The fields highlighted in grey must be filled in (ensure that the digits entered are within the limits indicated):
1. Calculation of the memory requirements for the cards
Header:
ID no.:
PIN-code:
Version no.:
R/T-zones:
This is a preset value using 13 bytes for each card.
Enter the number of digits of the identification code to be used in the column 'no.

of digits required' (e.g. 20 in case of 20-digit coding according to Esser or DIN).
Divide this number by 2 and enter the result in the column 'value'. (This indicates

the required number of bytes to hold two decimal (0-9) digits each).
ID no.: if the result of the division is not an integer (e.g. 7.5), the result must be

rounded up to the next integer (for a 'value' of 7.5, this would be 8) and entered in
the column 'rounded to the next integer'.
Enter the number of digits of the PIN code to be used in the column no. of digits

required (the PIN code must be from 4 to 8 digits long).
Divide this number by 2 and enter the result in the column 'value'. (This indicates

the required number of bytes to hold two decimal (0-9) digits each).
If the result of the division is not an integer (e.g. 2.5), the result must be rounded

up to the next integer (for a 'value' of 2.5, this would be 3) and entered in the
column 'rounded to the next integer'.
Enter the number of digits of the version number to be used in the column no. of

digits required. Contactless / proximity cards use a unique number twenty digits
long. In this case, no version number is required. In all other cases, a two digit
version number is entered. It is recommended to enter 2. ?
Divide this number by 2 and enter the result in the column 'value'. (This indicates

the required number of bytes to hold two decimal ()0-9 digits each)
If the result of the division is not an integer (e.g. 0.5), the result must be rounded

up to the next integer (for this example, to 1) and entered in the column 'rounded
to the next integer'.
Enter the number of required room/time zones. Divide this value by 8 and round the

result to the next integer. the ACS-8 stores only those room/time zones, to which
doors are allocated controlled by this controller.
