5.3.1.3 Control LED
There are five control LEDs.
5.3.2 Interfaces
5.3.2.1 RS 232
The serial output may be configured in several ways. The transmission rate is adjustable be-
tween 9600 and 19200 Baud, the output protocol may be chosen as either "transparent" or
"3964 R" (see also sections B on page 48 and C on page 49). Apart from that, the content
of the telegrams is configurable, as the user may choose from a list of parameters. Serial
commands are used for activating a system monitor.
5.3.2.1.1 List of System Data that may be Output
A telegram of the serial RS 232 output consists of max. 13 bytes.
The minimum update rate at 9.6 KB is then calculated as follows:
Figure 12
Formula: Minimum update rate
As the transmission is binary, it is possible – when using the 3964R procedure – to add fur-
ther (DLE) characters by this procedure.
All multiple byte variables are output either with the highest byte or the lowest byte first (ad-
justable)! The 8 bit check sum is only output when using the transparent protocol. It then
includes the start character. The start character, as well as the check sum (transparent pro-
tocol) cannot be removed from the data block.

LED Colour Function
PWR yellow shows the current operating voltage
CD yellow lit, when the receiving voltage exceeds <Threshold for Decoding>
DATA yellow Blinks, if transponder approaches (also at noise), is lit constantly
when the transponder is read reliable
POS green represents the positioning output
ERR red is lit when the error bits DEC_HW_ERR, PARAM_ERROR or
ANTENNA_ERR are set or when the reference transponder test
was unsuccessful
(see also Table 7 on page 19)
