How apply the Inotec coding scheme
The Inotec coding scheme provides the maximum number of
combinations for safe protection D-Sub interconnections
against mismating.inotec-electronics.
For this reason, simultaneous
use the coding schemes “1”
and “70” should avoided.
Single-sided coding
Under unfavorable conditions, coding with
pins only one connector side might lead unintended
contacting (connector may tilt like shown picture below)
despite correct coding. using least pins each cable and
mating side, unintended contact mismated connectors can
be securely avoided.124 www.com
Processing information
Unambiguous documentation
The chosen coding scheme and the combination should be
unambiguously recorded, that correct coding can be
carried out safely even when the connectors mating side
and cable side are assembled different sites.g.
Then specific combination for specific interface
(e. “ABCD
always female and abcd always male connector”).
Here’s how the selection coding scheme done:
first step basic rule has set (e.
Inotec coding system for D-Sub interfaces
. “scheme for signal 1”) has chosen
Finally insert the coding pins into the corresponding
coding elements according the processing information
mentioned below. the following illustration you can see all
70 possible pin combinations for safe and reliable coding of
your D-Sub interconnection
