A notebook computer has become an invaluable tool of the Systems Engineer. Connection
between the computer and the FMUX04 is very straight forward. The only hardware required
is a DB9M to DB9F adapter cable (see pinout below). The FMUX04's RS-232 Console port
acts as a DCE to the PC's DTE communications port. A convenient application, provided with
the Microsoft Windows® 98/NT/2K/XP operating systems, is "HyperTerminal™". The
settings for console port communication with the FMUX04 are 19.2K baud, 8 bits, no parity,
1 stop bit and no flow control. In the HyperTerminal program terminal window click the
"properties" icon and set the communication parameters as in the following graphics. Click
the "Configure…" button in the properties window and set the port settings. When set
properly, click "OK".

3.4 Connecting to the FMUX04
The console port on the FMUX04 is an RS-232D interface (DCE) that utilizes an RJ-45
connector. Use the configuration cable that is supplied with the FMUX04 or prepare a three
wire DB9(F) to DB9(M) cable with the following pin out:
DB9(M) signal DB9(F)
