Reticle Parameters:
If Rtcl X En = 1, then Draw Reticle X at the Reticle X Horizontal / Vertical Position.
If Reticle Emissivity is 0, Report Intensity on Overlay.
If Reticle Emissivity is not 0 Report Temperature on Overlay.
Reticle Radiometric Control:
Temp Unit 0 – Display Temperatures in Fahrenheit;
1 – Display Temperatures in Celsius
AGC Mode:
Agc Mod 0 – AGC/ALC Off (Hold Present State);
1 – Manual Contrast Adjust;
2 – Linear AGC/ALC;
3 – Histogram AGC/ALC;
4 to 15 – Reserved
Active ROI Index:
Selects the Currently Active ROI Index (0 <= Act ROI Index <= 7).
Use the Appropriate Op Mode Descriptor Table Values to Load the FPA Processor Registers.
Display Video Manual Low / High Intensity Parameters:
If Agc Mod = 1, then:
Intensity Transform = (Input – Manual Low Intensity) * (255/(Manual High Intensity – Manual
Low Intensity)).
AGC Limit Intensity Parameters:
See below.
