The least significant bit of every digit is sent first; the fifth bit is an odd parity bit for each group of 4 data
bits.
The complete message always looks as follows:
left edge - start - data characters - end - LRC - right edge
The LRC is calculated by the following procedure:
Each of the 4 bits in the LRC character is an even parity bit of the equivalent bits in the telegram including
start and stop sentinel; i. e. the first LRC bit is an even parity bit for all the least significant bits in the tele-
gram and the 4th bit of the LRC is the even parity of all the most significant bits.
The fifth bit is the odd parity of the 4 LRC bits (it is not calculated over all the parity bits).
On magstripe cards the space left and right of the information (edge) is filled with an unknown number of
zero bits (this is not a valid character as the parity is invalid). As most terminals need some of the zero bits
(known as ‘‘clocking bits’’ too) and do not care about additional zero bits, deister decided to send 16 zero bits
at the left edge as well as to the right edge.

Wiring and Installation Instructions PRM 5
The parity bits, the start and end characters, the LRC and the zero bits at the edge are generated automati-
cally by the reader.
On the one hand, they do not require space in the transponders (therefore we can encode 16 digits for the
user), on the other hand this means that there will be a problem if one of the fields is missing.
Example:
The short information ‘‘86’’ would be transmitted as follows:
0000000000000000-11010-00010-01101-11111-01011-0000000000000000
edge start “8” “6” stop LRC edge
A ‘‘1’’-bit is transmitted as a logic low level; the falling as well as the rising edge of the clock pulse may be
used to clock in data.
4.4 Protocol for PRM 5 with RS 232/RS 485 Interface
(no Partyline protocol)
The interface is operated using 9600 baud, 8 data bits, 2 stop bits and no parity bit.

Calculation of the parity:
LRC = 80h OR [52h Å 45h Å 30h Å 43h Å 35h Å 35h Å 37h Å 30h] = E3h
(‘‘Å’’ means Exlusive-OR)

7 Appendix
7.1 Supervised F2F
It is possible to switch between native and compatible mode using special programming cards.
Note:
For all interfaces except RS 232/485 the pull-ups must be connected to the clock and
data lines.
