What is included? Power cord, USB cable, DVI cable, HDMI cable and certificate of conformity — with factory-direct pricing from our sales team.
When to Buy a Separate LED Sending Controller Instead of a 2-in-1 Processor
Video processors do windows and scaling; sending controllers turn one clean video signal into the per-panel data streams the receiving cards need. If your signal chain already ends at a clean single-source output — from a switcher, a media server, or a content PC — a dedicated sending controller like the MTB400E delivers the drive without paying for a processor you would not use.
Separate sending controllers also earn their place where uptime is the spec: because the sending stage is a standalone box, integrators can run dual-master backup — two MTB400E units, one hot — and swap the box without touching the processing chain. That is harder to arrange when processing and sending are fused in one 2-in-1 unit.

MTB400E Interfaces: HDMI 1.4, DVI, Audio and Four Gigabit Output Ports
Inputs stay deliberately simple because the MTB400E’s job is clean transmission: 1× HDMI 1.4 accepting 4K sources up to 3840×2160@30Hz, 1× DVI up to 1920×1200@60Hz, and a 3.5mm audio input whose audio is synchronized over the network cable — note that audio is carried only via output port P1. Source selection and status live on front-panel buttons and indicators; the front panel even shows the current brightness on its digital display.
| Interface | QTY | Capability |
|---|---|---|
| HDMI 1.4 input | 1 | Up to 3840×2160@30Hz, backward compatible, EDID managed. |
| DVI input | 1 | Up to 1920×1200@60Hz. |
| Audio in | 1 | 3.5mm; synchronized with video over the network cable (audio via output port P1). |
| Gigabit outputs | 4 | Ports 1–4; up to 2.6M pixels total; Ethernet loopback backup between ports supported. |
| Control | 2 | USB-B (PC software; multiple sending controllers cascaded on one PC) + 100M LAN debug port. |
| Extension | 4 | UART IN/OUT serial, 3D transceiver interface, SENSOR light sensor interface, INC inspection key; ST_EXT expansion board support. |
Four Gigabit Ports, 2.6M-Pixel Canvas and Per-Port Load Rules
The MTB400E arranges its 4 gigabit ports in any horizontal or vertical tiling. Each port carries a maximum of 655,360 pixels in a 1280×512 load format; overall load is capped at 2.6M pixels with width between 128–4,096 and height between 64–4,096, and the image offset is adjustable up to 4,095 pixels in either direction — useful when the source canvas is larger than the screen section this box feeds.
| Load Parameter | MTB400E Specification |
|---|---|
| Output ports | 4 × gigabit Ethernet, any tiling direction |
| Max total load | 2.6 million pixels |
| Load range | Width 128–4,096 px; height 64–4,096 px |
| Offset range | 0–4,095 px (width and height) |
| Input frame rates | Compatible with 30 / 50 / 60 / 120 Hz sources |
Ethernet Loopback Backup and Dual-Master Backup: Built for Uptime
Commercial walls rarely forgive downtime. The MTB400E therefore ships with Mooncell’s Ethernet loopback backup — if one network segment fails, the signal loops back through the remaining ports — plus dual-master controller backup, where a second MTB400E stands ready and takes over the wall. For many integrators this redundancy pair is exactly why they buy a separate sending controller rather than a single fused 2-in-1.
Behind the hardware sit the fleet tools: host software monitors sending-card operating parameters and status, configuration can be read back, and gigabit Ethernet error-rate detection flags a degrading cable before it becomes a black zone. The front-panel INC key starts an inspection pass on demand.
Daytime-to-Night Brightness: Display, Sensor and Expansion Board
Screen brightness is a commercial wall’s most-touched setting — so Mooncell gave the MTB400E three ways to handle it. The front digital display shows the current brightness value at a glance; a SENSOR interface accepts a light sensor for automatic brightness adjustment; and ST_EXT expansion board support adds cascaded brightness control plus automatic brightness across multiple sending stages, so an entire mall or campus of walls follows the ambient light together.
Where the MTB400E LED Sending Controller Fits
Commercial Fixed Walls: Redundancy Without a Second System
Retail chains, lobbies and transport signage run 12–16 hours a day. Ethernet loopback plus dual-master backup means a failing port or unit does not mean a dark screen, and remote software monitoring catches drift before it is visible.
Rental & Multi-Unit Walls: Cascaded Control on One PC
Rental rigs combine several 2.6M-class screen blocks. USB cascading lets one PC control multiple MTB400E sending controllers, keeping every block of a large rental canvas addressable from one seat — with config readback so every rig returns to spec after a show.
Content-Loop Installations: Simple Chain, No Processor Cost
When a wall runs one HDMI or DVI source — a player, a PC, a signage box — the MTB400E is the entire chain from source to screen: no processor, no extra box, one clean signal path with audio over P1.

MTB400E LED Sending Controller Buying Guide: 5 Checks Before You Order
- Confirm the load plan fits. Wall width × height must sit under 2.6M px with width 128–4,096 and height 64–4,096 — and remember each of the 4 ports takes max 655,360 px in a 1280×512 per-port load.
