Service Manual 1001 5015 / Rev. 4 4:37
4.12.2 Commands
Presents which command that was sent out before the error occurred.
Position in instrument Hardware Error Code in bold:
E.g. "20 - 304 /1ef3/201/20/0/0/0/450".
DSP Module Commands
Id (hex) Name Note
0001 GetDSPStatus
Read HW status and error words. Updates the
TWM, STM, EID and ASTM installed bit.
0002 GetScanVector Collect vector.
0003 GetSampleVector
Collect specified number of ADC values with
sample interval as specified in the command.
Sample interval 1 means the highest rate (10
s interval).
0004 SetGratingMotor Set grating motor on/off
0005 SetGratingMotorConf Set speed of grating motor
0006 GetGratingMotorConf Get speed of grating motor
0007
GetMonochromatorEnco
der
Read encoder signals
0008
GetFlybackScan (IP mode
only)
If not in 'Flyback' mode: Collects a scan with
the present gain, enters 'Flyback' mode and
waits at the end of the grating cycle.
If in 'Flyback' mode: Calculates new gain on
the way back and sets and collects a scan at
this gain.
000A
LeaveFlybackMode (IP
mode only)
Forces the DSP to leave the 'Flyback' mode.
0010 GetGratingInfo
Returns length of grating cycle, both the
numbers of pulses and time. Also returns a
time vector containing the time intervals
between increments.
0011 GetGratingPwm
Returns length of grating cycle, both the
numbers of pulses and time. Also returns a
time vector containing the time intervals and
PWM levels between increments. The time/
PWM values are returned as follows:
speed,pwm,speed,pwm
0012 GetHopperTemp Get the hopper temp sensor value.
0013 GetADCNoMissingCodes Get ADC no missing codes test result.
001A GetEncoderInfo
Runs motor at fixed PWM and gets
information about pulses for encoderA,
encoderB and index.
001B SetGratingScanRange
Sets scan range for the grating in idle mode
to Normal
Exercise: -1000 to 2000.
001C SetGratingAnalyseMode
Sets scan range to normal mode and sets
grating motor on
0020 SetIPMode Set the mode.
0030 IoPortSetByte Set bits in external port
0031 IoPortGetByte Get bits from external port
