The encoder is congured according to the application requirements and as well for comfortable
operation. Logically, you will permanently code those digits which should not be entered via the
keypad. The permanently coded tones can be placed at any position of the manufacturer reference
and call code. For example, it is possible to permanently code positions 4, 6, and 8. In this case only
positions 5 and 7 are entered via the keypad. Usually, the rst two digits (manufacturer reference) or
the rst three digits (manufacturer reference and rst call number digit) are permanently coded. The
positions to be freely entered are always displayed right aligned. The FFSK encoder is programmed
in register 001 (EEPROM 1). See section EEPROM 1 Programming Mode. If not all digits are
permitted, the input can also be restricted (see section Call Code Filter).
Operating Mode Reference
The operating mode reference ("Betriebsartenkennzeichen" = BAK) is the criterion for different
telegram forms:
0

1
Q
Call to mobile
2
Q
Call to master station
3
Identication
4
Acknowledgement
5
Following telegram
6
Q
Break call
7

8

Priority call
9

Emergency call
BAKs marked with Q require an acknowledgement. For call transmission the BAK is coded at the
third digit of register 032 in EEPROM 1 (usually '1' --> call to mobile).
The BAK for call evaluation is programmed at digit 4 of register 032 in EEPROM 1 (usually '2' --> call
to master Station). In case of coding a '0', every telegram is processed by the FFSK decoder.
Limit Number
The limit number is programmed at digits 3 to 5 of register 031 (EEPROM 1). Call codes lower than
the limit number are transmitted as 5-tone sequence; call codes higher or the same as the limit
number are transmitted as FFSK telegram.
Rhomb
The rhomb is programmed at the rst digit of register 031 (EEPROM 1). Application at disposal.
