Command and Parameter Values (Code
L
)
15
H
SetPosAcknowledgelevel (as of Firmware Version 2066):
This command sets the PosAcknowledge threshold value (also see page 160). The
parameter value Code
L
is the desired PosAcknowledge threshold value in bits
[00
H
… FF
H
]. Also see comments page 253.
17
H
Store/RestoreTransmissionMode (as of Firmware Version 2078):
This command allows the currently used status return data type to be temporarily
stored (Code
L
= FF
H
) and then reinstated at a later time (Code
L
= 00
H
). Also see
Code = 0527
H
.
21
H
SetEchoMode (as of Firmware Version 2078):
This command verifies whether data transfer is intact (also see page 161). It
transfers an 8-bit value (Code
L
) to the scan system and causes a 20-bit value to be
returned on the corresponding status channel: if data transfer is error-free, then
the upper 8 bits of the returned 20-bit value will be identical with Code
L
and the
next lower 8 bits will be identical with the complement of Code
L
(NOT Code
L
).
Example: For control_command(1, 1, 0x210A) and if data transfer is error-free,
(get_value(1) AND 0xFFFF0) returns 0x0AF50.
