Sensoray Model 626 Instruction Manual 5
3. Introduction
The Sensoray model 626 is a Multifunction I/O card.
Some of the features include:
• 48 digital I/O channels.
• 20 of the digital I/O channels have edge detection and interrupt capability.
• 7 of the digital Outputs can be used as counter overflow outputs.
• Digital I/O connectors are industry standard pinouts.
• Watchdog timer with several selectable reset periods that can reset the PCI bus.
• Six 24 bit up/down counters arranged in 3 pairs with:
• Inputs that can be driven in various modes (1x, 2x, 4x) from incremental encoders inputs, the digital inputs, the
paired counter’s overflow, the system clock or software driven.
• Can generate an interrupt on counter overflow or encoder/digital input index.
• Can be preloaded/cleared on an overflow.
• Output of second counter can be captured on the overflow of the first.
• Can be used as a programmable periodic interrupt generator.
• Counter circuitry can be battery backed up to prevent count loss during a power failure.
• Charge control of the backup Ni-Cad battery.
• 16 differential analog inputs (14 bit resolution).
• 4 analog outputs (13 bit resolution) with remote sense inputs to compensate for any external output resistance.
4. Device and Vendor Identification
This is the information that identifies the 626 board in the PCI system.
Device ID: 7146(hex)
Vendor ID: 1131(hex)
5. Installation
The installation of the Model 626 into a PCI system is straight forward as no special adjustment
(jumpers) are required.
