Proximity (touch state)
Packet synchronization
Table 11 Format Tablet Status Bits
<SOH>MS<CR>
Sends a continuous stream of X/Y coordinate data when you touch the sensor. The
controller continues to send data as long as you touch the sensor. The controller sends the
data even if the touch is stationary and unchanging.
The format of the coordinate data depends on the last format command received by the
controller.
<SOH>0<CR>
<SOH>NM<CR>
This
string contains the controller model number and current firmware revision
number. The content and format of this command can change and therefore is not
intended for normal customer use.
<SOH>Z<CR>
Queries the controller and waits for a response.
Use Z to determine that you are communicating with the controller or to make sure that a
utility is communicating with the controller. Using this command does not affect the
controller’s current operating parameters.
<SOH>0<CR>
command returns a string of characters to help identify the controller. The
3M Touch Systems, Inc. Proprietary Information
Values
—
1 = Sensor is being touched (a touchdown or a continued touch).
0 = Sensor is not being touched (a touch liftoff or inactive).
When the proximity bit changes from 1 to 0 (touch liftoff), the
controller outputs one final set of X/Y coordinate data with the bit
equal to 0 and the X/Y coordinate data equal to the last touch point.
Always 1.
