1.4.1
Input/Output Devices
Your PK-232 can be used with a standard ASCII communications terminal or computer
equipped with an RS-232 serial data port and an ASCII communications program or termi-
nal emulator. Data and control signals are exchanged between the PK-232 and the com-
puter or terminal at standard RS-232C (CCITT V.24/V.28) levels.
Your computer and terminal program and their associated tape, disk and printer I/O devi-
ces provide the means to store messages received and retrieve messages for transmis-
sion. Although highly desirable, these peripheral or I/O devices are not needed for PK-232
operation.
NOTE:

System Transmitter-Receiver Performance Requirements
Most modern radio transceivers are capable of excellent performance in Morse, Baudot
and ASCII RTTY, AMTOR and Packet-Radio. Although AMTOR Mode A (ARQ) operation im-
poses more demanding switching speed requirements than the other operation modes,
most radios will operate in either AMTOR mode without any modifications. Radio switching
times are less critical in Packet-Radio operation. See the AMTOR operating section for fur-
ther details on timing requirements.
Your PK-232 provides software-controlled timing variations that permits operation with
nearly all the HF and VHF/UHF radios in general use.

In this User's Guide, the terms "computer" and "terminal" mean the same
thing - the keyboard and monitor you use to communicate with your PK-232.
