4.4 DIP switch settings
Using the DIP switches S1 to S8, various parameters can be set.
Write protection can be enabled using DIP switch S1. In this way the writing of data to the Electronic-Key
read/write is prevented.
The settings are only applied when the power supply is switched on.
DIP switches, 8-pole:

Functions Factory setting
S8 OFF = Electronic-Key read/write ON = Electronic-Key read-only * OFF
S7 OFF
S6 OFF
S5 OFF
S4 ON OFF ON
S3 ON

S2 OFF
S1 ON = write protection for Electronic-Key read/write OFF
* The read-only transponder type can also be read using the Electronic-Key adapter with serial interface. However, we do
not recommend using this transponder type in new installations.
It is imperative that all DIP switches without a function (S2 and S5 to S7) are set to OFF! In this way
problems with any functions added in the future will be avoided.
4.5 OUT output
The OUT output signal changes from inactive (0) to active (1) if there is a functional Electronic-Key in the
Electronic-Key adapter. This signal can be used for control purposes to detect whether there is a Electronic-Key
in the Electronic-Key adapter. The function is identical to the "Electronic-Key active" LED display (yellow).
The OUT output is available on the Electronic-Key adapter with two different levels. On pin 8 of the serial
interface socket with RS232 level (for use as CTS signal on the RS232 interface) and on pin 3 of the power
supply screw terminal with a level of DC + 24 V (inactive = 0 V, active = DC + 24 V) for use as a handshake
signal e.g. with a PLC.
4.6 LED display
The operating statuses of the Electronic-Key adapter are displayed on a 2-color LED on the front.
The illumination of the LED with any color indicates that the operating voltage is present.
Color Operating status Description
