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:

DIP

switch

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

RS232

RS422

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

Green Ready Electronic-Key adapter supplied with power and ready.

Yellow Electronic-Key active There is an Electronic-Key in the Electronic-Key adapter and it has been detected.
