2.3 Connecting Your Computer or Computer Terminal
MAKE SURE THE PK-232 AND YOUR COMPUTER ARE SWITCHED OFF
o Locate the PK-232 Serial Cable. Connect the 25-pin Male connector to the RS-232
I/O connector on the rear of the PK-232. If you are not using an AEA RS-232 cable,
make sure that the cable you are using has no other pins than 1-8 and 20 con-
nected.
o Connect the other end of this cable (Female DB-25) to the RS-232 Serial Port of
your personal computer or Computer Terminal. Details on connecting to common
machines are listed below.
NOTE: This cable was designed to connect directly to a 25-pin IBM-PC compatible
RS-232 port. Many machines on the market today support this configuration.
Some less-common machines are listed in section 2.6. Please make certain
you have properly connected the PK-232 to your RS-232 computer or Com-
puter Terminal then proceed to section 2.4.
2.3.1 IBM-PC/XT/AT and Compatibles
IBM compatible 25-pin RS-232 serial ports should connect directly to the supplied serial
cable. Some IBM compatible machines are equipped with a 9-pin serial port. For these
machines a DB-9 to DB-25 adapter should be obtained from a Radio Shack store or a
computer dealer.
2.3.2 Apple Macintosh Series of Computers
Timewave does not sell a terminal program for Apple computers. A few third-party pro-
grams are available and can be found by searching the World Wide Web.
2.3.3 Computer Terminal
If you have an RS-232 Computer Terminal, sometimes called a Dumb-Terminal, Smart-Ter-
minal or ASCII-Terminal, you may need to change the gender of the cable provided with
your PK-232. This can be accomplished with an inexpensive double-male RS-232 gender
changing adapter available from Radio Shack and other computer dealers. The Radio
Shack part number is 26-243.
2.4 Setting Up Your Communications or Terminal Software Program
If you will be using your PK-232 with a Computer, you will need to read parts of this section
to set up your Communications or Terminal Program Software. If you will be using your PK-
232 with a Computer Terminal you will not need any software and may skip to section 2.5.
Setting up a Communications program for your PK-232 is very important.
How your screen looks when you use your PK-232 depends completely on your Communica-
tions program. AEA currently makes available programs for the IBM-PC and compatibles, the
Apple Macintosh and the Commodore 64/128 computers. These products are customized for
radio communications and are available at extra cost from your AEA dealer.
The PK-232 operates in much the same manner as a telephone modem and most telephone
modem Terminal Programs will control a PK-232 quite nicely. Some of these programs are
"Public Domain" which means they are FREE. Other Terminal Programs are "Share-ware"
which means you may get them from a friend and try them before you buy them. Whether
