VGA rear DB15 standard interface only has internal pins, no rear panel interface

Parallel port rear DB25 with only reserved pins inside the board

14 slot backplane compatibility not supported, PCI bus conflict risk

Universal storage: dual UDMA33 IDE, floppy drive FDD; COM2 supports RS232/422/485 hardware jumper switching.

Core Hardware Functional Specifications

(1) Bus and Expansion

Follow PICMG2.0 (cPCI), PICMG2.1 (hot swappable), PICMG2.7 (dual system bus)

Single 32-bit PMC expansion slot, default IO voltage 5V, can be changed to 3.3V; dual PCI2050 bridge supports up to 14 bus master control peripheral slots

CPCI Gold Finger J1/J2/J3/J4/J5 complete signal definition, supporting dual I/O routing in front and back

(2) Storage system (choose one, cannot be used simultaneously)

Onboard DB-6760CF daughter card: Type-II CF card, occupying the second IDE channel, jumper set to master/slave

2.5-inch ultra-thin 9.5mm ATA hard drive: Same IDE channel, installation requires copper pillar accessory package

Rear RTM provides dual 40Pin IDE and 34Pin floppy drive interfaces, which can be connected to external optical/DOM electronic drives

(3) Peripheral interface (choose one of front and rear routing, prohibit simultaneous wiring)

Display: SM721 AGP2X graphics card, up to 1280 × 1024 @ universal across the entire system, NT customization can be 1600 × 1200; VGA can be pulled out both front and back

Serial port: COM1 fixed RS232; COM2 hardware jumper switch RS232/422/485/automatic transmission and reception 485+

USB: 2-channel USB 1.1, divided into front A port and rear A port, with overcurrent protection every time

Network port: Dual Intel 82559, supports PCIe diskless boot and network card aggregation (fault-tolerant/load balancing/link aggregation); On board dialing switch network port, whether to use the front panel or the back panel

PS/2 keyboard and mouse: front composite Y-shaped cable interface, rear independent keyboard and mouse port

Parallel port: SPP/ECP/EPP, 4KV ESD protection

(4) Industrial reliability function

Watchdog WDT: 1 second/1 minute step, timing from 0 to 255, automatic restart upon timeout; Amber LED status indicator on the front panel, providing DOS/Windows development library

Hardware monitoring W83782D: collects CPU temperature, system temperature, CPU fan speed, ± 5V/± 12V/3.3V core voltage, matched with Hardware Doctor monitoring software

Self Hot Swap: The blue LED on the front panel allows for a soft shutdown and safe unplugging after turning on the handle switch, following PICMG2.1 specifications; The motherboard itself is a system slot and does not support live plugging. It only supports hot plugging in the peripheral slot

Chassis lid opening detection, buzzing alarm, BIOS boot password, remote serial port console redirection

(5) Environment and power consumption

Working temperature 0~60 ℃ (P7 requires 6CFM air cooling, P8 requires 10CFM forced air cooling); Storage -20~80 ℃

Vibration: Running at 0.5Grms (with hard drive), idle at 1.88Grms; Impact 15G peak

Certified CE/FCC B-level, passed HALT temperature vibration accelerated aging test

Front panel LED and buttons

Green power LED: always on when powered on

Red IDE light: Disk read/write flashing

Amber WDT light: watchdog enabled continuously flashing

Blue hot swappable light: allows constant illumination when unplugging the board

Reset button, hot swappable control micro switch; The network port comes with a speed amber light and a link green flashing light

Chapter 2: Definition of Jumpers, Connectors, and Pins

Front end motherboard key jumper JP1

JP1 controls CMOS: 2-3 short circuit as default normal; Short circuit 1-2 to clear BIOS settings.

Network Port Routing Dialing S1/S2/S3/S4

At the bottom of the motherboard, there are four sets of micro dials that control LAN1 and LAN2 to use the front panel RJ45 or rear RTM respectively; Prohibiting a group of dialing codes from being turned on simultaneously can cause the network card to short circuit and fail.

