Operations on the Receiver and Cable Connections

Connect the receiver and the computer in order to display on the computer the various data measured on
the receiver itself.

Connect the receiver to your PC with an RS-232C cable.

Before making or changing connections, switch off the power and disconnect the power cord from
the power outlet. Plugging in components should be the last connection you make with your
system.

• When using a notebook computer or other computer without an RS-232C terminal, this application can

be used by connecting the receiver via USB using a commercially available USB-RS-232C conversion
cable (USB-Serial cable). When using USB connections, be sure to select the proper COM port
number for data transmission (see

• The type of cable to use is a female-female cross cable. Different manufacturers use different names to

refer to this type of cable. Sometimes it is called an “interlink” cable, and sometimes it is called a
“reverse” cable.
