Appendix C — Serial Port Compatibility
(For Anritsu Power Meter 1.0 Only)
The Anritsu Power Meter 1.0 application requires that the serial ports between COM1 and COM16 be used. You can find out the COM port number by going to Start Settings Control Panel System Hardware Device Manager Ports (COM & LPT). Disconnect and reconnect the power sensor’s USB cable from the computer and notice the new COM port number that appears in the Ports list.
Figure C-1. Device Manager
If this number is less than 16, then the PC application will work fine. However, in some cases when the power sensor is connected, Windows may map your serial port to a port number greater than 16, such as COM17 or COM29 depending on which USB port that is being used. If you connect your power sensor and the Anritsu Power Meter application displays No Sensor, a port number above COM16 may be assigned. To correct this problem, you will need to follow one of the two steps outlined below. Whichever method you use, you should only need to perform the procedure once.
