ADLINK NuPRO-780 PICMG Bus Core CPU Card

3. Keyboard/mouse wake-up overload mechanism

The WDT of NuPRO-780 supports a feature: keyboard and mouse interrupts can reload the watchdog timer. When the Bit 7 and Bit 6 of CRF7 registers are set (i.e., the write value is greater than C0h or 192 decimal), any keyboard key or mouse movement event will trigger the reload of WDT. This design is very practical in systems with human-computer interaction interfaces - as long as the operator is still operating the terminal, the system will not reset due to watchdog timeout.

4. Programming points

The configuration of the watchdog timer should follow the standard LPC configuration process:

Write 87h twice to I/O port 2Eh to enter Extended Function Mode.

Configure the relevant registers (CRF5, CRF6, CRF7) of logic device 8 to set timeout values, enable WDT, and configure interrupt response.

Write 0Ahh to I/O port 2Eh and exit the extended function mode.

ADLINK provides sample programs and subroutine libraries for DOS, Windows 95/98/2000, and Windows NT in the accompanying driver CD, making it easy for engineers to integrate quickly.

Rich onboard interfaces and jumper configurations

The NuPRO-780 provides complete I/O interfaces on the front panel and onboard, and its layout and configuration fully consider industrial site requirements:

1. Standard I/O interface

VGA interface (CN2): A standard 15 pin D-Sub interface used to connect a monitor.

Dual RJ-45 Ethernet ports (CN3/CN6): The dual Ethernet port model (DV) provides two standard Ethernet interfaces.

PS/2 keyboard and mouse interface (CN5): With the included Y-shaped distribution cable, both the PS/2 keyboard (purple) and mouse (green) can be connected simultaneously, following the PC'99 standard color scheme. You can also connect the keyboard separately.

USB interface (CN19): Provides two USB 1.1 interfaces, supporting standard USB keyboards, mice, USB drives, and other peripherals, with each port having independent overcurrent protection.

2. Onboard expansion connector

IDE interface (CN14/CN15): Two Ultra/ATA-100 IDE interfaces, supporting up to 4 IDE devices.

Soft drive interface (CN10): Standard 34 pin soft drive interface, supporting various types of soft drives from 360KB to 2.88MB.

Parallel port (CN7): 25 pin D-Sub interface.

Serial port (CN8/CN1): COM1 (CN8) is a 10 pin pin pin interface, and COM2 (CN1) is also a 10 pin pin pin interface, which needs to be led out through the accompanying serial port cable.

IrDA Infrared Interface (CN12): Supports IrDA 1.0 standard infrared communication and can be used for wireless diagnosis or short-range data exchange.

SMBus interface (CN16): a system management bus used for communication with SMBus devices such as smart batteries and temperature sensors.

MiniPCI Type III slot (CN13): As mentioned earlier, it is used to expand various MiniPCI modules.

3. Front panel control interface (CN21)

The 20 pin pin header integrates complete control signals from the front panel of the chassis, including:

Power LED (PLED): Indicates the system's power on status.

Hard Disk Activity LED: Indicates IDE/ATA bus activity.

RESETBT: Supports hardware reset.

ATX power control (PWRON/PWRBT): Supports soft switch control of ATX power (short press to power on, long press for 4 seconds to force shutdown).

Keylock: Disable keyboard function when short circuited to GND.

PC speaker (WDSPK): Provides audio prompt sound output.

4. Specialized industrial functional interface

External temperature sensor interface (CN11): can be connected to an external thermistor to monitor the internal ambient temperature of the chassis.

Chassis Open Detection Interface (JP5): Connect the limit switch sensor of the chassis to trigger a system alarm when the chassis is opened.

External LAN status LED interface (CN4): can be exported to the front panel to display network connection, activity, and speed status.

Engineering deployment and selection suggestions

Scenario 1: Semiconductor Equipment Control Platform

The control system of a wafer handling robot requires controlling multi axis servo drives, collecting a large amount of digital I/O, and running real-time control algorithms. Select the NuPRO-780DV (dual network port) model, with two network ports connected to the equipment control network and the factory MES system respectively, to achieve physical isolation of data acquisition and control instructions. The onboard ISA has high driving capability and supports stable operation of multiple old ISA motion control cards without the need for additional bus expansion. The hardware monitoring function tracks CPU temperature in real-time to ensure system stability under high load continuous operation.
