Device DIP Switch Channel LEDs Rear Panel Components: AXlink connector Volume Channel connectors Enclosure Dimensions (HWD) Weight AXlink Power 4-pin, captive wire connector, receives power and information via the AXlink and AXlink Central Controller. 6-pin, captive wire connectors that control audio level, audio mute, variable ramp speed and level presets of up to 3 devices. Metal with black matte finish 1. 51" x 5. 55" x 5. 45" (3. 84 cm x 14. 10 cm x 13. 84 cm) 1. 1 lb (0. 499 kg) 12 VDC @ 230 mA An 8-position DIP switch used to set the AXlink device number for the AXB-VOL3. The LEDs individually light indicating a change in channel levels. 2 AXB-VOL3 Three-Channel Volume Control Installation Installation DIP Switch Settings Use the device DIP switch to set the AXB-VOL3 AXlink device number. You can set it as one of 255 devices in an Axcess control system. Set the device number with the total of all ON (down) switches. As an example, the DIP switch below defines Device 128. Device DIP Switch Settings Position Value 1 1 2 2 3 4 4 8 5 6 7 8 O 12345678 N 16 32 64 128 The device number takes effect only upon power-up. If you later change the device number, remove and reconnect the AXlink connector to enter the new device number into memory. AMX standard device numbers are assigned as follows: Cards are 1 through 25. The AXB-PCCOM emulates a touch panel when set in the panel range. Wiring Preparing and connecting captive wires 1. Strip 0. 25 inch of wire insulation off all wires. Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section. Do not tighten the screws excessively; doing so may strip the threads and damage the connector. Wiring guidelines The interface requires a 12 VDC power to operate properly. The interface uses a PSN2. 8 power supply. The Central Controller supplies power via the AXlink cable or external 12 VDC power supply. [. . . ] Example 2: SEND_COMMAND VOL, 'P1L255T20' Ramps channel 1 to highest level volume in 2 seconds. PR Sets the ramp rate of the specified channel(s) where the time is the time to ramp the full range both down to up and up to down or optionally just down to up or just up to down. Syntax: SEND_COMMAND VOL, 'P<output channel 0-3>R<ramp rate 0-255 in tenth seconds>[U|D]' Variables: Output Channel = Channel numbers 1, 2 or 3. Output channel 0 = both channels 1 and 2. [. . . ]
