Common issues, fixes, installation tips, and maintenance guidance for Acclaim fixtures.
I'm experiencing interference with my Aria Wireless DMX system. What causes this and how do I resolve it?
Aria operates on 2.4 GHz, sharing spectrum with Wi-Fi, Bluetooth, and other ISM devices. To reduce interference: change the Aria channel (0-14) to avoid overlap with nearby Wi-Fi channels 1, 6, or 11. Move transmitters away from Wi-Fi access points by at least 10 feet. Use the Aria Range Extender for installations with metal obstructions or long distances. Verify all receivers show solid link status after channel change.
Can I use the ALPS-400-24 power supply with 208V single-phase AC power?
Yes, the ALPS-400-24 accepts universal input voltage of 100-277VAC, 50/60Hz, so 208VAC single-phase is fully compatible. Wire Line 1 (hot) to the brown wire, Line 2 (hot) to the blue wire, and ground to the green/yellow wire. Always verify your incoming voltage with a meter before energizing, and ensure the enclosure is properly grounded per NEC requirements.
Is the ALPS-60-24 driver compatible with TRIAC dimming?
ALPS power supplies (such as the ALPS-96-24, ALPS-200-24, and ALPS-400-24) are used in non-dimmed or DMX/0-10V configurations when paired with an AL Driver 1 module. They are not compatible for TRIAC or ELV systems.
My fixture is powered but not responding to DMX. What should I check first?
Verify DMX cable continuity with a DMX tester—check for opens, shorts, or reversed polarity on pins 2 and 3. Confirm the fixture's DMX address matches what your controller is sending. Ensure the last fixture in the daisy chain has a 120-ohm terminator installed. Check that the fixture is set to DMX mode, not standalone. If using a splitter (ZDM-6 or RDS-6), verify the splitter is powered and receiving valid input signal.
Can I use a City Theatrical DMXcat to address and configure Cylinder One fixtures?
Yes, Cylinder One supports RDM (Remote Device Management), and the City Theatrical DMXcat is RDM-compatible. Connect the DMXcat to the DMX line, navigate to RDM Discovery, and the tool will find all RDM-capable fixtures. Select each fixture to view or change its DMX start address, personality (DMX mode), and other parameters. Ensure fixtures are powered and DMX cabling is intact before attempting RDM discovery.
How do I set up the RDS-6 outdoor DMX splitter, and what should I check if outputs aren't working?
Connect 24VDC power to the RDS-6 input terminals, then connect DMX input from your controller. Each of the six outputs is optically isolated. If outputs aren't working: verify the power LED is lit (confirms 24V power). Check that DMX input signal is valid using a tester at the input port. Test each output individually with a known-working fixture. If specific ports fail while others work, the splitter may have internal damage and should be replaced.
My fixture is only outputting white light even though I'm sending color commands via DMX. How do I diagnose this?
Check the fixture's DMX mode/personality setting—some modes are white-only or static CCT. Verify you're sending values to the correct DMX channels for RGB or RGBW control per the fixture's channel map. Confirm the DMX start address matches between fixture and controller. Test by sending full red (255) on the red channel while other colors are at zero—if you get white, the fixture may be stuck in a fallback mode. Power-cycle the fixture and re-check the mode setting.
Can I connect a timer to an AL Driver 800 for scheduled on/off operation?
You can place a timer or contactor on the 100-277VAC input feeding the AL Driver 800. When power is restored, the AL Driver will resume its last stored settings from non-volatile memory. So if you had it set to:
Manual mode with a static color mix, or
Auto mode with a chase pattern
The fixture(s) will come back on automatically in that same state when the timer energizes the circuit. This is the simplest approach for basic on/off scheduling without any external control system.
