A:
Command
set
of
CaMate
Protocol:
To
avoid
communication
conflicts
when
several
devices
trying
to
send
data
at
the
same
time,
all
transmission
and
reception
are
controlled
by
the
host
computer.
The
basic
form
is
a
command/response
protocol
with
the
host
initiating
the
sequence.
When
the
CaMate
devices
are
not
transmitting,
they
are
in
the
listening
mode.
The
host
sends
a
command
to
CaMate
with
a
specified
address
and
waits
a
certain
amount
of
time
for
the
CaMate
devices
to
respond.
The
format
for
a
command
is:
Byte1
Byte2
Byte3
Byte4
Byte5
Byte6
Byte7
Byte8
Sync
Byte
Address
Command
Data1
Data2
Data3
Data4
Checksum
All
values
below
are
shown
in
hexadecimal.
The
synchronization
byte
is
always
0xFF.
The
address
is
the
logical
address
of
the
CaMate
being
controlled.
The
checksum
is
the
8
‐
bit
sum
of
the
payload
bytes
(bytes2
through
7)
in
the
command.
