4.3.4 PM3 Communication Setting Dialog

The PM3 Communication Setting dialog is available under the IPE Menu bar, Settings menu only when the associated check box for Allow “Communication” under Settings menu is selected in the Advanced Mode, Production Mode dialog.

The MPLAB PM3 must be connected to the PC, using the appropriate cable, prior to using the PM3 Communication Setting dialog.

This dialog enables selecting the communication port for the MPLAB PM3 programmer through the IPE.

To use the RS-232 port on the MPLAB PM3, select the COM Port option and use the drop list to select the available port. Click the refresh button if necessary to view available ports. Click the Test button to check communication between the IPE and the MPLAB PM3.

To use USB for the communication port, select the USB Port option.

On some systems, you may need to set up the communications port manually.

On Windows, from the Start menu, select Control Panel, then System and Security. Under the System settings, click Device Manager. Expand the Ports drop-down list and double-click on the port you are trying to use. Click the Port Settings tab, and select the following:

Bits per second: 57600 (baud rate)
Data bits: 8
Parity: None
Stop bits: 1

Click Advanced. Uncheck the Use FIFO buffers check box.

Reboot the PC to implement the change.
