How do I use the LED on the PenMount controller to diagnose problems?
  • When pressing the touch panel, the LED will illuminate. When nothing is pressing on the touch panel, the LED will be dark. This indicates the circuit between “computer – controller – touch panel” is normal.
  • If the LED is constantly illuminated, the touch panel’s active area is being compressed by a mechanism or object or there is a pin correspondence error between the touch panel and controller.

(Remark: if the driver for the PenMount 6000 RS-232 has not been installed, the LED will be constantly illuminated.)

  • When pressing the touch panel, if the LED does not illuminate, the following reasons may be the cause: no power supply, touch panel malfunction, controller malfunction, connector error, or operation is occurring on the wrong side of the touch panel.

When using PenMount products with a RS-232 (UART) interface, why does the system indicate no device detected or is unable to operated device?

You can first confirm the system’s COM Port is operating normally or use the following PenMount provided testing software to determine whether the COM Port is occupied by other software or drivers:

Step 1: Connect the PenMount device to the COM Port.

Step 2: Uninstall PenMount RS-232 driver to prevent the driver occupying COM Port resources.

Step 3: Use the following testing tool accoding to operating system to determine whether COM Port resources are normal:

Operating SystemTesting SoftwareCommand
Windows XP/ 7/ 8232nt.exeC:>232nt com1 19200
Linuxpm_sniff#./pm-sniff /dev/ttyS0 19200
Dos232.exeC:>232 com1 19200

Remark: Please set according to your hardware baud rate and enter 19200 or 9600.

Step 4: After executing the aforementioned software, when you press the touch panel, touch data will be sent and indicate your COM Port is normal.  If no signal appears, COM Port resources may be occupied, making the PenMount driver unable to communicate with the PenMount hardware device.
