2.3 Connecting Your Computer or Computer Terminal
MAKE SURE THE PK-900 AND YOUR COMPUTER ARE SWITCHED OFF
o Locate the PK-900 Serial Cable. Connect the 25-pin Female
connector to the RS-232 connector on the PK-900 rear panel.
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 be certain you have properly connected the PK-900 to
your RS-232 computer or 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
AEA presently sells the program MacRATT with FAX which contains the
serial cable for the newer models of the Macintosh (models Mac + and
later). If you intend to use another communications program with the
PK-900 a Modem adapter cable must be purchased from your Apple
dealer to connect the Mac to your PK-900. For the newer machines
such as the Mac +, Mac SE and Mac II, a mini-8 to DB-25 adapter cable
is required (included with the AEA MACRATT with FAX program). For the
older Mac 128 and 512 machines, a DB-9 to DB-25 adapter cable from
your Apple dealer is needed.
2.3.3 Commodore 64 and 128 Computers
The Commodore 64/128 computers do not have an RS-232 port as standard
equipment. For these machines RS-232 adapters are available from
manufacturers such as Commodore or OMNITRONIX. These may work with
modem or terminal programs for your Commodore. Section 2.4 of this
chapter deals more with programs for personal computers. The AEA
Program COM-PAKRATT With FAX is NOT recommended for the PK-900.
