PCI-AOB8/12 (16/12) User’s Guide
In addition to 'a' and 'b' as shown above, the EEPROM contains a table of ranges assigned to
each channel. Starting at Base+F0, 16 base addresses contain one byte each, from 0-6,
indicating the voltage output range assigned to that channel. It is important to use the
calibration program at least once if the default range (+/- 10V) is changed on any channel, to
allow this table of data to be reconfigured. If this data is incorrect, calibration is not
guaranteed.
