1. PCB/SKD Assembly: Test & Alignment
1.1.
Pre-Conditions and DC/DC Check
Before power-on, please check the board according to the relevant block diagram and circuit
diagram, and make sure that no serious issue or mistake can destroy the board. For example, the
output of DC/DC and LDO should not be shorted to ground.
Supply a suited voltage and power-on, then check the voltage according to the relevant block
diagram, circuit diagram and voltage spec . the error should less than 5% .For example, the voltage
for main chip(+3V3, AV3.3, +1V2, CORE1V2, etc.), the voltage for DDR (DDRV) , the voltage for
amplifier (AMP_VCC), etc...

1.3. Project ID Modification
There are different IDs stored into the NVM depending on different Panels settings and Models
features, but there’s only one key branching ProjectID that includes all. So, it’s not recommended to
modify Panel ID with Hyper terminal as other ID features may not change!
To modify Project ID, you need to go through “
Design menu

Service menu

Project ID
”, then
spin left or right with RCU “
Zoom±
” keys to suitable ID (Project name is dynamically refreshed).
See Appendix

“
How to change Project ID with RCU
”
Here below is none exhaustive ProjectID table for reference:

1.4. Functional Test
Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected, plug all
external generator devices to relevant inputs/outputs below according to their respective test patterns
