5. CORE Command Set
5.1 CORE Commands for All Lens Types
Commands to a lens are in ASCII format and terminate with a carriage return
character. Responses from a lens are in either ASCII format or packed binary format and
terminate with the character pair, linefeed carriage-return: [l/f][c/r].
5.1.1 N Command:
Retrieve Fixed Data in ASCII Format: Typical Response (see exceptions by Lens type)
The first command a lens receives must be the N command. When sending data in response
to a command, a lens typically echoes back the command as the first character in the response
string.
Note: Some older lenses and S4 I lenses have N command responses that vary slightly.
Please see Appendix A.1 for details. All 5 I , Panchro I and Zoom lenses provide the following N
command response and will remain consistent for all lenses in the next development cycle.
