Output The analog outputs can be disconnected from the field wiring change may be initiated by register access, however, outputs for offline testing. Calibration and self-test are initiated by a are double buffered which allows all channels to be VMEbus system reset or by execution of a software synchronously updated by either a software or external command. During calibration, a table of offset and gain trigger. coefficients is compiled and stored in RAM. There is an entry for offset and gain corresponding to each of the 32 channels configured in each of the six output voltage ranges. Self-Test: Self-Test is run automatically after system reset. The Self-Test Register indicates success or failure and can indicate the channel which has failed. Front Panel Status LED: The LED is illuminated after a system reset. The LED is extinguished on the successful completion of self-test and autocalibration. The LED can also be turned ON and OFF under software control. 2 VMIVME-4140 32-Channel 12-bit Analog Output Board Address Map: Accuracy, Initial : Maximum error at +25°C: Offset from base address ±0.03 percent setting ±0.025 percent SPAN ±1.5mV Gain Error Offset Error Example: for a setting of +2.000V on the ±5V range: $0000 Registers, Max Error = (±0.03% x 2.000V) ± (0.025% x 10V) ±1.5 Commands and = ±0.6mV ± 2.5mV ± 1.5 Reserved = ±4.6mV $0040 Note: Initial accuracy is established when the board is Output Data channel-calibrated directly after reference calibration.
