ADLINK NuPRO-590 Series Socket7 Industrial Control Motherboard Maintenance Guide

RS-422 5-3-1 / 6-4-2 5-3-1 / 6-4-2 5-3 / 6-4-2

RS-485 5-3-1 / 6-4-2 5-3-1 / 6-4-2 5-3 / 6-4-2

The specific short-circuit combination should refer to the table in the manual. The COM2 pin is defined as DCD/RXD/TXD/DTR/GND/DSR/RTS/CTS/RI in RS-232 mode; The pin functions are different in RS-422/485 mode.

3.2 Watchdog Timer Configuration

The programmable watchdog timer of NuPRO-590 supports 0-255 seconds or minute timeouts, which can be configured through I/O ports 3F0h and 3F1h.

Configure register access process:

Enter extended function mode: Write 87h twice to port 3F0h

Configure registers such as CRF2 (counter) and CRF4 (time unit) for logic device 8

Exit extended function mode: Write 0Ahh to port 3F0h

Assembly code example (15 second timeout, system reset):

text

Enter the extended function mode

MOV DX, 3F0H

MOV AL, 87H

OUT DX, AL

OUT DX, AL

Select logical device 8

MOV DX, 3F0H

MOV AL, 07H

OUT DX, AL

MOV DX, 3F1H

MOV AL, 08H

OUT DX, AL

Set CRF4- Unit second (bit6=1)

MOV DX, 3F0H

MOV AL, 0F4H

OUT DX, AL

MOV DX, 3F1H

MOV AL, 40H

OUT DX, AL

Set CRF2- timeout value of 15 seconds

MOV DX, 3F0H

MOV AL, 0F2H

OUT DX, AL

MOV DX, 3F1H

MOV AL, 0FH

OUT DX, AL

Exit the extended function mode

MOV DX, 3F0H

MOV AL, 0AAH

OUT DX, AL

The watchdog can be triggered by keyboard or mouse interrupts to reload (reset counter), and the application needs to periodically "feed the dog" to prevent system reset.

Chapter 4: LCD Panel Interface and Display Configuration

4.1 Flat panel LCD connector (CN4)

CN4 is a 50 pin dual row pin, supporting DSTN/TFT LCD panels, with a maximum resolution of 1280 × 1024 × 8bpp color depth. The main signals include:

VCLK: Pixel Clock

P0~P33: RGB data signal (supports 12/18/24 bits)

SHFCLK: Shift Clock

FLM (VSYNC): Frame Synchronization

LP (HSYNC): Row Synchronization

ENABKL: Backlight Enable

FPvDD/FPvEE: Panel Power Supply

4.2 Panel Type Selection (BIOS)

In the Power Management Setup of BIOS, select the LCD panel type through the "Panel Type Selectable" field, which supports 16 preset panels:

Option panel specifications

Panel-1 1280 × 1024 TFT color

Panel-2 640 × 480 Dual Scan STN Color

Panel-5 (default) 640 × 480 18 bit TFT color

Panel-6 1024 × 768 TFT color

Panel-7 800 × 600 TFT color

If using a CRT monitor, set "LCD&CRT" to "CRT" or "Both" in the Standard CMOS Setup.

Chapter 5: BIOS Key Configuration Items

NuPRO-590 uses Award BIOS, press Del key to enter Setup when booting up.

5.1 Standard CMOS Setup

LCD&CRT: Select display interface - Auto, Both, CRT only, LCD only

Halt On: Set POST error pause behavior - All Errors (default, pause any non fatal errors), No Errors, All But Keyboard, etc

Hard disk parameters: Supports Auto detection of IDE devices, with optional Type 1 to 45 pre-defined or user-defined

5.2 BIOS Features Setup

Virus Warning: Protect hard disk boot sectors and partition tables, recommended disabled (must be turned off when running disk diagnostic tools)

Boot From LAN First: Start from LAN first after activation (requires cooperation with PXE)

Boot Sequence: Set the boot device sequence, such as A, C, SCSI (default)

CPU Internal/External Cache: It is recommended to enable it to accelerate memory access

Quick Power On Self Test: Enabled can shorten POST time

Security Options: Setup (password required to enter BIOS only), System (password required to boot up and enter BIOS)

5.3 Chipset Features Setup

Power Supply Type: AT (default) or ATX. If using ATX power supply, it needs to be set to ATX to support soft shutdown, modem wake-up, and LAN wake-up
