Timewave DSP-232, Operating Manual

Page: 18 / 271

Chapter 2 Power Supply and Computer Installation
The DSP operates in much the same manner as a telephone modem so most telephone modem terminal programs
will work with your DSP. Some of these programs are in “Public Domain” which means they’re free. Other terminal
programs are “shareware” which means you may get them from a friend and try them before you buy them.
Follow the installation directions that come with the terminal program you plan to use. Once installed on your
computer, you should start the program and set its parameters to:
♦
Data Rate = 1200 bits per second (Baud)
♦
Data bits/word length = 7
♦
Parity = EVEN
♦
Stop bits = 1
♦
Duplex = FULL
♦
Handshake = XON/OFF
Note : Early version of PC PakRatt for Windows 2.0 do not list the DSP-232 in the TNC menu. To operate
your DSP-232, you will select the DSP-1232 from the TNC menu. To PC PakRatt for Windows, your
DSP-232 ‘looks’ just like a DSP-1232. Later versions of PC PakRatt for Windows have the DSP-232 listed
in the TNC menu. THIS IS THE ONLY DIFFERENCE BETWEEN EARLY AND LATE RELEASES
OF PC PAKRATT FOR WINDOWS version 2.0.
Note : as a default, the DSP provides XON/XOFF software flow-control to the computer or terminal. The
DSP command,
XFLOW
, can be turned OFF to disable software flow control and enable hardware
handshake if your computer requires it. Hardware flow control is achieved with RTS/CTS (pins 7 and 8)
of the DB-9 RS-232 I/O connector.
IBM PCs and Compatibles
Although you can use almost any terminal program with your IBM-PC or compatible computer, AEA currently sells
PC-Pakratt-II for DOS and PC-Pakratt for Windows ; programs which provide many features not available in
telephone modem programs. (Call AEA’s 24-hour Literature Request line at 800-432-8873 and leave a message.)
Of course, you already own PC PakRatt for Windows.
If you already have one of AEA’s PakRatt programs, follow the instructions in the program’s manual to install the
software on your computer. For initial checkout of the DSP, use the programs’ Dumb Terminal mode.
A partial list of PC programs tested with the DSP includes: PROCOMM Plus, LANLINK, PC PakRatt for Windows
2.0 and 1.0, PC PakRatt II for DOS, YAPP, and the terminal program included with Microsoft Windows 3.1.
Apple Macintosh and Powerbooks
Although you can use almost any Macintosh-based terminal program with your Macintosh or Powerbook, AEA
presently sells the
MacRATT program which provides many features not available in telephone modem-type
programs. Again, call or write AEA for more information.
If you already have
MacRATT , follow the program’s manual to install the software on your computer. For initial
checkout of the DSP, use MacRATT ’s Dumb Terminal mode.
As we mentioned above, an AEA program is not required to use the DSP with your Macintosh or Powerbook. A
partial list of Macintosh programs tested with the DSP includes: MAC TERMINAL, RED RYDER,
MICROPHONE II, SMARTCOMM II and MOCK TERMINAL.
System Start-up and Loop-back Tests
Make sure that you’ve connected your DSP to an adequate power supply and to the RS-232 port of your computer
or terminal.
