Introduction: Choosing between a standard interface A17 and an FB4 version is a control-chain decision that determines where the control signal enters, what processes it, and how many conversion boxes sit between the console and the galvos.
The fixtures may share the same housing and beam path, but the difference shows up during focus and cueing, after the truss is up and the cable is already run. The path from console output to beam output is where that decision plays out, and following it is the fastest way to settle addressing, channel modes, and network layout before anyone climbs a ladder.
Control planning is cheap on paper and expensive in the air. Before a fixture is flown, the integrator decides which console output feeds the laser, whether the run is DMX512, Art-Net, or ILDA, where the network switch sits, which universe each unit occupies, and whether a second signal path stays available as a fallback. An A17 RGB moving head laser weighs 24 kg net and needs service access, so every cable decision made on the ground stays on the ground until load-out. Rework is what you are trying to avoid. A fixture delivered with the wrong interface level can add an external conversion box, a power outlet in the rig, and an extra hop that has to be located and fixed when a unit stops responding mid-show. Planning the route once — console output, switch position, DMX and Art-Net distribution, one ILDA line held in reserve, and a written address list — means the lasers land in the right universes on the first attempt. That one hour of planning can save a lift, a re-cable, and a dark stage.
Whichever version you specify, the signal follows the same general path: a command source, an entry point on the fixture, a processing stage, and the scanner that turns data into a beam. What changes is the entry format and how much processing happens inside the housing.
A console or media server can send the show over DMX512 through a 3-pin connection, over Art-Net through the network port, or over a 25DB ILDA line, and the A17 accepts all three. DMX512 is the familiar route for small groups and single fixtures, and it needs one run per chain. Art-Net carries many universes over one Ethernet cable, which suits a full rig but puts real weight on switch placement and cable quality. The 25DB ILDA port uses the standard differential signal set that Pangolin documents for X, Y, RGB, and interlock data, with ±5V input on the fixture, and easy ILDA is available as a direct feed. Many integrators keep an ILDA line available as an independent backup for network problems.
On the A17 FB4 versions, Pangolin FB4 hardware sits inside the fixture, so network media server control arrives without an external ILDA conversion box in the air. That is the practical difference between integrated network hardware and an external converter: fewer connections, fewer failure points, and less rack space. Channel mode then decides how much of the show each fixture sees — the A17 offers 5CH, 17CH, 18CH, 27CH, and 52CH, from quick beam and cue work up to full per-fixture control. Building an array means writing the address list against the chosen mode so no two units share an address. The 40K galvo scanning hardware in each unit handles the actual drawing, and RDM bidirectional communication lets you read status and addressing back over the link instead of checking every fixture in person.
The A17 family covers two interface levels: A17-20W and A17-30W in the standard interface version, and A17-20W(FB4) and A17-30W(FB4) with integrated Pangolin FB4 hardware. Both levels support DMX512 over 3-pin, 25DB ILDA, easy ILDA, and Art-Net, and both offer the five channel modes along with the same scanner platform. The FB4 board is an option tied to specific models; it is available only on the FB4 versions, so the model code on the quote is what confirms it. Choosing between the two is mostly a question of what already exists in your control chain. If the show is driven from a media server over Ethernet and programmed in Pangolin software, the FB4 version takes a box out of the rig and shortens the signal path. If the project is a DMX console running the fixtures directly, or your team already owns external conversion gear it trusts, the standard interface version does the job. For larger fleets, DMX online firmware upgrade is worth factoring in: firmware can be pushed through the DMX chain rather than opening each fixture, which matters when dozens of units share a rig and a tour schedule. One step belongs in every project regardless of which version you pick. Send the console model, universe count, planned switch location, target channel mode, and fixture count to our integration team before the order is confirmed, so console compatibility, the channel map, network design, and firmware behavior are settled while the drawing is still editable.
The version you choose decides how much gear travels with the lasers. A standard interface A17 gives you a flexible fixture that works with the DMX, Art-Net, and ILDA infrastructure most stages already have. An FB4 version puts the network media server inside the housing and takes an external converter out of the chain. Both share the same interfaces, channel modes, and galvo platform, so the decision comes down to your control workflow, your team's programming habits, and how many boxes you want in the air. When you compare options from an RGB moving head laser supplier, ask for the exact model code, the channel map for your chosen mode, and the network plan in writing — that is what makes the first focus session run without surprises. Send your project details through the quote list — console type, universe plan, fixture count, and preferred channel mode — and we will confirm the version and configuration that fit your drawing.
A：All four connection types remain available. The A17 FB4 versions keep DMX512 3-pin, 25DB ILDA, easy ILDA, and Art-Net ports, and add integrated network media server hardware inside the housing. Network control from a media server or Pangolin software arrives directly at the fixture instead of passing through an external FB4 or ILDA converter, which removes a box, a power point, and a long analog run from the rig. Input format remains flexible, so the same fixture can follow your existing workflow.
A：The FB4 hardware is available on A17-20W(FB4) and A17-30W(FB4). The standard A17-20W and A17-30W come with the full interface set — DMX512 3-pin, 25DB ILDA, easy ILDA, and Art-Net — but without the integrated Pangolin board. FB4 is an option rather than standard across the series, so confirm the exact model code on the quote before you commit the fixture to a drawing.
A：The A17 supports five channel modes: 5CH, 17CH, 18CH, 27CH, and 52CH. A 5-channel setup is enough for simple beam and color work, while 27CH and 52CH give programmers more granular control across a multi-fixture array. Pick one mode for the whole fleet and keep it consistent, because the address list and cue structure are built around that number from day one.
