Mooncell B1200S Sphere LED Controller
7.8M-pixel drive for sphere & ring LED screens · 12 Gigabit outputs · 4K60 in · optional Genlock
A sending controller built for non-rectangular canvas: twelve gigabit ports that tile sphere, circular and ring LED screens in any configuration up to 7.8 million pixels, with 4K-class input, optional Genlock and active 3D — supplied factory-direct by Excelled, a trusted LED display manufacturer and controller partner for global B2B projects.
B1200S Sphere LED Controller at a Glance
What is it? Mooncell’s sphere LED controller: a 12-port sending controller engineered for irregular-shaped LED displays — spheres, circular rings, arches and other non-rectangular canvases — distributed factory-direct by Excelled Display.
How big a screen can it drive? Up to 7.8 million pixels across 12 gigabit Ethernet ports, with per-port loads tiling in any horizontal or vertical configuration and an overall canvas up to 7,680 pixels wide or (by default) 4,096 high.
What video does it take? HDMI 2.0 or DP 1.2, one at a time, each up to 3840×2160@60Hz — full 4K support — with audio synchronized over the network cable.
What makes it a sphere controller? Load software built for non-rectangular layouts, optional Genlock (input + loop-through) for multi-controller creative canvases, active 3D hookup, and 30/50/60/120 Hz frame-rate compatibility.
Who is it for? Sphere screens, circular ring displays and creative LED architecture where rectangular video processors cannot partition the drive efficiently — or where the build demands Genlock synchronization.
Rectangular Processors Fail Spheres: the Case for a Dedicated Sphere LED Controller
An LED sphere is not a rectangle that happens to curve — its pixel rows vary in length, its seams run diagonally, and its load plan changes every few degrees of latitude. Standard sending controllers partition the canvas into rigid rectangular blocks, which wastes ports and complicates the mapping. The B1200S is Mooncell’s answer: 12 gigabit ports whose loads tile “vertically and horizontally in any configuration”, sized and offset precisely around a 7.8M-pixel budget — exactly the flexibility sphere and ring builds need.
Creative projects also throw timing requirements at the controller that rectangular walls rarely do. The B1200S carries an optional Genlock interface with one input and one loop-through output, so several B1200S units driving one huge spherical or multi-face canvas lock to the same sync source — no drifting frames between controller zones. For two B1200S in the same project, that is the difference between a seamless sphere and a visible split.

B1200S Interfaces: 4K Inputs, Audio, Twelve Gigabit Outputs and Genlock
The B1200S keeps a 4K60-class input bank: HDMI 2.0 and DP 1.2, each up to 3840×2160@60Hz, used select-one-of-two. When a GPU drives the source, the customizable canvas extends to 7,680 pixels wide or 4,096 tall. Output side, twelve gigabit ports carry the sphere load — 650,000 pixels per port at 8-bit and up to 655,360 in the 1280×512 per-port format — while RS232, USB and LAN handle control.
| Interface | QTY | Capability |

B1200S Load Rules: 7.8M-Pixel Budget, Sphere Limits and the F5 Height Switch
Sphere drive is a budgeting exercise: total pixels under 7.8M, each port under 655,360 in a 1280×512 format, and the whole canvas inside the sphere limits — width 640–7,680 pixels and height 480–4,096 in the default mode. The height cap carries a catch worth knowing before you spec: with the F5 setting enabled (the default), input height is limited to 4,096; disabling F5 lifts it to 8,192. Offset reaches 7,680 pixels wide and 4,095 high, which is how one B1200S places a huge rendered sphere canvas against the visible screen sections it feeds.

Loopback Backup, Dual-Master Backup and Monitoring on a 7.8M Sphere
A dark belt across a sphere is a very visible failure — and a re-commissioning nightmare on a curved structure. The B1200S carries Mooncell’s sending-stage reliability stack: Ethernet loopback backup reroutes data through surviving ports if a gigabit segment dies, and dual-master backup stands a second B1200S ready to take over the whole sphere if the active controller fails. For exhibition-center spheres and permanent creative architecture, the dual-master pair is the configuration that keeps the show on schedule.
