Automatic and Manual Switching Mode Settings You can select the switching mode by setting two internal jumpers on the circuit card inside the enclosure. Turn the enclosure upside down and remove the two Phillips-head screws. Pull the enclosure apart and turn the bottom half, containing the circuit card, right-side up. 2), place the 2-pin jumper on the E1 connector pin's one and two. 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.
