ADLINK NuPRO-852 LGA775 Industrial Control Motherboard Maintenance Guide

2-3 Short circuit clearing of CMOS content

When the BIOS settings are incorrect and cannot be started, short circuit pins 2-3 of JBAT1 for about 2 seconds after power off, restore them to pins 1-2, and then power on again to restore the factory BIOS settings.

3.3 Clear BIOS Password (JPWD1)

JPWD1 setting function

1-2 Short circuit normal operation (default)

2-3 Short circuit clearing BIOS password

When forgetting the supervisor or user password, short circuit pins 2-3 of JPWD1 to clear the password setting.

Chapter 4: Detailed Explanation of Key Interfaces and Connectors

4.1 Front panel connector (JFP1)

JFP1 has a 20 pin needle arrangement and integrates all control signals from the front panel

Pin group signal function

Power LED (1-3-5-7)+5V, PLED power indicator light (Pin5 for signal, Pin1 for+5V)

ATX power supply (9-11-15-17) GND, PWRONT ATX soft switch control

Chassis speaker (2-4-6-8-11-13) SPKS, GND buzzer output

Reset button (10-12) RESETBT, GND hardware reset

Hard drive LED (14-16) HDLED,+5V hard drive activity indicator

Power button (18-20)+5VSB, PWRBT power button

4.2 Power Connection

ATX 12V power supply (JPW1): 4-pin+12V auxiliary power supply interface, must be connected, otherwise the CPU cannot obtain sufficient current and the system cannot start.

ATX main power supply: obtained from the backplane through a gold finger.

4.3 IDE and SATA storage interface

IDE1 (ATA133): 40 pin IDE interface, supports PIO Mode 0-4 and Ultra DMA 66/100/133. When connecting two IDE devices, a master/slave jumper needs to be set.

SATA1/SATA2: SATA II interface, data rate of 300MB/s, fully compatible with Serial ATA 2.0 specification. Important reminder: "Please do not fold the Serial ATA cable into a 90 degree angle. Otherwise, data loss may occur during transmission." Do not bend the SATA cable 90 degrees, as this may result in data transmission errors.

4.4 Other I/O interfaces

COM1/COM 2: 16550A serial port, supports 16 byte FIFO. COM1 is configured in RS-232/422/485 mode through three sets of jumpers (JP1/JP2/JP3).

F_USB1/F_USB2: Two USB 2.0 pin sockets, supporting 480Mbps high-speed transmission.

J1 (parallel port): 26 pin arrangement, supports SPP/EPP/ECP mode.

JAUD1 (Front Panel Audio): 14 pin audio pin layout (optional), supports front audio I/O.

JRT1: Temperature sensor interface, which can be connected to an external thermal probe to monitor the temperature of the system.
