2.2.2
LEDs
4 LEDs are provided for function control:
2.2.3
Turn on Characteristics
On activation of power supply the positioning output will be active (approximately 500
ms) for the duration of the reset. All LEDs will be connected additionally for 500 ms.
After approximately 2 s the device is ready for operation.
2.2.4
General Information
The code supplied by the transponder has a sequence of 24 bits, 16 bits are coded.
They are output serially or parallel with an optional serial / parallel interface .
2.2.5
RS 232 Interface
For communication of the computed data to the outside world the interpreter transmits
the code of a transponder in the interception range. The output is realized correspon-
dent to the chosen adjustment via RS 232 interface (see Table 3 on page 11).
If there is no transponder in the field no protocol will be transmitted.
2.2.5.1
Interface Parameters
The parameters of the serial data transmission depend on the adjustment of the DIP
switches on the evaluation board (see Figure 7).
