The
Read Report Command
(EBh)
prompts the PixiPoint
TM
Z for
a report. The report occurs even if
the device has not moved or if the
status of the switches did not
change.
The
S et Inc remental S tream
Mode Command (EAh)
sets the
PixiPoint
TM
Z to Stream Mode and
disables the device.
The
S tatus Request Command
(E9h)
returns a 3-byte status
report.
The
S et Resolution Command
(E8h)
controls resolution, the
S et
2:1 S c aling Command (E7h)
enables a coarse/fine tracking
response, and the
S et 1:1 S c aling
Command (E6h)
enables the
values of movements to be
transmitted to the host without any
scaling. Due to Semtech
’
s
Advanced Motion Algorithm, Set
Resolution and Scaling Commands
are acknowledged and reported as
activated, but their status is
ignored.
When the
Reset Command (FFh)
is received, the UR7HCPXZ-P440
sets the following default
parameters: Incremental Stream
Mode, 1:1 scaling, report rate of
100 Hz, and disabled. It then
sends AAh to the host followed by
a device ID of 00h.
The host sends the Resend Last
Data Stream Command (FEh) when
it detects an error in any
UR7HCPXZ-P440 transmission.
The device then resends the last
output data packet to the host.
This transmission occurs after a
PixiPoint
TM
Z transmission and
before the host enables the
interface allowing the next
PixiPoint
TM
Z output.
The
S et Default S tatus
Command (F6h)
re-initializes the
device to its condition at power-up.
The
Disable Command (F5h)
stops the device from transmitting
all reports. However, the mode
does not change; the PixiPoint
TM
Z
is still able to respond to
commands. If the Disable
Command is issued while the
device is transmitting a report, the
UR7HCPXZ-P440 immediately
stops the transmission and
disables itself.
The
Reset Ec ho Mode Command
(ECh)
returns the device to its
previous mode, and disabled.
The
S et Prompt (Remote) Mode
Command (F0h)
sets the device
to Prompt Mode. Data values are
then only reported in response to a
Read Report Command (EBh)
.
If the
S et Ec ho Mode Command
(EEh)
is received, the PixiPoint
TM
Z
will immediately return any data
bytes except FFh or ECh.
If the PixiPoint
TM
Z is in Incremental
Stream Mode, the
Enable
Command (F4h)
will allow it to
begin data transmission. If the
device is in Prompt Mode, the
Enable Command will only update
the internal status of the PixiPoint
TM
Z.
The PixiPoint
TM
Z will respond to the
S et S ampling Rate Command
(F3h)
in both Stream and Prompt
Modes but will only update its
internal status if this command is
enacted while the device is in the
Stream Mode.
The UR7HCPXZ-P440 responds to
the
Read Devic e Type Command
(F2h)
with the device ID of 00h.
