Program Controlled and External Start Convert Mode

The PROGRAM CONTROLLED START CONVERT MODE is enabled by inserting jumper JD. This mode is detailed in “Program Control Update Mode” on page 4-4 and “Delayed DAC Update Mode” on page 3-6. With no jumper installed at JD, the board operates in the IMMEDIATE DAC UPDATE MODE as described in “Immediate DAC Update Mode” on page 4-3 and “Immediate DAC Update Mode” on page 3-3.

Installing jumper JE enables the EXTERNAL START CONVERT MODE. Jumper JD must also be installed (refer to “External Trigger Update Mode” on page 4-4). The external trigger is buffered in through the P2 connector pin A25 with an associated digital ground wire at pin A26. The locations of jumpers JD and JE are shown in Figure 2-2 on page 2-6.