- Know your source ceiling. HDMI 1.4 tops at 4K@30Hz and DVI at 1920×1200@60Hz — perfect for players and signage PCs. Native 4K60 content needs the MTB2000E’s HDMI 2.0 / DP inputs.
- Decide the redundancy level. Loopback backup protects a failing cable segment; dual-master backup means buying a second unit. For mission-critical walls price both; for ordinary signage, loopback alone often suffices.
- Plan brightness automation. If the wall faces daylight, budget the SENSOR light probe or the ST_EXT expansion stage early — retrofitting auto brightness after install costs a site visit.
- Verify receiving cards and control workflow. Confirm your receiving card range matches Mooncell drive, and that your integrator uses the USB multi-card cascade — it changes how many PCs a multi-wall project needs.
Price and Cost Factors
As a pure sending controller, the MTB400E undercuts 2-in-1 processors with comparable drive — you pay for transmission and reliability, not windowing. Price drivers: order quantity, a second unit for dual-master backup, light sensors/expansion boards, and pre-terminated network bundles for the 4 ports. Ask for a quote on the whole drive chain including receiving-card counts.
MTB400E LED Sending Controller FAQ
Q1 What is the MTB400E LED sending controller?
The MTB400E is Mooncell’s 4-port LED sending controller: it takes one video signal — HDMI or DVI — and distributes it to LED receiving cards over gigabit Ethernet, driving up to 2.6 million pixels. Unlike a 2-in-1 video processor it does no windowing or scaling; it is the clean, reliable sending stage between a processed source and the screen.
Q2 How many pixels can the MTB400E drive?
Up to 2.6 million pixels total across 4 gigabit Ethernet output ports. Each port carries a maximum of 655,360 pixels in a 1280×512 per-port load format, the canvas can run 128–4,096 pixels wide and 64–4,096 tall, and the output tiles in any horizontal or vertical configuration.
Q3 What video inputs does the MTB400E sending controller have?
One HDMI 1.4 input accepting sources up to 3840×2160@30Hz with EDID management, and one DVI input up to 1920×1200@60Hz. There is also a 3.5mm audio input; audio is synchronized with the video over the network cable and carried by output port P1 to the receiving side.
Q4 What is Ethernet loopback backup on the MTB400E?
Ethernet loopback backup is Mooncell’s cable-failure protection: if one gigabit output segment fails, the signal path loops back through the remaining network ports so the affected panels keep receiving data. It protects against a single failed cable or port without requiring a second controller.
Q5 What is dual-master controller backup?
Dual-master backup pairs a second MTB400E as a hot standby for the active controller. If the primary unit fails, the standby takes over the screen — the classic redundancy configuration for mission-critical commercial walls. It is why many integrators choose a separate sending controller over a single fused 2-in-1 unit.
Q6 Does the MTB400E support automatic brightness control?
Yes, three ways. The front panel shows the current brightness value on a digital display; a SENSOR interface accepts a light sensor for automatic brightness adjustment; and ST_EXT expansion board support adds cascaded brightness control plus automatic brightness across multiple sending stages — useful for whole-facility lighting programs.
Q7 Can one PC control several MTB400E units?
Yes. The MTB400E provides USB-B communication, and multiple sending controllers can be cascaded and controlled from the same PC — the standard workflow for rental rigs and multi-wall sites where each screen block has its own MTB400E. A 100M LAN port is available for host debugging.
Q8 What monitoring does the MTB400E offer integrators?
The host software monitors sending-card operating parameters and status, supports configuration parameter readback, and performs gigabit Ethernet error-rate detection — so a degrading cable or drifting setting is caught remotely before it becomes a visible fault. The front INC key starts an on-site inspection pass.
Q9 Does the MTB400E support 3D LED display?
The MTB400E carries a 3D transceiver communication interface on its extension bank, positioning it for 3D transceiver hookups in supported system chains. For fully documented active-3D display drive, the MTB2000E lists active 3D support directly in its specification; check your receiving-card and panel chain for 3D compatibility.
Q10 What source frame rates does the MTB400E accept?
The MTB400E is compatible with multiple input frame rates including 30Hz, 50Hz, 60Hz and 120Hz, which covers PAL/NTSC regions and both cinema-style and PC refresh workflows. Resolution and EDID are managed per connected source.
Q11 Is the MTB400E the right choice, or do I need a video processor?
If your chain is one clean source feeding one LED wall, the MTB400E is the entire drive stage. If you need to switch, scale or layer several sources into windows, keep a video processor upstream — or choose a 2-in-1 unit like the Mooncell MVB4S Pro that fuses processing and sending in one box.
Q12 How much does the MTB400E cost and what is in the box?
Pricing depends on quantity, redundancy configuration and cable bundles; contact us for a factory-direct quote. The box includes the MTB400E, power cord, USB cable, DVI cable, HDMI cable and certificate of conformity, packed 3 units per carton; net weight is 2.83 kg.
