D-LGT:
(OperatingMode.ScanMode.DataSource.NoOfBytes)
D-LGT defines the length of raw data which are transmitted in the Scan-Mode. Depending
on the used ScanMode Interface D-LGT is interpreted either in Bits or Bytes. IF Scan
Mode interface is USB or serial D-LGT is interpreted in Bytes. If Data-Clock is used as
Scan Mode Interface D-LGT is interpreted in Bits.
Case Scan-Mode via asynchronous interface:
D_LGT
= Number of
data bytes
to be transferred, started with the D_START.
Example: data block

Output Data

0x45
0x67
0x89
Case Scan-Mode via data-/clock interface:
D_LGT
=
Number of
data bits
to be transferred, started with the D_START.
0:
D_LGT = 256 bit.
1...255: D_LGT = Parameter value
In case if DB-FORMAT = ASCII format, the number of D_LGT data bits
must be multiplied with 2 to get the whole data block
