NAME
EXPLANATION
SAV
start of active data; see Table 21
SDID
sliced data identication: NEP(1), EP(2), SDID5 to SDID0, freely programmable via I2C-bus subaddress
5EH, D5 to D0, e. g. to be used as source identier
DC
Dword count: NEP(1), EP(2), DC5 to DC0. DC describes the number of succeeding 32-bit words:
For SAV/EAV mode DC is fixed to 11 Dwords (byte value 4BH)
For ANC mode it is: DC = 14(C + n), where C = 2 (the two data identification bytes IDI1 and IDI2) and
n = number of decoded bytes according to the chosen text standard.
It should be noted that the number of valid bytes inside the stream can be seen in the BC byte.
IDI1
internal data identication 1: OP(3), FID (eld 1 = 0, eld 2 = 1),
LineNumber8 to LineNumber3 = Dword 1 byte 1; see Table 21
IDI2
internal data identication 2: OP(3), LineNumber2 to LineNumber0,
DataType3 to DataType0 = Dword 1 byte 2; see Table 21
Dn_m
Dword number n, byte number m
DDC_4
last Dword byte 4, note: for SAV/EAV framing DC is xed to 0BH, missing data bytes are lled up; the ll
value is A0H
CS
the check sum byte, the check sum is accumulated from the SAV (respectively DID) byte to the DDC_4 byte
BC
number of valid sliced bytes counted from the IDI1 byte
EAV
end of active data; see Table 21
