5.Reading Sequence and Format. When this program executes, the readings are transferred to the memory card and later displayed in the following sequence:

INSerter digitizer reading 1 INSerter digitizer reading n

.

.

GENerator digitizer reading 1 GENerator digitizer reading n

The memory card stores the readings in the digitizer’s packed data format. Packed readings are signed, 16-bit numbers preceded by the ANSI/IEEE Standard 488.2-1987 Definite Length Arbitrary Block header. Packed readings are always numbers between -1.0230 (-2046) and +1.0235 (2047). To convert the readings to voltages, each reading is divided by 16 to remove the data label bits (0 - 3), and is multipled by 0.0025 which is the reading resolution for the 5V range.

6.Additional Information. Additional information on Local bus operation and on the Local bus commands can be found in Chapter 3 - "Understanding the Digitizer", and in Chapter 4 - "Command Reference." Information on the digitizer’s Arm Source register can be found in Appendix C - "Register Programming."
