Example:
A code carrier contains the code A011C3E3B900F0F0 in hexadecimal form. The
code shall be read by the heed 3.
In data format 10 the first 12 bits (A01h=1010 0000 0001b) are transmitted in hexa-
decimal form. The following 16 bits (1C3Eh = 0001 1100 0011 1110b) are converted
into a binary number (1C3Eh =7230d). A read head number does NOT precede the
code and hence the read head number "X" only makes sense when there is only one
read head. Consequently, in the example, the following character is sent.
No provision is made for the binary mode in data format 10.
In data format 28 the first 12 bits (A01h = 1010 0000 0001b) and the following 16 bits
(1C3Eh = 0001 1100 0011 1110b) are separately converted into denary (A01h=2561d
and 1C3Eh=7230d). The code follows the read head number and is preceded by a
space character. Hence, the following character string is sent:
In the binary mode no denary conversion takes place. The read head number is de-
termined by bits 4 and 5 of the first byte. The two most significant bits, 6 and 7, are
set at 0.
The character "X" contains the first 4 code bits.