Distinguishing jumper wires between two RTM adapter boards

CPCI-R6760D: JP2~JP5 four sets of jumpers, switch COM2 level standard (232/422/485/485 automatic transmission and reception)

CPCI-R6760S: JP2/JP3 controls LAN3/LAN4 enablement; JP4~JP7 switch COM2 level

Complete Pin List for All Interfaces

The document includes all panel interfaces (VGA, COM, Ethernet, etc.) USB、PS2、 Parallel mouth SCSI）、 Complete pin signal definitions for the in board pins (IDE/FDD, cPCI rj3/rj4/rj5, PMC J11/J12), and accompanying engineering drawings for the top/bottom layer of the board and RTM board layout.

Important wiring ban

The same function (VGA/Ethernet/serial/keyboard and mouse) cannot be wired simultaneously on the front and rear panels, which will burn out the interface and lose warranty.

Chapter 3 Installation Operation Guide

Memory installation

Dual 144Pin SO-DIMM slots, supporting 32/64/128/256MB PC100 3.3V memory, with a maximum of 512MB; after installation, it should not be raised above the board height to avoid component damage caused by squeezing when inserted into the chassis.

CF clip card DB-6760CF

Replace the onboard 2.5-inch hard drive and install it on the CN2 44Pin second IDE of the motherboard

JP1 jumper setting for master/slave devices, IDE channel can mount up to 2 devices, rear IDE hard drive needs to have a slave disk to avoid conflicts

Equipped with pop-up buckles and shock resistant fixing screws, suitable for replacing mechanical hard drives in high vibration scenarios

Installation of 2.5-inch hard drive

Special 44Pin ribbon cable+copper pillar accessory package; Only supports 9.5mm ultra-thin disks, CF/solid-state electronic disks are recommended as substitutes for high vibration environments.

Chassis and Backpanel Adaptation

Linghua original cBP-6108/6105/6515/6402 backplane: J3/J5 directly connected to IDE/FDD, can be directly connected to storage without RTM

Third party non-standard backplane: Must be paired with corresponding RTM adapter board to use rear I/O

IDE channel master-slave specification: Front mounted CF/hard drive defaults to master drive, rear mounted IDE devices must have a slave drive, otherwise conflicts will be recognized

Chapter 4 Driver Installation Tutorial

Supporting driver CD support systems: Win95/98/ME, NT4.0, Win2000, Linux, VxWorks, divided into three types of core drivers. Step by step instructions:

SM721 graphics card driver

Win2000/98 direct device manager update; NT4 must be patched with SP4 or above before AGP can be enabled, with a standard resolution of 1280 × 1024.

Intel 82559 Network Card Driver

Support network card load balancing, fault redundancy, and link aggregation; NT requires creating a driver floppy disk before installation, and providing Netware and Linux supporting files.

LSI 53C1000R SCSI driver (only compatible with R6760S)

Ultra160 external SCSI, when installing the NT system, it is necessary to load a floppy disk driver to recognize the SCSI hard disk.

Addendum: The system comes with UDMA IDE drivers that do not require manual installation.

Chapter 5 Watchdog, Supporting Tools, and Advanced Features

Watchdog WDT Development and Testing

IO address 0x3F0 configured with W83977EF Super IO, timing range of 1 second to 255 minutes, write 0 to turn off

The CD provides DOS/Win98/NT testing programs and development libraries, which can be embedded with industrial control software to achieve automatic reset of system crashes

Hardware Doctor Hardware Monitoring Tool

Windows platform backend resident software, real-time monitoring of voltage, fan, and temperature; Exceeding the limit pop-up window+buzzing alarm, custom threshold to prevent overheating and burning of CPU/power supply.

PCIe Network Disk Free Startup

The dual network port supports a PXE pre boot environment, and when paired with DHCP+TFTP servers, it can load the operating system from the local area network, making it suitable for devices without local storage.

Network card adapter aggregation (Adaptive Teaming)

Four working modes: fault tolerance, adaptive load balancing, fast Ethernet channel, standard link aggregation, to enhance bandwidth and network redundancy.

PICMG2.1 Hot Plug Mechanism

ENUM # interrupt signal notifies motherboard peripheral insertion and removal, BIOS can configure IRQ3/9

Insertion and unplugging process: toggle the hot plug switch → system soft shutdown → blue light stays on for safe unplugging; Plug in board automatically re enumerating PCI hardware

Limitation: cPCI-6760D is the system main control slot and hot plugging is prohibited for itself. Only sub peripheral slots support hot plugging
