Frequently asked questions
What is the documented HD-R732 loading range?
The retained specifications list 256 × 1024; the English PDF gives 262,144 pixels. Check the module arrangement against the specification before assigning the load.
Does the R732 use HUB75E or HUB320?
The card has 8 HUB320 interfaces. Match the module connector and pin definition before selecting it.
Which scan modes are supported?
The specification lists static through 1/128 scan. Driver-chip and module compatibility still need to be checked for the installation.
Can it connect to synchronous and asynchronous sending systems?
The PDFs list dual-mode playback boxes, asynchronous controllers, synchronous sending cards and video processors as sending-device types.
What voltage does the receiving card require?
The specified input is DC 4.0–5.5V. The PDFs recommend a standard 5V power supply for stable operation.
