MTB400E LED sending and backup control
The Mooncell MTB400E receives DVI or HDMI video and transmits display data through four Gigabit Ethernet outputs. Its stated 2.6-million-pixel capacity and backup functions support LED screen control for stages, conferences, events and exhibitions. USB communication allows multiple sending cards to be managed from one computer.
The existing specification download has a model-label inconsistency: its cover and overview name MTB400E, but the later technical pages name MTB400S. The table uses the original product page and the clearly identified MTB400E feature section. Later electrical and mechanical specifications have not been silently reassigned to MTB400E.
Technical specifications
| Parameter | Specification |
|---|---|
| Model | Mooncell MTB400E master controller / LED sending enclosure |
| Video inputs | 1 × DVI and 1 × HDMI |
| Audio | 1 audio input, with synchronous network-cable transmission |
| LED outputs | 4 Gigabit Ethernet outputs |
| Total capacity | 2.6 million pixels |
| USB communication | USB control; multiple sending cards can be cascaded to one computer, according to the MTB400E feature section. |
| Backup | Ethernet-port loop dual backup and dual master-controller backup |
| Preset resolutions | 1024 × 768, 1280 × 1024, 1366 × 768, 1600 × 1200, 1920 × 1080, 2048 × 1152 and 2560 × 960; custom resolution supported |
| Frame rates | 30, 50, 60 and 120 Hz compatibility is listed; the source does not pair every rate with each resolution. |
| Monitoring | PC software monitoring of sending-card operating parameters/status; Gigabit network error-rate detection |
| Configuration readback | Supported |
| Optional expansion | The MTB400E feature section lists an optional ST-EXT expansion panel for cascade control and automatic brightness adjustment. |
| Document-model discrepancy | The PDF cover and overview identify MTB400E, while its later parameter, interface and electrical pages are headed MTB400S. Values unique to those later pages are not presented as confirmed MTB400E specifications. |

Frequently asked questions
What is the MTB400E loading capacity?
The original listing and MTB400E overview in the PDF both state a maximum total of 2.6 million pixels through four Gigabit Ethernet outputs.
Which sources can connect to MTB400E?
The listing specifies one DVI video input, one HDMI video input and one audio input. Verify the exact source timing for your installation; a general frame-rate compatibility list does not establish every resolution/rate combination.
Can MTB400E provide redundant transmission?
The MTB400E feature section lists Ethernet-port loop dual backup and dual master-controller backup. Plan the required cabling and second controller according to the installation configuration.
Does automatic brightness adjustment require an expansion panel?
The MTB400E section identifies the ST-EXT panel as an optional accessory for cascade control and automatic brightness adjustment. It does not establish that this panel or a sensor is included.
Why are voltage and dimensions not confirmed in this table?
The existing PDF starts as an MTB400E document but labels its later technical pages MTB400S. The download is retained, but electrical ratings and dimensions from those pages require model-specific confirmation before they are applied to MTB400E.
