RoadRunners – Communication Protocol
5/ Commands
This field contains the commands, its length must be the one specified in the Size field.
There are three types of commands:
5.1/ Set Config (Type "B")
This command is made up of 1 or 2 bytes. The first one contains information for
configuration of general options (common to all the symbologies). The second one, optional,
relates to specific options to each symbology.
For a Set Config (type "B") with a SELECT ALL (header "A"), the command sent can only
be 1 byte long.
Note: A high level bit ("1") corresponds to an Enable, a "0" bit means Disable.
BYTE 1 (general options):
The format of this byte is the same for all symbologies.
LSB
MSB
(1): If Min. length is enabled without having been set with the special command, the default
minimal length will be 6 characters for all symbologies.
(2): This option will not have any effect on symbologies that require a checksum (EAN/UPC,
code93, Code128). Concerning the symbologies that allow two check digits (MSI, code11),
the first check digit is obligatory. Thus, this option will affect the calculation/non calculation
of the second check digit.
(3): If Max. length is enabled without having been set with the special command, the default
minimal length will be 32 characters for all symbologies.
BYTE 2 (specific options) :
Each symbology will have a different configuration of this byte, depending on the specific
options available on each.
