System dependent Double buffered output latches Update DACs individually or simultaneously (jumper selectable by pairs)
 Power up and reset option, jumper selectable (revision 3 and up): With
jumper set to "ZERO", all DAC's cleared to 0 volts, ±32 mV, DACs set tosimultaneous update mode until first read. With jumper set to "STD", DAC
output on power-up is undefined.
