Rear Panel: INPUT A VIDEO INPUT A AUDIO INPUT B VIDEO INPUT B AUDIO BNC female connector 6-pin cable jack, audio and control input BNC female connector 4-pin cable jack Captive-wire screw terminals Allows stereo (unbalanced) line-level audio Switching Modes: Automatic AV2SM switches to the A source; if no input is detected the AV2SM automatically switches to the B source. If both A and B sources are present, the default is the A source. AV2SM determines which source to use based on the state of the SELECT pin on the rear panel. Molded black matte plastic · Two 4-pin cable connectors · One 6-pin cable connector · One 2-pin power connector Optional Accessories AC-RK Accessory Rack Kit Manual Enclosure Included Accessories 2 AV2SM A/V Switcher Installation Installation You can install the AV2SM on any flat surface that has unobstructed access to both the front and rear panel connectors. Automatic and Manual Switching Mode Settings You can select the switching mode by setting two internal jumpers on the circuit card inside the enclosure. You will need a Phillips screwdriver to open the enclosure. To set the switching mode: 1. Discharge the static electricity from your body and screwdriver. 2. Unplug all connectors from the front and rear panel of the AV2SM. 3. Turn the enclosure upside down and remove the two Phillips-head screws. 4. Pull the enclosure apart and turn the bottom half, containing the circuit card, right-side up. 5. Choose the desired switching mode: ! For automatic mode (FIG. 2), place the 2-pin jumper on the E1 connector pin's one and two. Repeat for the E2 connector. E1 E1 E2 2 AUTO AUTO MAN. MAN. FIG. 2 Automatic mode settings ! For manual mode (FIG. 3), place the 2-pin jumper on the E1 connector pin's 2 and 3. Repeat for the E2 connector. E1 E1 E2 2 AUTO AUTO MAN. MAN. FIG. 3 Manual mode settings AV2SM A/V Switcher 3 Installation Wiring Guidelines The maximum wiring distance between the Central Controller and the AV2SM is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts available at the Central Controller's power supply. The maximum lengths allowable between the AV2SM and the Central Controller are as follows: Wiring Guidelines Wiring size Maximum wiring length 18 20 22 24 1805.7 ft (550.37 m) 1142.4 ft (382.20 m) 712.2 ft (217.07 m) 448.9 ft (136.82 m) Preparing captive wires 1. Strip 0.25 inch of wire insulation off all wires. 2. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. 3. Tighten the screws to secure the wire in the connector. Do not tighten the screws excessively; doing so may strip the threads and damage the connector.

When you use manual switching mode, the Select pin (rear panel) is taken low to select the B source and high to select the A source. A low can be an external relay closure or a voltage level from 0 VDC to 0.8 VDC. A high can be an open set of contacts or a voltage level from 3.3 VDC to 12.0 VDC.
