Prepare your rental inquiry

Date, city, venue and setup, event and pickup schedule.
Intended use, area dimensions and equipment already supplied by the venue or production.
Space dimensions, desired effect and preferred control method.
Stands, footswitch, remotes and transmitters: confirm kit contents and optional accessories.

Specify equipment only or whether setup, programming, operation and strike are also needed. Scope is confirmed in the proposal.

You do not need a final equipment list: tell us the result you want and the part you need help with. Availability and scope are confirmed in the proposal.

Features and connections

3Ch provides shared RGB; 5Ch adds dimmer and strobe; 15Ch provides per-pod RGB and programs. Mechanical aiming does not mean DMX movement.

The official repository lists V4.01a for serials 0424001111 and above, and V4.01b for 0424001110 and below. Both change D-Fi detection; check serial before choosing a file.

Prepare the system

Use grounded 100–240 VAC, 50/60 Hz power without a dimmer. Published consumption: 47 W at 120 V, 60 Hz and 45 W at 230 V, 50 Hz.
Secure tripod stability, fasteners and aiming before power-up. Overhead installation requires load-rated mounting and secondary retention by qualified personnel.
Select 3Ch, 5Ch or 15Ch, press ENTER, set address and confirm. Match console profile and do not share the line with a standalone master.

Questions and troubleshooting

Does the console change the whole bar together?

Per-pod control requires 15Ch and a matching profile.

In 15Ch keep channel 1 at 000–009 to avoid programs and raise dimmer on 2.
Test the first pod’s RGB on 4–6, then subsequent groups. Strobe/speed on 3 changes function with the program channel.
If programs still run, inspect mode and patch before editing scenes or updating firmware.

Does plugging in D-Fi disable the cable or remote?

The manual gives the D-Fi USB dongle priority.

Save settings and remove it for an independent wired DMX test. Do not connect generic USB accessories to the control port.
For D-Fi match accessory channel and TX/RX as well as personality and address. Wireless channel and DMX address have different purposes.
For ILS select iLS1–4 and check a compatible transmitter; do not treat it as an individual console patch by analogy.

Does BTAir miss the bar or the footswitch fail?

Bluetooth, footswitch and IRC-6 need separate checks.

Select bLE and match the displayed ID to the unit selected in BTAir; inspect device permissions and connection without deleting show configuration.
For the footswitch, check power, 9 V battery, local program and SEt > ir as specified in the manual. Check Blackout in a safe area.
If only one control path fails, keep another tested path for recovery. Record version and serial before updating; do not install another serial branch.

Quick reference

Precautions

Dry indoor use only; maximum 40 °C with 50 cm ventilation clearance. No rain or direct eye exposure.
Wireless range depends on conditions. Prepare a local fixed color or tested wired control for link loss.
Prepare updates outside show operation using the correct serial-specific file and official procedure. Firmware support does not make the port a charger.
