Installation and Operation

Installation Overview

To install and set up the YCS SW2 A, follow these steps:

1Mount the YCS SW2 A on a rack shelf, furniture, or projector mount if desired.

2Connect your composite video and/or S-video input source(s) to one or both YCS input connectors.

3Connect your output device(s) to the YCS composite video and/or S-video output connector(s).

4Connect the audio connectors of your input sources to the YCS audio input connectors.

5Connect the audio connectors of your output device(s) to the YCS audio output connectors.

6If necessary, wire the provided 2-pin captive screw connector to the external power supply. (See “Wiring the Power Connector,” later in this chapter.)

7If using autoswitching, insert the provided 3-pin captive screw plug into the 3-pin connector on the YCS back panel, and jumper-connect pins 1 and 2, and 2 and 3, together. (See “Autoswitching,” later in this chapter.)

8If using contact closure for input selection, connect a remote contact closure device to pins 1, 2, and of the captive screw connector on the YCS rear panel. (See “Contact Closure,” later in this chapter.)

9Apply power to the YCS SW2 A and to the input and output devices.

Mounting the YCS SW2 A

The YCS SW2 A can be set on a table; mounted on a rack shelf; mounted under a desk, podium, or table; or attached to a projector mount.

Tabletop use

Four self-adhesive rubber feet are included with the YCS SW2 A. For tabletop use, attach one foot at each corner on the bottom of the unit, and place the YCS in the desired location.

Rack mounting

For optional rack mounting, do not install the rubber feet. Mount the switcher on any of the following rack shelves:

•RSB 123 1U, 3.5" Deep VersaTools Basic Rack Shelf (part #60-604-20)

•RSF 123 1U, 3.5" Deep VersaTools Rack Shelf Kit (part #60-190-20)

•RSB 126 1U, 6" Deep Basic Rack Shelf (part #60-604-10)

•RSU 126 1U, 6" Deep Universal Rack Shelf Kit (part #60-190-10)

•RSB 129 1U, 9.5" Deep Basic Rack Shelf (part #60-604-01)

•RSU 129 1U, 9.5" Deep Universal Rack Shelf Kit (part #60-190-01)

•MBU 123 Mini Under-desk Mount Kit (part #70-212-01)

•MBB 100 Back-of-Rack Mount Kit (part #70-367-01)

•Projector mounting kits: PMK 100 (part #60-217-01), PMK 250, (part #70-526-02 or 70-526-03), PMK 300 (part #70-374-01), PMK 350 (part #70-563-02 or 70-563-03), or PMK 450 (part #70-618-02 or #70-618-03).

UL rack mounting requirements

The following Underwriters Laboratories (UL) requirements pertain to the safe installation of the equipment in a rack.

1.	Elevated operating ambient temperature — If the
	equipment is installed in a closed or multi-unit rack
	assembly, the operating ambient temperature of the
	rack environment may be greater than room ambient
	temperature. Therefore, install the equipment in an
	environment compatible with the maximum ambient
	temperature (Tma = +113 °F, +45 °C) specified by Extron.
2.	Reduced air flow — Install the equipment in a rack so that
	the amount of air flow required for safe operation of the
	equipment is not compromised.
3.	Mechanical loading — Mount the equipment in the rack so
	that a hazardous condition is not achieved due to uneven
	mechanical loading.
4.	Circuit overloading — Connect the equipment to
	the supply circuit and consider the effect that circuit
	overloading might have on overcurrent protection and
	supply wiring. Appropriate consideration of equipment
	nameplate ratings should be used when addressing this
	concern.
