====== Command:PR ======

This is a Tiger only command, that has different usage for MicroMirrors and Piezos.

--> MicroMirror ^

^Shortcut  |PR| 
^Format  |PR [axis]=[5 to 10] …|
^Units    |Integer code|
^Type    |Axis-Specific  |
^Remembered |Automatically |
^Firmware Required|v2.83+|

This command is “recycled” for a different use in MicroMirror axes than for piezo. In the context of a MicroMirror axis this command is used to set the MicroMirror travel range. Settings is automatically saved into non-voltatile memory, however controller needs a system ''RESET'' or ''RESTART'' for setting to take effect.

^PR[Axis Name] =	^MicroMirror Range \\ <wrap lo>in degrees</wrap> ^
|5	|5|
|6	|6|
|8 \\ <wrap lo>(default)</wrap>|8|
|10	|10|

Example
<asi> $ PR A=5		
:A</asi>
Sets range of A axis as 5 degrees
<asi> $ PR A? B?			
A=5 B=8 :A</asi>
Queries the range of axes

--> Piezo ^ 

^Shortcut  |PR| 
^Format  |PR [axis]=[0 to 8] …|
^Units    |Integer code|
^Type    |Axis-Specific  |
^Remembered |Automatically |

PR is used to set the piezo travel range. It is an Axis specific command. Setting is automatically saved in the non-volatile memory. Will need a system RESET or RESTART for setting to take effect.

^PR [Axis Name] =	^Piezo Range \\ <wrap lo>in microns</wrap> ^
|1	|50   |
|2	|100  |
|3	|150  |
|4	|200  |
|5	|300  |
|6	|350  |
|7	|500  |
|8	|70   |

--> Tunable Lens ^ 

^Shortcut  |PR| 
^Format  |PR [axis]=[0 to 3] …|
^Units    |Integer code|
^Type    |Axis-Specific  |
^Remembered |Automatically |

PR is used to set the Tunable Lens units or user input. It is an Axis specific command. Setting is automatically saved in the non-volatile memory. Will need a system RESET or RESTART for setting to take effect. For more info refer to [[:tiger_tunable_lens_card#unitsresolution|Units/Resolution]] section on TGTLC card page.

^ PR [Axis Name] =             ^ Units                                                                            ^
| 1 <wrap lo>(default)</wrap>  | [0 to 290mA] with coordinates -32768 to +32768                                   |
| 2                            | [0 to 290mA] 1/1000 of dpt, <wrap lo>range usually between 26000 to 7000</wrap>  |
| 3                            | [-290mA to +290mA] with coordinates -32768 to +32768                             |

--> SIGNAL_DAC for TGDAC4 / TGGALVO ^

^Shortcut  |PR| 
^Format  |PR [axis]=[0-7] …|
^Units    |Integer code|
^Type    |Axis-Specific  |
^Remembered |restart required (no SS Z required) |
^Firmware Required|v3.3+|

For TGDAC4 card with ''SIGNAL_DAC'' firmware, the bits 0-2 of the specified code sets the output range (values 0-7 in decimal).  Bits 3-7 are reserved for future use. **Controller reset or restart is needed for setting to take effect.**

For the ''SIGNAL_DAC'' firmware, the axis units are always in millivolts (0.001V), regardless of the PR setting. For example, when PR H=2, the maximum axis value of H is 10240. When PR H=0, then the maximum axis value of H is 2048.

^ Code (Decimal)  ^ Code (Binary)  ^ Output range       ^
| 0               | 000            | 0V to 2.048V       |
| 1               | 001            | 0V to 4.096V       |
| 2               | 010            | 0V to 10.24V       |
| 3               | 011            | not supported      |
| 4               | 100            | -1.024V to 1.024V  |
| 5               | 101            | -2.048V to 2.048V  |
| 6               | 110            | -5.12V to 5.12V    |
| 7               | 111            | -10.24V to 10.24V  |



**Example**

<asi> $ PR A=2 B=7
:A</asi>
Puts the output A in 0-10V mode and output B in +/- 10V mode.
<asi> $ PR A? B?			
:A A=2 B=7 </asi>
Queries the mode of axes
