Analog Output Card and Cable, Technical Data For HP 1000 A-Series Products with 24 kHz Power Product Number 12062A and 12062AC Features o 4 channels of voltage output/card o Output range of 10.24 volts o 12 bit resolution including sign o Short circuit and overvoltage protection o One undedicated digital output per channel o 90 kHz output from memory o Programmable data rates 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.
