Raw Data Readback by "paging" bpm raw data readback N:IBPMIN - index for selecting bpm to read (1-21) N:IBPMPG - page to report from each channel (1-16) to support up to 128k samples N:IBPMRA[0:N] - Raw ADC samples for channel A for selected bpm N:IBPMRB[0:N] - Raw ADC samples for channel B for selected bpm N:IBPMRC[0:N] - Raw ADC samples for channel C for selected bpm N:IBPMRD[0:N] - Raw ADC samples for channel D for selected bpm
The existing SSDNs Channel IDs stop at 216 (0x00d8), so we will use 220 (0xdc)
This will be six (6) new SSDNs (0?dc/0000/0000/0000):
- Chan 0 - The reading/setting of the BPM to return (00dc/0000/0000/0000)
- Chan 1 - the reading/setting of the page number of the raw data to return (01dc/0000/0000/0000)
- Plate P - The plate reading. (0Pdc/0000/0000/0000) - P=2, 3, 4, or 5 for A, B, C, or D, respectively
Note that the last three words of the SSDN are ignored.
Thus, setting the device with the (00dc) SSDN to 1 and the (01dc) SSDN to 5 will cause readings on each of the four other SSDNs to point to the raw array values of the second BPM at the 6th page of the full data array.
