installation

3.1. Introduction

In addition to this manual, your Switch package should contain one standard switch unit and a wallmounted power supply. After you’ve unpacked the Switch, take a few minutes to look through this manual. You will need a screwdriver large enough to remove the case screws, and a small screwdriver or other edged tool for setting DIP switches. Also, you might want to refer to the manuals of the devices you plan to connect to the COS-II.

Installing the COS-II is a simple, three-step task that should take no more than an hour to complete. First, you’ll configure all of the DIP

switches for the internal options of the COS II. Then, you’ll specify DTE or DCE for each port by setting shunt jumpers. Finally, you’ll cable the Switch to your devices and connect power to the

COS II.

3.2. Setting the DIP switches

In order to set the DIP switches, you’ll need to open the case of the COS-II. There are several screws on each side. Remove them, and lift the case lid from the body of the COS-II. The board layout of your unit should match the diagram shown below (Fig.1).
