General Specifications:  2 panel sizes: * 500x500 (128x128 pixel dimensions) * 500x1000 (128x256 pixel dimensions) 208v power only  A5s receiving cards Powercon in/out (power in hardwired, non-removable whip) Seetronic data in/out (standard RJ-45 connectors, OR seetronic locking connectors, ethercon DO NOT work) Indoor use (not water-resistant, or high enough NIT/brightness for outdoor use) Hot-swappable front service, magnet mounted modules with backup retainer screws manufacturer link: http://prestigeledscreens.com.au/an-series/ [http://prestigeledscreens.com.au/an-series/] Quantities: (QC methodology/criteria/notes listed below) * 500x1000 Total panel count: 90 (18 cases, 5/ea) * 500x1000 QC passed count: 85  (4 cases NIB sealed factory packaging, did not test these) * 500x1000 QC Fail count: 5 * 500x500 total panel count: 40 (4 cases, 10/ea) * 500x500 QC passed count: 40 (3 cases NIB sealed factory packaging, did not test these) * 500x500 QC FAIL count: 0 * Spare LED modules: 0  * Spare PSUs: 0 * Spare receiving cards: 0 * Spare frames/main boards: 0 QC methodology/notes: Methodology: 1. Each panel was connected to power and data in/out to test all ports. R/G/B/W test patterns were transmitted to determine LED condition, as well as a fast moving video file to test for ghosting or receiving card issues.  2. 100% led integrity is nearly impossible to maintain for a working inventory wall. For Pass/Fail, I used the “20 foot in white” criteria. If there was a noticeable issue from 20 feet away with the display set to white, such as a cluster of multiple LEDS stuck/damaged/dead, it failed.  3. QC pass conditions:  bad pixels scattered thru panel, all data/power ports functional 4. QC fail conditions: 5 or more bad (damaged/missing, stuck, dead, etc) in a cluster that is noticeable from 20 feet away with display set to white. Also any receiving card or port issues automatically fail.  Notes: 1. QC notes: the vast majority (80+ %) of the panels have 3-5 scattered bad pixels, whether that’s completely dead, one color dead, or missing. 2. The panels tagged as QC FAIL generally only have one bad/damaged module. One main board/receiving card was nonfunctional, and is tagged with this info.
