Parameters
5.8.5.3 General Match code teach-in - settings
The General Match code teach-in - settings group contains the parameters for teaching in
matchcodes.
The two matchcodes are stored in the Matchcode Teach-in 1 and Match-code Teach-in 2
(Additional) group respectively and can be subsequently modified individually.
5.8.5.3.1 Start teach-in
The Start teach-in parameter is used to select the signal that triggers automatic teach-in of
a matchcode.
• A
UTOMATIC/STATIC: The reading gate is automatically opened by a signal (e.g. a key switch).
The next read code is taught in as a matchcode.
• M
ACHINE TRIGGER / DYNAMIC: Matchcode teach-in is prepared by a signal (e.g. a key switch)
at one of the digital inputs of the LECTOR
®
620. After the reading gate has been opened
(usually by a light barrier), the next read code is taught in as a matchcode.
5.8.5.3.2 Allowed code types
You use the Allowed code types parameter to define which code types are to be taught in
as the matchcode.
As every code of a different code type could also be interpreted as a pharmacode, the Phar-
macode code type must be selected exclusively.
• A
CTIVATED CODE TYPES: In accordance with the code configuration, all activated code types
are accepted for matchcode teach-in. To ensure that the desired code type can be read, the
code configuration must first be checked.
• A
LL TYPES (EXCEPT PHARMACODE): All code types except Pharmacode are accepted for match-
code teach-in.
• O
NLY PHARMACODE: Only codes of code type Pharmacode are accepted for matchcode
teach-in.
5.8.5.3.3 Code configuration
You use the Code configuration parameter to define whether and how the teaching in of a
matchcode should affect the current code configuration.
• D
ON'T CHANGE: The current code configuration is not changed by a matchcode teach-in. All
configured code types can continue to be read.
• L
IMIT TO LAST TAUGHT CODE: The code configuration is adapted to the taught-in matchcode.
The parameters for code type, code length, and code content are limited to the properties
of the matchcode. As a result, only codes that match the matchcode can be read.
• E
XPAND BY LAST TAUGHT CODE: The code configuration is adapted to the taught-in matchcode
by also activating the parameters for the taught matchcode. As all other code settings re-
main unchanged, all configured code types can continue to be read.
