COM PORT
The Programmer software communicates with the encoder through the encoder IR port using the IR programming and data
profile cable (IR cable) . You must identify the correct communication (COM) port for the IR cable to make sure the software
can communicate with the encoder . Follow these steps to identify the correct COM port for the IR cable connected to
the computer .
1 . Connect the IR cable to the serial port of the computer . If the computer does not have a serial port, use a
serial-to-USB adapter .
Follow these instructions to identify the COM port:
• Select the Microsoft Start button .
• Right-click on Computer* .
• Select Manage .
• Select Device Manager from the menu
on the left .
• In the Device Manager window, click
