Technet Advanced Data Format

Technet Advanced Data format and X-RITE PhotoTechnet Advanced Data Format

Eastman Kodak specifies an ASCII data format for all RS232-C communications between its software applications and any photographic densitometer. Over the years this protocol has become a defacto standard. It is supported by most makers of photographic hardware and software. All X-Rite photo units support this definition. The Advanced format identifies both the channel and the filter set being used for all measurements. An older Technet protocol is also specified (see Related Support).
Below are listed notes regarding the more recent Advanced Technet protocol:

 

ASCII text data is transmitted in one or more fields of the following structure:

 

L###<cr>

Where:      
  L A lead identifying character (v, r, g, b [Status A Transmission])
    (p, c, m, y [Status M Transmission])
    (P, C, M, Y [Status A Reflection])
  ### The measured density - NO decimal point - assumed between 1st & 2nd
  <cr> The ASCII carriage return character (Chr$ (13))

 

If multiple fields are transmitted, they are passed in the following order: V, R, G, B

 

L###<spc>L###<spc>L###<spc>L###<spc><cr><lf>

Where:      
  L A lead identifying character (v, r, g, b [Status A Transmission])
    (p, c, m, y [Status M Transmission])
    (P, C, M, Y [Status A Reflection])
  ### The measured density - NO decimal point - assumed between 1st & 2nd
  <spc> The ASCII space character
  <cr> The ASCII carriage return character (Chr$ (13))
  <lf> The ASCII line feed character (Chr$ (10))