Fleet visibility rides on top: host software monitors sending-card operating parameters and status, configuration readback restores a known-good load plan after any change, and gigabit Ethernet error-rate detection flags a degrading cable before pixels drop — valuable when the sphere’s cabling hides inside curved steelwork.
Genlock Input with Loop-Through and Active 3D on the B1200S
Creative LED canvases are frequently several controller zones pretending to be one screen. The B1200S’s optional Genlock interface — one input, one loop-through output — lets a master sync source drive a chain of controllers, so zones on opposite sides of a sphere advance frame-for-frame together. Where rectangular multi-controller builds sometimes tolerate drift, a rotating globe or a media facade cannot.
On the show side, the B1200S supports 3D display including active 3D: its 3D interface connects to the 3D transmitter, letting attraction and exhibition spheres run alternating-frame 3D content. Frame-rate compatibility to 120 Hz is part of the same design — the 3D workflow needs the fast alternating frame rate to serve both eyes.
B1200S Front Panel: 320×240 LCD, Rotary Knob and Menu Control
Commissioning a sphere is done on site, in front of the rack. The B1200S front panel pairs a 320×240 LCD with a rotary knob and ESC key: press the knob on the main screen to enter the menu, rotate to move through items, press to select, and rotate again to adjust values — long-press unlocks the menus when configuration is password-protected against casual changes. ESC returns or cancels at any level.
The same local workflow covers offline brightness adjustment for large screens, which the product introduction calls out as a headline capability: brightness changes apply directly at the unit without a PC session — the daily-lighting workflow for sphere installations that run unattended between shows.
Where the B1200S Sphere LED Controller Fits
Sphere and Globe LED Displays
Branded spheres — showrooms, brand pavilions, exhibition centers — are the B1200S home turf: 4K rendered content, non-rectangular partitioning, offline brightness between show sessions, and Genlock when the sphere spans multiple controller zones.
Circular Ring and Donut Displays
Ring displays wrap atriums, escalators and tower facades with canvases that are wide but short — exactly the 7,680-wide, 480–4,096-tall envelope the B1200S serves. RS232 puts the ring inside the building’s central control; loopback protects the ring’s long cable runs.
Creative LED Architecture and Event Screens
Arches, columns, curved media walls and festival builds run on custom resolutions and odd tilings. Preset and custom resolution support plus any-direction port tiling is what lets one B1200S drive shapes a standard sender would cut in wasteful rectangles.

B1200S Buying Guide: 5 Checks for a Sphere LED Controller
- Draw the unfolded canvas. Every sphere or ring install starts as a flattened pixel map. Total pixels must sit under 7.8M with width 640–7,680 and height 480–4,096 (or 8,192 with F5 off) — send us the drawing and we partition it port by port.
- Count controller zones. If the canvas needs more than one B1200S, price the optional Genlock board from the start — retrofitting sync onto a curved structure means re-running cabling inside the steelwork.
- Choose the input path. One 4K60 feed over HDMI 2.0 or DP 1.2. Content rendered at custom resolution? Confirm the GPU-canvas limits (7,680 × 4,096) match your rendering output before commissioning the media server.
- Decide redundancy depth. Loopback backup protects individual cable segments; dual-master backup means a second B1200S. Permanent architecture usually demands both; touring sphere rigs often run loopback only.
- Verify the receiving-card chain. Confirm your receiving cards support the per-port 1280×512 load format and the 3D or timing features you plan — the sending stage cannot create capability the cards lack.
Price and Cost Factors
B1200S pricing depends on quantity, the optional Genlock board, dual-master backup units, the 3D transmitter chain and cabling for 12 ports. A sphere project is priced as a drive system — receiving-card count, sender(s) and cable plan against one unfolded canvas — which is why we quote from the drawing, not from a parts list.
