60 G12 OEM Board & Sensor Reference Manual
Table 4.11 defines the response format:
DSY: Daisy Chain Communications Mode
$PASHS,DSY,c1,c2;
This command redirects all characters from one serial port to the other without
interpreting them, where c1 is the source port and c2 is the destination port. Any
combination may be chosen. When daisy chain mode is in effect, the source port
can only interpret the OFF command; all other characters are redirected.
$PASHS,DSY,OFF
The OFF command disables daisy chain mode. A bi-directional daisy chain mode
(i.e. A to B and B to A at the same time) can also be enabled.
