Double Sequences
If the system has to operate with double sequences, digit 1 of register 021 (EEPROM 1) has to
be programmed with a '1'. Now after every evaluation of decoder 1, a time window of 1 second
is opened. The rst ID-code, within the time window, which ts the key tones, closes the time
window. The rst or the second ID-code can be transferred to the ID-code memory (according to the
"ID-Mode" switch). Therefore, the acknowledgement transmission is delayed.
Key Tones
The key tones are coded in register 008 (EEPROM 1). The coding of these tones selects the
ID-codes which are stored, and determines the digits to be displayed. Those digits where every tone
is allowed and which are displayed later on, have to be coded with 'F'.
Memory Updating
Before an ID-code is accepted by the ID-code memory, the software checks if the same ID-code
has already been stored in the memory. If the ID-code has already been stored and if the updating
has not been activated, the ID-code is rejected. If the updating is switched on, the ID-code at
the old position is deleted in order to be stored again at the rst position. Therefore, the ID-code
memory is always arranged in chronological order. The memory updating is programmed at digit 5
of register 021 in EEPROM 1 ('0' = off, '1' = on).
Display
The ID-code can be shown on the left as well as on the right display. In case of up to 3-digit
ID-codes the left display should be chosen. The ID-code is always displayed right aligned. If the
ID-code display is requested on the left display, digit 4 of register 021 (EEPROM 1) has to be
programmed with a '1'. If the ID-code shall be shown on the right display, please code a '0'. If an
ID-code is shown on the right display, it can be transmitted via the call button. If the ID-codes
shall be shown on the display automatically after storage, digit 2 of register 021 (EEPROM 1)
has to be programmed with a '1'.
Example:
The following example shows the conguration of an ID-code memory which stores and displays
automatically every ID-code beginning with 1 2. The ID-code memory should be "updated":
Register 008 1. digit
1
2. digit
2
3. digit
F
4. digit

5. digit

Register 021 1. digit
