Input/Output Devices

The PK-88 can be used with any standard ASCII data terminal or computer equipped with
an RS-232C serial data port and a communications program or terminal emulator. Data and
control signals are exchanged between the PK-88 and the computer 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 devices
provide the means to store messages received and retrieve messages for transmission.
Although highly desirable, these peripheral or I/O devices are not needed for PK-88 opera-
tion.
Note: In this Operating Manual, 'computer' and 'terminal' mean the same thing - the key-
board and monitor or printer with which you communicate with the PK-88.

System Transmitter/Receiver Performance Requirements

Most modern radio transceivers are capable of excellent Packet-Radio performance. Radio
switching and other delays can be compensated by parameter value adjustments to the PK-
88.
The PK-88 provides software-controlled timing variations that permit operation with almost
all HF and VHF/UHF radios in general use today.
