Description

THIS PRODUCT HAS BEEN DISCONTINUED

FUNCTIONAL DESCRIPTION

Model PAD128 is a type II PCMCIA card (PC card). It performs data acquisition on up to eight analog inputs and provides parallel digital input/output capability for up to 16 bits. A 24-inch long cable that mates with the PAD128 on one end and has a 37-pin male sub-D connector on the other end is available as Model PAD128CAB.

DATA ACQUISITION

The analog-input configuration is software controlled on a channel-by-channel basis and you can have any combination of single-ended and differential inputs that adds up to eight pins. The PAD128 has the following input range capabilities:

Channel 0 and 1: +/-10V
Channel 2 and 3: +/-5V
Channel 4 and 5: 0-5V
Channel 6 and 7: 0-100mV

Settle time for the input Multiplexer and Sample and Hold amplifier “front end” is programmable to permit use with signals that have source impedances higher than 80 ohms. The analog-to-digital converter provides 12-bit resolution on a 5-volt input voltage range. Overall throughput rate is a maximum of 140,000 samples/second. Conversions can be initiated either by an external “sync” input to the card or by a programmable on-card pacer clock. The A/D converter has self-calibration capability (to eliminate linearity and zero-drift errors) and a 32-sample FIFO buffer. The buffer allows accumulation of data while the computer is servicing other requests.

DIGITAL INPUT/OUTPUT

The PAD128 also has capability for 16 digital input/output bits that can be programmed as inputs or outputs on a groups-of-eight basis. This function is based on the industry-standard type 8255 programmable peripheral interface and the A and B ports are available for use.

SPECIAL FUNCTIONS

Control logic in the PAD128 uses a programmable array and special functions can be factory programmed. If you have need for special functions such as limit comparison, interrupt logic, etc., give us a call.
