1 Introduction

The individual command set of a readers or decoders manufactured by AEG ID base on standardized com­mand sets, that are specific to each class of readers/decoders. This standardized command sets are desig­nated as ASB, which means AEG ID Standardized Command Set. The standardized command sets make it
possible to use different hardware components (within a class of readers/decoders) without modification of
the software application.

The command set of the ARE K1 is compatible to the ASB 1.0. Beyond it the ARE K1 RS232 is provided
with a special command for self-diagnosis and extended parameter settings as well.

The difference between the command set of the ARE K1 and the ASB 1.0 is made quite clear at the rele­vant subjects in this description.

2 Modes of operating

Three basic modes of operating are defined:

• Operating mode 0 (continous mode) - reader is automatically triggered

• Operating mode 1(external mode) - reader is externally triggered

• Operating type 2 (command mode)- reader is triggered by serial interface

2.1 Change of Operating mode

The operation mode of the ARE K1 can be changed out of each operation mode using the MD command1.

this behaviour is not universally applicable at ASB 1.0

2.2 Operating mode 0 - continuous mode

When operating continuously the exciter is switched on permanently. The reading cycles are initiated peri­odically.

After an accomplished reading cycle the reading information is evaluated. After that data (either trans­ponder number or NoRead code) is output to the serial interface.

2.3 Operating mode 1 - running externally triggered

In operation mode 1 the exciter is turned off. As soon as the external triggered signal rises from logic 0
to 1, the exciter is started and a reading process is initiated.

ID

After a successful reading cycle, the exciter is turned off immediately (irrespective of the trigger signal).
The next reading cycle starts at the next leading edge (0 to 1) of the trigger signal.

If a reading cycle is not successful, the reading process is controlled by the state of the external trigger
signal: further reading cycles are started as long as either a successful cycle has occurred or the exter­nal trigger signal is logic 0 again. In the latter case the identification NoRead code is output.

2.4 Operating mode 2 - reading triggered by the serial interface

In operating mode 2, the exciter is always turned off. Triggered by the command GT, the exciter is acti­vated. After successful reading of a transponder number the exciter is turned off automatically.

If the first reading cycle yields no result (NoRead), the on-time of the exciter is limited by the parame­ter TOR (time out reader): Reading cycles are continuously started until either a transponder is read
successfully or the time span corresponding to the value of the parameter TOR has expired. The reader
will not interrupt the last running readout cycle. If no transponder number has been read, a NoRead is
output.

Please note: Within the time span defined by the value of TOR no NoRead will be output on the interface!

3 Protocol format

The command set described in this chapter defines the transfer of data on the serial interface.

The commands consist of a command code and of a parameter value optionally. Commands are termi­nated by the control character <CR> (13H). The control character terminates the command line.

Command codes and parameters, that means all letters and numerical values, are principally transmitted as
a sequence of ASCII characters (the value 255 (decimal) consequently as 32H, 35H, 35H; the command
RST as 52H, 53H, 54H).

3.1 Echo function

The echo function can be switched on or off.
