User’s Manual AW900R2-EVAL
5. You will need to install EvkUtilityLite.exe and zedgraph.dll on the PC. If you
attempt to select the serial converter’s COM port with the utility, you will get
a “port closed” error, but no harm will be done.
6. You will need a serial data source program installed on your PC. If you are run-
ning Windows XP, hyperterm is already there and makes a good data source.
Unfortunately, Microsoft has discontinued inclusion of hyperterm and you will
need another alternative for later versions of Windows. There are many avail-
able for free or at low cost and they may be found by Internet search. The one
we used in our setup was Tera Term, a free terminal emulator whose latest ver-
sion can be downloaded from sourceforge: ttssh2.sourceforge.jp. The terminal
emulator program should be congured to connect to the Virtual COM port of
the Serial Converter and its serial port properties like Baud rate, data bits, etc.
should match the conguration settings in the AW900R2s. It is also useful to set
local echo and CR-LF end-of-line for transmit and receive.
7. When everything is connected properly and all the software pieces are in
place, you should be able to type characters into the terminal emulator on
one PC and see them appear in the terminal emulator window on the other PC.
Tera Term also supports text le transfers if you want to send more data than
what you are willing to type or wish to explore the effect of the radio’s tuning
parameters on the data stream.
