Parameter
base address
All data sent in
exclusive message are
given
particular
addresses
to identify
parameters. These
addresses
are
the sum of
the base address and offset
address.
Some parameters are
defined using
multiple offsets.
The address included
in
the
message of a
data set or a data
request must
be
within
the
value
shown in
the
table
below.
Note :
A
pair
of two addresses
preceded by
the symbol
#
represents a
divided
-by
-two data. e.g. the data
ABH
(hex) is
divided
into OAH
and
OBH
and
sent in that order.
Note : Parameters
associated with
address
following
the symbol %
are for
JV-80
and invalid
with
the
JV-880.
