D.2 A/D Converter Card Channel Layout
The A/D Converter Card contains a single 11-input 12-bit A/D converter, TLC2543. The
method of interfacing to this chip is a combination of single-bit writes via board registers
and synchronous clocked serial access via the CPU Card’s Serial Port B, which is
extended across all eight slots. In addition, a serial EEPROM is installed on the A/D Con-
verter Card to store the calibration constants.