B1200S Sphere LED Controller FAQ
Q1 What is the B1200S sphere LED controller?
The B1200S is Mooncell’s 12-port sending controller designed for irregular-shaped LED displays — sphere screens, circular rings and creative architecture. It distributes one 4K-class signal to receiving cards with non-rectangular load partitioning, driving up to 7.8 million pixels in any horizontal or vertical tiling configuration.
Q2 How many pixels can the B1200S drive on a sphere screen?
Up to 7.8 million pixels across 12 gigabit Ethernet ports. Each port carries up to 655,360 pixels in the 1280×512 per-port format, the canvas runs 640–7,680 pixels wide and 480–4,096 high in default mode, and offset reaches 7,680 × 4,095 pixels.
Q3 What video inputs does the B1200S sphere LED controller support?
HDMI 2.0 and DP 1.2 inputs used one at a time, each up to 3840×2160@60Hz with backward compatibility. With a GPU driving the source, the customizable canvas reaches 7,680 pixels wide and 4,096 high. A 3.5mm audio input synchronizes sound over the network cable.
Q4 What is Genlock and why does a sphere controller need it?
Genlock locks multiple devices to one sync source so their video frames advance together. The B1200S offers an optional Genlock interface with one input and one loop-through output — essential when several controllers drive one large sphere or facade and a visible split would appear between zones without it.
Q5 Does the B1200S support 3D LED display?
Yes. The B1200S supports 3D display including active 3D: its 3D interface connects to the 3D transmitter, enabling alternating-frame 3D content on compatible sphere and attraction screens. The controller accepts 30/50/60/120 Hz input frame rates, and the full 3D chain must support the mode together.
Q6 What is Ethernet loopback backup on the B1200S?
If one gigabit output segment on the sphere fails, the data path loops back through the remaining network ports so panels on the failed segment keep displaying. It is Mooncell’s cable-level protection — valuable on curved structures where long runs hide inside the steelwork and are hard to replace quickly.
Q7 What is dual-master backup on the B1200S?
Dual-master backup keeps a second B1200S as hot standby. If the active controller fails, the standby takes over the whole sphere or ring — the configuration exhibition venues and permanent creative installations specify to keep shows on schedule. It requires pricing the second unit from day one.
Q8 What does the F5 setting on the B1200S do?
F5 controls the canvas height limit. With F5 enabled — the factory default — input height is limited to 4,096 pixels; with F5 disabled the height limit rises to 8,192 pixels. The width limit stays 7,680 in both cases, and the mode is chosen to match the unfolded sphere canvas.
Q9 Can the B1200S be controlled by a central system?
Yes. RS232 connects the B1200S to central control equipment, while USB-B lets multiple sending controllers be controlled from a single PC and a 100M LAN port serves host debugging. The front 320×240 LCD with rotary knob handles local configuration, including offline brightness adjustment.
Q10 What frame rates does the B1200S accept?
The B1200S is compatible with 30Hz, 50Hz, 60Hz and 120Hz input frame rates, covering broadcast regions and PC workflows. The 120Hz path also supports active-3D operation, where alternating frames serve each eye at high refresh.
Q11 B1200S vs MTB2000E — which sending controller fits my project?
Choose the B1200S for sphere, ring and other irregular canvases up to 7.8M pixels, especially with Genlock or 3D needs. Choose the MTB2000E for rectangular and perimeter walls up to 10.4M pixels with 20 ports. Both share the 4K60 input bank and the loopback plus dual-master reliability stack.
Q12 How much does the B1200S cost and what is in the box?
Pricing depends on quantity, the optional Genlock board, backup units and the 3D chain; contact Excelled with your unfolded canvas for a factory-direct quote. The box includes the B1200S, power cord, USB cable, HDMI cable, DP cable and certificate, one unit per box at 3.47 kg net.
