Omega 1002 - Manual (Page 5)

1. Introduction
The OME-PCI-1002H/L card provides 12-bit ADC and two 16-bit digital I/O ports.
1.1 General Description
The OME-PCI-1002L and OME-PCI-1002H are high performance multifunction
cards, with A/D and digital I/O for PC and compatible computers in a 5V PCI slot. This
family has the following features: one 12-bit 110K A/D converter, 16 channels D/I, 16
channels D/O, programmable interrupt source and true “Plug and Play” support. The
OME-PCI-1002H/L provides 32 single-ended analog inputs or 16 differential analog
inputs, which are jumper selectable. The OME-PCI-1002L is the low-gain model
equipped with a high speed PGA (programmable gain amp.) with programmable gain
control of 1,2,4,8. The OME-PCI-1002H is the high-gain model equipped with a high-
gain/high-resolution PGA with programmable gain control of 1,10,100,1000. There are 16
channels of TTL compatible digital output and 16 channels of TTL compatible digital
input. This series provides three programmable trigger methods: software trigger, pacer
trigger and external trigger. The external trigger can be configured as a post-trigger, pre-
trigger or external pacer trigger. There are also several selectable interrupt sources: A/D
conversion interrupt, pacer interrupt and external interrupt. This multifunction card also
provides an A/D buffer and a data transfer rate of 2.7M words per second in non-burst
mode. This powerful A/D control mechanism offers flexibility for various applications
while minimizing system I/O overhead. The OME-PCI-1002 series is fully “Plug and
Play” compatible and can operate at the full speed of the PCI bus (33MHz). This
important feature makes the OME-PCI-1002 a high performance, cost effective solution
for most data acquisition applications.
