Lexicon MC-12HD - Menu Navigation and Operation

Lexicon MC-12HD Serial Communications Protocol
Software Minor Revision: An unsigned 8 bit integer value indicating this units minor software version.
Indicates the units software operation has changed but effects, effect
parameters, or system parameters have not changed.
Protocol Major Revision: An unsigned 8 bit integer value indicating the serial communication protocol
major version. The host should use this value to determine if new
commands, notifications, or response packets have been added or deleted
from this specification.
Protocol Minor Revision: An unsigned 8 bit integer value indicating the serial communication protocol
minor version. The host should use this value to determine if the existing
commands, notifications, or response packets have changed in this
specification
Parameter Count: An unsigned 16 bit integer value indicating the maximum number of
parameters for this version of software. All Parameters are sequential
ordered with in the unit so cycling from ParamId 0 to ParamId = Parameter
Count -1 allows for the host system to learn the Parameter definitions for all
Parameters defined for a given software version. The 16 bit value is packed
LSB followed by the MSB.
Total Number of Effects: An unsigned 8 bit integer value indicating the maximum number of effects
available for this version of software.
TimeStamp: Is a null terminated ASCII text string describing the build date and time of the
current software build. The Format of this text string is:
“yy/mm/dd(sp)hh:mm”
yy- is the last two digits of the year (i.e. year 2001=01, year 2002 = 02)
mm - is the month
dd- is the day
(sp) - is an ASCII space character (0x20)
hh - is the hour
mm - is the minute
SerialNumber: The Serial Number is an unsigned 32 bit integer holding the unique value of the
current unit.
