Example for calculating the check sum CRC
Example 1 (BCD-coded text call-up) on page 3-26 shows how the check sum CRC is
calculated.

First of all, calculate the sum total (

) of all bytes from byte 2 (slave address / ID-Byte) up

to and including the last data byte (Data (DL); Byte 7 in the example).

To calculate the check sum CRC, follow the procedure depicted below, using the sum
total (

In Example 1:

Byte 2

Byte 3

Byte 4

Byte 5

Byte 6

Byte 7

= 100

CRC = (255 - 100 + 1)

= 156

CRC = (FF - 64 + 01)

= 9C

Text Display Address and ID-Signal

The text display address and ID-Signal are transmitted in Byte 2 of the send telegram
(slave address/ID-Byte). Coding is as follows:

Text display address ID-Signal

7 6 5 4 3 2 1 0

Slave address Bit / ID-Byte

Address 1

0 0 0 0 1 0 0 0 ID-Signal 0

Address 2

0 0 0 1 0 0 0 1 ID-Signal 1

. . . . . . . .

Address 31 1 1 1 1 1 1 1 1 ID-Signal 7 = Global Call

START

> 255

- 256

> 0

CRC = 0

CRC = 255 -

+ 1

END

yes
