ADLINK NuPRO-770 Full length SBC Configuration and Maintenance

ADLINK NuPRO-770 Series PICMG Full Length Card SBC: A Complete Guide to Architecture Configuration and Engineering Maintenance

In the field of industrial computers, Full size SBC has long occupied a core position in high-end industrial control and telecommunications applications due to its excellent scalability, good heat dissipation structure, and strict adherence to PICMG standards. The NuPRO-770 series launched by ADLINK is a representative full-length card product based on the Intel Socket-370 processor and i82810 chipset. This series supports Intel Celeron and Pentium III FC-GGA processors, with onboard integrated VGA controller, 10/100Mbps Ethernet (NuPRO-770 only), dual EIDE channels (supporting Ultra DMA/66), high driver ISA bus (64mA), and embedded hardware monitoring and programmable watchdog timer, providing a computing platform that combines performance and reliability for harsh industrial environments.

Although NuPRO-770 is no longer the latest product, there are still a large number of equipment in service in numerous automated production lines, rail transit, and military systems. Mastering the hardware configuration, jumper settings, BIOS tuning, driver deployment, and watchdog programming details is of great significance for system maintenance, rapid fault location, and extending equipment service life. This article is based on the official user manual and systematically outlines the core specifications, installation steps, key jumpers, serial port mode selection, VGA/network card driver installation, watchdog programming, and hardware monitoring applications of NuPRO-770 (and the same series NuPRO-771), providing on-site engineers with a highly operational technical reference document.

Product series overview and model differentiation

The NuPRO-770 series includes two main models:

NuPRO-770: Standard model, onboard Intel 82559 10/100Mbps Ethernet controller, supports Wake On LAN and optional Alert on LAN II.

NuPRO-771: Similar to 770, but without onboard network interface, suitable for applications that do not require a network or require the use of independent network cards.

The two models are highly consistent in terms of jumper, BIOS, and driver installation, and can be considered as the same platform except for the network part.

Core hardware architecture and technical characteristics

1. Processor and chipset

CPU socket: Socket-370, supports Intel Celeron (PPGA/FC-GGA) and Pentium III FC-GGA processors, external frequency 66/100 MHz, with built-in L2 cache in the CPU.

Chipset: Intel i82810 (810) integrated chipset, including AGP 2X graphics controller (supporting dynamic shared system memory as video memory, adjustable from 1 to 11 MB), and integrated 230 MHz RAMDAC, with a maximum CRT resolution of 1600 × 1200@8bpp (85Hz refresh rate).

Memory: Two 168 pin DIMM slots, supporting PC-100 non buffered SDRAM, with a maximum capacity of 512 MB (up to 256 MB per pin). The official statement clearly states that the i82810 chipset does not support PC-133 SDRAM, please make sure to use the PC-100 specification to ensure stability.

2. Storage and I/O

EIDE: Dual channel (Primary and Secondary), supports PIO Mode 3/4 and Ultra DMA/66, can connect up to four IDE devices (hard drive, optical drive, LS-120, ZIP, etc.). The 20 pins of the Primary IDE connector (CN1) provide+5V power and can directly support DiskOnModule (DOM flash drive).

FDD: Single floppy drive interface, supporting 360KB~2.88MB.

Serial port: COM1 (CN6) is RS-232; COM2 (CN5) can select RS-232, RS-422 or RS-485 (default RS-232) through jumper, with ESD protection of 2KV.

Parallel port (CN3): Supports SPP/EPP/ECP mode, ESD protection 4KV, downstream equipment protection 30V.

USB: Two USB 1.1 interfaces (via 8-pin pins) with independent overcurrent protection.

PS/2: The keyboard (CN17) and mouse (CN16) have independent Mini DIN pins, and an internal keyboard interface (CN13) is also provided.

3. Network (NuPRO-770 only)

Intel 82559 Fast Ethernet Controller, 32-bit PCI bus master, supports 10/100Mbps adaptive, full duplex, flow control, Wake On LAN (requires ATX power supply+5VSB). Onboard RJ-45 connector (CN14) with dual color LED indicating link and speed.

4. High driving capability of ISA bus

The ISA bus of NuPRO-770 provides up to 64mA driving capability on all data, address, and control lines, which is crucial for driving ISA expansion cards with high loads such as data acquisition cards and motion control cards, avoiding signal distortion or system instability caused by insufficient driving of traditional ISA buses.

5. Hardware monitoring

Monitoring IC: Winbond W83627HF (Super I/O chip with built-in hardware monitoring function).

Monitoring items: CPU temperature, system temperature (via CN10 external thermistor), CPU fan speed, chassis open status (JP6), system voltage (VCORE,+3.3V,+5V,+12V, -12V,+5VSB).

Supporting software: Hardware Doctor (supports Windows 98/NT), can set alarm thresholds, pop up warnings and emit beeps when exceeded.

6. Watch dog timer

Based on logic device 8, the CRF5/CRF6/CRF7 registers have programmable timeout values ranging from 0 to 255 seconds or minutes.
