PK-232 TECHNICAL MANUAL
1.1
Introduction
This Technical Reference Manual will assist you to maintain, repair and adjust your PK-232
Data Controller. Please use this manual in conjunction with AEA's Operating Manual for the
PK-232, Revision D.
The PK-232 Operating Manual contains complete and detailed information on controller op-
erating procedures, controller commands and syntax, general installation methods, terminal
and radio connections, as well as connector wiring diagrams, printed circuit board sche-
matics, board layout drawings and parts list.
1.2
Scope
This manual includes information on theory of operation, hardware descriptions and trouble-
shooting instructions and charts. In addition, detailed information on the PK-232's Host
mode is presented for the benefit of programmers and software application developers.
1.3
General Description
AEA's Model PK-232 is a multi-mode protocol converter and data controller that includes
self-contained modems for all modes.
The PK-232 sends and receives Morse Baudot and ASCII RTTY, facsimile, AMTOR/SITOR and
AX.25 packet. The PK-232 converts these signals to ASCII data end sends the data to your
terminal via an EIA standard RS-232 (CCITT V.24/V.28) serial port, and to your printer via a
special Centronics-type parallel interface. Except for the printer interface, the reverse proce-
dures convert ASCII data typed at your terminal to the signals and protocols required for
transmission to other stations.
All necessary tone generation and demodulation (modem) functions are built in; however,
external modems can be connected to the PK-232 via dedicated rear-panel connectors. All
decoding, encoding, protocol and transmitter control routines are stored in the PK-232's
firmware in PROM and internal program memory.
Operating modes, speeds, modem tone pairs, filter bandwidths and system protocols are se-
lected by typing commands on your computer or data terminal. Any communications or ter-
minal emulator normally used with a telephone line modem can be used with the PK-
232.
