5.4 CORE Commands for 5I External Interface [EDSU]
Cooke 5I lenses allow users to append additional external data (up to 60 8-bit values) onto
the data stream normally generated inside the lens. External data is retrieved through the 5I’s
external communication interface and then appended to the D, C, Kd or Kc response stream.
The appended string must consist of 8 bit characters which do not include the [l/f] or [c/r]
character, and preferable no other ASCII control character ( hex 00 to hex 1F).
