Description:  Command to retrieve the current value of all active ADC values.  The data is placed into 
the scratch pad buffer.  

Command Code: Enumeration for CMD_GET_ADC_VALUES 

Argument Size: 0 

Argument: Null 

Note: Use the McbReadDataMem function to read data from scratch pad.  This command was added 
for developmental purposes.  The ADC channels read:  ADC A Channels – 0 through 7, ADC B 
Channels 0 – 3, 7. 

Description:  Enables or disables the selected reticle on the overlay symbology.  

Command Code: Enumeration for CMD_ENABLE_RETICLE 

Argument Size: size of RETICLE_XFER 

Argument: See below. 

struct _RETICLE_XFER { 
 

unsigned 

select:1; 

 

// Select A (0) or B (1) 

 unsigned 

enable:1; 

 // 

Reticle 

Enable 

 

unsigned 

horPos:9; 

 

// Reticle Horizontal Position 

 unsigned 

size:4; 

 //

unsigned empty:1;  

// 

Open 

 

 

 

unsigned 

emissivity:8; 

// Reticle Emissivity 

 

unsigned 

verPos:8; 

 

// Reticle Vertical Position 

}; 
typedef struct _RETICLE_XFER RETICLE_XFER, *PTR_RETICLE_XFER; 
 

Note: The data contains all the data needed to enable the reticle on the desired screen location. 

Description:  Move the selected reticle to desired location.  

Command Code: Enumeration for CMD_RETICLE_POSITION 

Argument Size: size of RETICLE_XFER 

Argument: See paragraph

. 

Note: This command and CMD_ENABLE_RETICLE are functionally identical. 

Description:  Perform a directed 1-point update calibration.  Offset coefficients computed by the 
calibration are stored in NUC flash (become part of the permanent NUC coefficient set).  

Command Code: Enumeration for CMD_ONE_PT_UPDATE 

Argument Size: UWord16 

Argument: 0 – do not use internal calibration flag, 1 – use internal calibration flag. 

Note: Since the 1 point update calibration may require placement of reference source, it is necessary 
to implement this command in ‘sub-protocol’ form.  See paragraph

 for details. 

Description:  Command to write value to video encoder register.
