CHAPTER 2: Introduction 2. Introduction Switching between data lines manually can often damage the connected equipment, because this relatively slow and imprecise action can cause data-line surges and spikes large enough to damage today’s sensitive circuitry. With the Local/Remote Electronic Switches, you can eliminate this potential hazard. Their electronic switching action provides surgeless, spikeless changeovers—something a mechanical switch just can’t do. In addition, these switches can be

LOCAL/REMOTE ELECTRONIC SWITCHES 3. Installation and Configuration 3.1 Before You Install Check the box and its contents before you begin installing your Local/Remote Electronic Switch. You should have received one Switch unit, one AC power supply, and one copy of this manual. If you didn’t receive all of these items, or if they have sustained damage that does not seem to be shipping-related, notify Black Box right away. If they have sustained impact or water damage that seems to have happened d

CHAPTER 3: Installation and Configuration 3.2 The Setup Procedure Installing and configuring a Local/Remote Electronic Switch is relatively quick and easy, and will vary only slightly depending on which model you’ve chosen. Follow these steps: (Steps 1 through 4 are for remotely switched applications only:) 1. Make sure that the Switch is unplugged (is not receiving AC power). Open the Switch by unscrewing the two screws on the bottom of the unit (save these screws) and removing the top of the u

CHAPTER 3: Installation and Configuration (text continued from page 9) 3. If you will be performing remote switching using a cable that is unterminated at the Switch end, attach the cable’s wires to the appropriate positions of the 4-position terminal block labeled “TB1” (refer to Figures 3-1 through 3-3 on pages 10 through 12 and to Tables 4-1 and 4-2 on pages 20 and 21). Connect the ground of the remote driver, or one side of the dry contact, to (either of) the terminal block’s ground pin(s).

CHAPTER 4: Operation 4.2 Remote Switching When you do remote switching, keep these things in mind: • The knob on the Switch’s front panel must be in the “REMOTE” position. • The Switch interprets any voltage more negative than approximately 1.4 volts as a “low” and any voltage more positive than approximately 1.4 volts as a “high” (see the “Remote Input Logic Levels” spec in Chapter 1 for maximum and minimum switching points). • In dry-contact applications, the Switch will read a “low” when the
