UR7HCPXZ-S440-FG

Advanced “Click-to-Select” No-DriftTM Pointing Stick Controller

Semtech Corporation 

BUILT-IN FEATURES

Semtech utilizes the scroll button to

switch the PixiPointTM Z from normal

operation mode to scroll mode.

When scroll button is pressed, the

UR7HCPXZ-S440 will convert the Y-

axis data to Z-axis data (scroll data)

and output zero motion for X-axis

and Y-axis. When the scroll button

is released, the UR7HCPXZ-S440

outputs X/Y motion data and zero

displacement for Z-Axis.

Tap — Select.

Double Tap — Execute.

Press Hold — Drag.

EasyDragTM — reduces the speed

of the cursor when the user is

dragging an object on the desktop,

making it simple to accurately

handle the object.

CleanStopTM — ensures that the

cursor stops the instant the user

needs it to.

No special drivers are needed to

access any of these features.

Scrolling (MouseWheel) operations

require IntelliMouse-compatible

Driver with Plug-n-Play support.

POWER CONSUMPTION

The UR7HCPXZ-S440 typically consumes less than 3mA. Low-power

consumption makes it suitable for use in battery-operated systems.

SERIAL COMMUNICATION

Communication through the serial port is uni-directional at a fixed speed of

1200 Baud, 7N1 protocol (7 data bits, 1 stop bit, no parity check).

The Host can reset the device at any time by setting the RTS line High.

When RTS is set Low after a delay of at least 100ms, the device will

respond with an Identification and Plug-n-Play strings. This procedure is

known as “RTS Toggle Handshaking.” When RTS goes low, the device will

send the ID characters “MZ” (0x4D, 0x5A) indicating wheel capability to the

Host. Then a ZERO motion report (0x40, 0x00, 0x00, 0x00) is sent as a

separator, followed by the Plug and Play string

“vvPNP0F0A\\MOUSE\PNP0F0A\USAR SERIAL PIXZ MOUSEcc.”

Plug and Play is a sequence of ASCII characters with their codes reduced

by 0x20. Note, vv is a version number, 2 Bytes, and cc is a Check Sum, 2

Bytes. For further information, please refer to “Plug and Play External COM

Device Specification,” available from Microsoft.

4-Byte Data Report is sent if motion is detected, or if buttons are pressed or

released. Motion is reported relative to the last Report sent, in a Two’s

Complement form and eight (8) bit resolution. In other words, the Maximum

Motion values are -128 to +127, saturated at min/max for faster speeds.

Z3-Z0 is Z-displacement. It is 4-bit Two’s Complement value from -8 to +7.
