[. . . ] This limitation of liability, however, will not apply to claims for personal injury. Some states do not allow a limitation of how long an implied warranty last. Some states do not allow the limitation or exclusion of incidental or consequential damages for consumer products. In such states, the limitation or exclusion of the Limited Warranty may not apply. [. . . ] Each line-level channel, opto-isolated from system ground, can be configured for balanced or unbalanced line operation. The AXB-VOL3 is programmable for 128 steps of audio level, audio mute, variable ramp speed and level presets. The AXB-VOL3 connects to Axcess control systems using the 4-wire AXlink data/power bus; it can be used for remote or rack mount applications.

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. 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 Central Controller supplies power via the AXlink cable or external 12 VDC power supply. [. . . ] Syntax: SEND_COMMAND VOL, 'P<output channel 0-3>L<level 0-255|0-100%>[T<Time 0-255 in tenth second increments>]' Variables: Output Channel = Channel numbers 1, 2 or 3. Level 0 is lowest volume (same as mute) and 255 or 100% is maximum volume. Example 1: SEND_COMMAND VOL, 'P0L50%' Ramps both channels to 50% mid level volume at the current ramp rate. Example 2: SEND_COMMAND VOL, 'P1L255T20' Ramps channel 1 to highest level volume in 2 seconds. [. . . ]
