Enclosure Metal with black matte finish Dimensions (HWD) 1.51" x 5.55" x 5.45" (3.84 cm x 14.10 cm x 13.84 cm) Weight 1.1 lb (0.499 kg) AXlink Power 12 VDC @ 230 mA 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 12 3 4 5 6 7 8 Value 1 2 4 8 16 32 64 128 1 2 3 4 5 6 7 8ON 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. .. Boxes are 96 through 127. .. Panels are 128 through 255. 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. 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 wires. 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. The maximum wiring distance between the Central Controller and interface is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The table below lists wire sizes and maximum lengths allowable between the VOL3 and Central Controller. 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. Wiring Guidelines at 230 mA Wire Size Maximum Wiring Length 18 AWG 510.31 feet (155.54 m) 20 AWG 371.29 feet (113.17 m) 22 AWG 201.29 feet (61.35 m) 24 AWG 126.88 feet (38.67 m) AXB-VOL3 Three-Channel Volume Control Installation AXlink connector Install the AXlink data/power bus wiring as shown in FIG. 2.

Channel Settings Commands Use the AXB-VOL3 channel settings listed for ramp up, ramp down and mute operations.. AXB-VOL3 Channel Setting Commands Channel Description Channel Description 1 Ramps channels 1 and 2 up. 7 Ramps channel 2 up. 2 Ramps channels 1 and 2 down. 8 Ramps channel 2 down. 3 Mutes channels 1 and 2. 9 Mutes channel 2. 4 Ramps channel 1 up. 10 Ramps channel 3 up. 5 Ramps channel 1 down. 11 Ramps channel 3 down. 6 Mutes channel 1. 12 Mutes channel 3. Ramping a volume channel while the mute channel is on will NOT automatically turn off the mute channel (will not restore) but the ramping will still occur and the volume change will be noticed when the mute channel is turned off. For setting ramp rates and presets, see SEND_COMMAND programming instructions below. For reading current volume levels and displaying bargraphs see CREATE_LEVEL and SEND_LEVEL programming instructions. Volume channels 1 through 3 use levels 1 to 3 respectively. When controlling levels, such as with an active bargraph, there is no LED indication of volume changes. Levels .. 1 = Output #1 .. 2 = Output #2 .. 3 = Output #3 AXB-VOL3 Three-Channel Volume Control Programming Send_Commands System Send_Commands are stored in the Axcess Control System. AXB-VOL3 Send_Commands PLT Ramps specified channel(s) from current level to a specified preset level or percentage at the current rate or optionally in a specified amount of time.
