8.9.1.5 Euchner card reader
An ID device of type Euchner, that is, a Euchner Electronic-Key-System reader of type EKS-A-ASX, is
equipped with a 24V output signal (data carrier active) that is used by PowerMACS to know when the
reader has a card. When a card is inserted in the reader, the 24V signal goes high. This triggers
PowerMACS to start communicating with the card reader and fetch the data from the card. Whenever the
signal is set low PowerMACS clears the read data.
Use DI for Euchner card reader to specify which PowerMACS I/O input that the "data carrier active"
signal is connected to.
Note! The Euchner device must be configured to use Baud Rate 9600, Parity = Odd and Data Bits = 8.
