- Calculated Pulse Width
- Edge Detection Threshold
- Disabling/enabling timing check
- Setting the timing check margin
- Setting the Edge Detectoin threshold
- Setting the pulse direction
- Displaying the status of the timing check for each device
- Displaying the timing check margin of error
- Displaying the edge detection threshold
- Displaying the pulse direction for each device
Create ACNET devices for the Ring Pickup's calculated pulse width and edge detection threshold.
Enable the timing check for the Ring Pickup in the startup script.
Set the timing check margin to 0x80.
Initialize the edge detection threshold to 0x1000.
Set the pulse direction to 0.

Moved cout's related to MPS status into Toroid::show().
Added lines to the MPS status display for all of the bullet points listed above.
Began implementing the necessary methods for accessing the new MPS features to IIntMonitorDev, Toroid, DAQPool, IIntDAQ and MirrTorDrv.

- % Done changed from 0 to 30
Implemented output for the new MPS features in Toroid::show().
Toroid Device ID: 0 ADC ID: 0, channel: 0 Readouts: BBB disabled, raw disabled DAQ Source: 0 MPS: Enabled, Lower: 0, Upper: 0, Edge Threshold: 0, Pulse Direction: 1 (+), Time Check: Disabled NOT TRIPPED

Implemented the following CLI commands:
vmeintMPSTimingCheckEnable device_id
Enables the check of calculated pulse length to the set gate width for device_id. If they are exceeded by the timing check margin then the board trips the MPS alarm.
vmeintMPSTimingCheckDisable device_id
Disables the timing check for device_id.
vmeintMPSTimingCheckMarginSet device_id, margin
Sets a margin of error for the timing check comparison for device_id. The margin parameter is given in ADC clock cycles.
vmeintMPSThresholdEdgeSet device_id, threshold
Sets a threshold to use when searching for the beam pulse for device_id. The threshold parameter should be a signed-16 bite integer representing raw ADC counts.
vmeintMPSPulseDirectionSet device_id, direction
Sets the expected beam pulse direction for device_id. The direction parameter should be 0 for a negative pulse and 1 for positive.

ACNET device support:
Register | Device ID | ACNET Device Property | VMEInt method | SSDN Channel is |
---|---|---|---|---|
Edge Detection Threshold (0x2D8) | 0x63 | Reading of Setting | VMEInt::mpsThresholdEdgeGet | Intensity Device ID |
.. | .. | Setting | VMEInt::mpsThresholdSet | .. |
Calculated Pulse Width (0x2e8..0x304, for channels 1 through 8) | 0x64 | Reading | VMEInt::mpsPulseWidthGet | Intensity Device ID |
For nbeam:
Device ID | ACNET Device Name | Intensity Device ID | SSDN |
---|---|---|---|
0x63 | Z:990MPE | 0x00 | 0063/0020/0000/0000 |
0x64 | Z:990MPW | 0x00 | 0064/0020/0000/0000 |
For PXIE Ring Pickup:
Device ID | ACNET Device Name | Intensity Device ID | SSDN |
---|---|---|---|
0x63 | P:MPRET | 0x03 | 0063/0020/0000/0003 |
0x64 | P:MPRPW | 0x03 | 0064/0020/0000/0003 |

- File 125MHz_Digitizer_Firmware_Description_ABB12.pdf 125MHz_Digitizer_Firmware_Description_ABB12.pdf added
New documentation from N. Liu: "PXIE Toroid and Ring Pickups Changes in firmware version ABB12 / 125MHz Digitizer Firmware Description". This document is not internally dated, but I received it on October 24, 2016.

Notes for manipulating the VME registers (from N. Liu)¶
0xf0f012d0 -- Trips channel 0xf0f012c8 -- First MPS width channel has tripped (can be cleared to 0x00) 0xf0f013c2 -- set to 0xff to reset the trips

Hardware version number has incremented to abb12.
Have implemented and tested devices Z:990MPW and Z:990MPE.
