20
In the following table you will find a list of the binary codes used to describe the system
status (for byte # 20 and 21 in Table 2):
*)
These bits are deleted as soon as the Transponder leaves the
Antenna reception range.
Example:
System status
0x0018
Description NO_SLAVE_COM and EEPROM_ERROR.
This status message
0x0002
may also occur during an ordinary transponder cross-
ing, if the code transmission is aborted due to decreasing output level.
The connection between „number of readings“ and „system status“ is as follows:
Value
Name
Description
0x0001
DEC_HW_ERROR
code decoder hardware error
0x0002
CODE_PAR_ERR
reception of transponder code with parity error or Hi-Nibble
received
0x0004
RX_NOISE
Set whenever TRANS_IN_FIELD was set but no codes
were received
0x0008
NO_SLAVE_COM
No communication with slave processor
0x0010
EEPROM_ERROR
parameter E²Prom not addressable
0x0020
PARAM_CRC_ER
parameter block not safe
0x0040
POT_ERROR
IIC-Bus Potis not addressable
0x0080
F_ERROR
Transmitting or receiving oscillator not tuned to the set fre-
quency
0x0100
ESTIMATE
If the exact Transponder Position cannot be determined
due to wrong reading distances or e. g. steel reinforce-
ments in the ground, an estimated value with the accuracy
of ±46 mm is determined and this bit is set
0x0200
TRANS_IN_FIELD
transponder is being detected *)
0x0400
CODE_OK
Code decoded without errors *)
0x0800
0x1000
POSIPULS
Transponder has crossed the Antenna center
0x2000
0x4000
0x8000
HEATER_ON
Internal heating active
