3. Operating Instructions
Electrostatic Discharge (ESD) Protection: Wear an antistatic wrist strap connected to earth ground before handling the board.
CPU & Cooler Installation: Open the LGA1155 socket lever, insert the CPU aligned with the orientation keys, latch the lever down, and apply thermal grease before securing an industrial CPU cooler.
Memory Installation: Insert unbuffered DDR3 1333/1600 MHz DIMM modules into slots starting with DIMM_A1. Press firmly until the retaining clips snap into place.
Power Supply Connection: Connect standard 24-pin ATX power and 4-pin 12V CPU power cables from an industrial PSU.
Jumper Configuration: Set COM port operating mode jumpers (RS-232 vs. RS-422/485) prior to system bootup.
4. Fault Diagnosis & Troubleshooting
| Symptom | Likely Cause | Suggested Action |
| No Power / LED Off | Power supply disconnected or standard ATX PSU switch off. | Verify 24-pin and 4-pin ATX power cables; verify power button front-panel header pin connections. |
| Beep Codes / Continuous Beep | Memory seating failure or incompatible DDR3 RAM module. | Reseat DDR3 DIMMs; verify RAM specs (non-ECC, 1.5V DDR3 1333/1600 MHz). |
| No Display Output | Incorrect primary display setting or improper cable connection. | Verify VGA or DVI-D cable seating. Clear CMOS via onboard jumper CLR_CMOS if BIOS settings were modified incorrectly. |
| OS Boot Failure / Blue Screen | SATA mode mismatch (AHCI vs. IDE) or drive cable loose. | Access AMI BIOS setup (Del or F2 on startup) and check SATA mode settings. Verify SATA power and data cables. |
| Watchdog System Reset | Unresponsive software task triggering timer reset. | Check Watchdog application timeout intervals or disable WDT in BIOS during software debugging. |
