Description
HP 12062A Card
The HP 12062A is a plug-in card for the HP 1000 A-Series computers
for low-cost, high-performance analog output capability in small
distributed measurement and control applications.
The HP 12062A Analog Output Card provides 4 independent bipolar
voltage outputs. Remote sensing per channel provides accurate output
voltages compensating for long distances of field wiring. Undedicated
digital outputs may be used in pen up/down control, CRT display, or X-Y
plotters.
DMA-compatibility provides fast analog updates on a per channel basis
or between channels. Programmable time delay between DMA updates
provides signal reconstruction capability with a full power bandwidth of
20 kHz.
HP 12062AC Cable
The HP 12062AC 4-Channel Analog Output Cable provides for easy
connection of your application to the HP 12062A. The HP 12062AC provides
a 3-meter cable prewired to the appropriate card-compatible
edge-connector/hood assembly. Each channel is an individually shielded
twisted pair for optimal analog performance. The "remote" end of the
cable is unterminated allowing direct wiring to the application.
Alternately, the cable may be wired to the easy-to-use insulation
displacement HP 12064A Termination Accessory providing
electrician-compatible heavy-duty screw terminals and built-in wiring
tray (see HP 12064A data sheet).
User Programming
User programming of the HP 12062A card is easily accomplished using the
parallel interface I/O driver (ID.50) in the RTE-A Operating System. A
simple RTE EXEC call in the following format is used:
Call EXEC (2, LU#, Data Buffer, #readings, control word) D
The control word specifies a time delay between successive DMA word
transfers. Each increment (up to 255) in the control word adds a 1.085
microsecond time delay to the 10.85 microsecond base rate.
Calibration
The HP 12062A is calibrated at the factory and may require recalibration
by the customer upon arrival by using a voltmeter and optional
calibration software.
