A7s Plus Setup and Service Reference
The NovaStar A7s Plus connects to a cabinet hub board through high-density connectors. This page focuses on setup, status indicators and the original V1.1.2 specification dated July 30, 2021. The card provides up to 32 parallel RGB data groups or 64 serial data groups, expandable to 128.
| Parameter | Specification |
|---|---|
| Maximum loading capacity | 512 × 512 pixels; NovaLCT V5.3.1 or later required |
| Input voltage | 3.3–5.5 V DC in V1.1.2 |
| Rated current / power consumption | 0.6 A / 3.0 W |
| Dimensions / net weight | 70.0 × 45.0 × 7.9 mm / 17.4 g |
| Operating conditions | −20°C to +70°C; 10–90% RH, non-condensing |
| Storage conditions | −25°C to +125°C; 0–95% RH, non-condensing |
| Mated card-to-hub outer-surface distance | 5.0 mm; 5 mm copper pillar recommended |
Revision differences: The later V1.2.5 document lists a 3.8–5.5 V input range, 8.3 mm overall height and −40°C to +85°C storage range. It separates PWM loading of 512 × 512 @ 60 Hz from common-IC loading of 512 × 384 @ 60 Hz. The V1.2.1 change history also removes LVDS transmission. Do not transfer the older reference values or feature list to a different revision without checking the supplied card.
Reading the Status LEDs
| Parameter | Specification |
|---|---|
| Green flashes once every 1 second | Normal operation, normal Ethernet connection and available video input |
| Green flashes once every 3 seconds | Abnormal Ethernet connection |
| Green flashes 3 times every 0.5 second | Ethernet connection normal, but no video input |
| Green flashes once every 0.2 second | Application program did not load; backup program is in use |
| Green flashes 8 times every 0.5 second | Ethernet redundancy switchover; loop backup has taken effect |
| Red power LED stays on | Power input is normal |
Configuration and Module Checks
Use mapping to identify the receiving-card number and Ethernet port on each cabinet. NovaLCT V5.2.0 or later is required for the documented firmware readback, bit-error detection and dual-card status monitoring. Readback can save the existing configuration to a computer before service work.
RGB Gamma adjustment requires a supporting sending card and NovaLCT V5.2.0 or later. 3D requires a 3D-capable sender. Smart-module functions need dedicated firmware, while module Flash calibration requires modules that contain flash memory.
V1.1.2 includes pixel-level brightness and chroma calibration, color management, 18bit+, 90° rotation and dual backup of calibration coefficients. Consult the original pin diagrams when checking hub-board wiring.
Frequently Asked Questions
Which NovaLCT version is specified for the 512 × 512 load?
The original V1.1.2 introduction requires NovaLCT V5.3.1 or later for its stated maximum load. Later documents add driver-IC-specific loading limits.
What does a green flash every three seconds mean?
In the V1.1.2 indicator table, it means the Ethernet cable connection is abnormal.
Why does the green LED flash three times every half-second?
That pattern indicates a normal Ethernet connection but no available video source input.
What does a green flash every 0.2 seconds mean?
The card did not load the application-area program and is using the backup program.
Should I use the old or new voltage range for a replacement?
Match the supplied card revision and its applicable specification. V1.1.2 lists 3.3–5.5 V, while V1.2.5 lists 3.8–5.5 V; these references should not be treated as interchangeable.
