USER'S GUIDE PREFACE
Welcome
Congratulations!! You've purchased another fine AEA product.
PLEASE, before we go any further, may we ask you to FILL OUT AND RETURN the Warranty Regis­tration Card, which has been packed with your PK-232 system.
WE WILL NOT BE ABLE TO FURNISH YOU WITH ANY UPDATES TO THE SOFTWARE IF YOU DO NOT RETURN THE ABOVE DOCUMENT. AS NEW FEATURES ARE DEVELOPED, WE ARE SURE YOU WILL WANT TO BE ABLE TO OBTAIN THEM.
If you call for any kind of customer assistance, we'll ask you for the serial number on you warranty card. Because of the numerous situations in which our product is used by an unauthorized third party, we MUST verify that you are the licensed user. We may choose to call you at the phone number listed in our records to verify your identity. THANK YOU for your patience.
Product Update Policy
From time to time AEA will make available updates to the design of its products. These sometimes are made available to the user who has previously purchased its products. We can only tell you about these updates if we have your warrant card. PLEASE SEND IT IN if you have not already done so. Future versions of software for the PK-232 will most likely become available. AEA will make these updates available, if possible.
In Case of Trouble
Application and troubleshooting assistance may be had by calling AEA during our 8-12, 1-4:30 working hours in Seattle WA. Ask for the Customer Service Department. The phone number is (206 775-7373. Please have your product serial number and version date of the software available. The version date is on the first screen that comes up when you turn on the PK-232. We will also need to know the nature of any other equipment connected to the PK-232.
Please attempt to solve problems locally, using other hams or an AEA dealer. Substituting a PK-80 or other TNC that you know is working properly for your questionable one is a diagnostic techni­que that will check out the rest of your station. Also try running your PK-232 in another station.
If you call for assistance, please have your PK-232 up an running beside the phone. Our service technician will likely ask you to perform certain keyboard routines to aid in diagnosis. If you have a voltmeter handy, you might have the PK-232 open so you can report measurements to the service technician.
PLEASE DO NOT RETURN THE PK-232 TO US WITHOUT CONTACTING US FOR PERMISSION FIRST. WE WOULD LIKE THE OPPORTUNITY TO TROUBLESHOOT THE PROBLEM OVER THE PHONE FIRST, SAVING YOU BOTH TIME AND MONEY.
If you send us the PK-232 by UPS it must be sent to the street address - not the post office box number. The street address is:
AEA. Inc. 206 196th St. SW Lynnwood, WA 98036 USA
We will need YOUR street address for UPS return - be sure and send it.
USER'S GUIDE PREFACE
UPS Surface (Brown Label) takes 7-8 days, Blue takes 2-3 days and Red is presently available on the West Coast only. Red is an overnight service and it is expensive. Send the PK-232 in a way that it can be traced if we cannot verify receipt of shipment. We suggest UPS or insured postal ship­ment.
If the PK-232 is still under the original owners warranty, AEA will pay the cost of the return ship­ment. The current policy is that it will be returned Brown if received Brown or by US Mail; returned Blue if received Blue or by overnight service; or returned as the owner sates in his letter if he fur­nishes the return cost for the method he selects.
If the PK-232 is out of warranty, it will be returned by UPS Brown COD unless:
1) It was received UPS Blue/Red in which case it will go back UPS Blue COD, or
2) If you designate billing to VISA or MASTERCARD, or
3) you enclose a BLANK personal check endorsed "not to exceed ...$", or
4) you specify some other method of return.
We will typically service the product in two or three days if we have all the facts. If we must call you, it may take longer. PLEASE, if you send it in, include a letter stating the problem and were you can be reached. If you can be reached by phone in the evening on the east coast, let us know where. Our current rate for non-warranty service is $40/hour with a 3/4 hour minimum. Parts and shipping are extra. AEA is not responsible for damage such as caused by lightning, nonprofessional alterations, poor storage/handling, etc.
Should your warranty card not be on file at AEA, you need to send the proof of purchase date to receive warranty service. Typically a copy of your bill of sale from an AEA dealer will suffice.
The warranty is for original owner only and is not transferable.
USER'S GUIDE PREFACE
INTRODUCTION
Welcome to the exciting world of digital Amateur Radio! You've joined the ranks of the fastest growing modes in Amateur Radio since the FM repeater.
Your AEA PK-232 Data Controller is the connection between your computer and radios. The PK-232 performs all the "magic" of establishing data and text communications between your station and many other communication facilities equipped for digital communications.
With packet-Radio and AMTOR, you'll have a "private channel" while sharing a frequency with oth­er packet and AMTOR stations; you'll be able to "read the mail" of other Morse, RTTY and AMTOR QSOs. log on to computer-based "bulletin board" or "mailbox" sations, handle message traffic – in short, you're now equipped to enjoy the advantages of digital communications and error-correcting radio techniques in your ham shack.
Your new AEA PK-232 is the heart of your digital radio station. The PK-232's packet system soft­ware is derived from the original TAPR TNC; it presents many of the advenced features of that de­sign, coupled with significant enhancements based on the experience gained by thousands of TAPR-equipped amateur packet stations worldwide.
This manual is your guide into the realm of digital Amateur Radio.

Join a Packet-Radio club - they exist in all states as of this writing. You might also subscribe to the ARRL publication "Gateway", which describes all the "going on" in Packet-Radio, and to the TAPR "Packet Status Register", which describes the technically interesting happenings in the movement. There are many voice nets on VHF and HF; they usually meet weekly. They are usually dedicated to making the newcomer feel at home.

USER'S GUIDE INTRODUCTION
1.4 System Components
Your PK-232 Data Controller package contains the following items:
o One PK-232 Data Controller o Cables to connect your PK-232 to two separate radios o User Guide to the PK-232
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 termi­nal emulator. Data and control signals are exchanged between the PK-232 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-232 operation.
NOTE: 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.
1.4.2 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 im­poses 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 fur­ther 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.
PK232UG Rev. B 9/86 1-4 18
USER'S GUIDE INSTALLATION
CHAPTER 2 – INSTALLATION
2.1 "Quick Start" Installation
You'll probably want to get your PK-232 connected and operating as soon as possible. This section contains instructions for a "generic" installation and system checkout to install and verify your PK-232's operation.
More detailed installation and system checkout instructions for specific computer applica­tions are contained in AEA's Technical Manual for the PK-232.
2.1.1 Equipment Required
A complete PK-232 Data controller system consists of the PK-232 and its power supply, your computer, your radio transceiver or receiver-transmitter combination and its power supply.
AEA supplies the cables for connecting the PK-232 Data Controller to your radio and an external power supply. You must add the microphone connectors required by your radio, the power supply and the RS-232 cable that connects the PK-232 to your computer.
2.1.2 Precautions
AEA strongly recommends that all RS-232 cables and connectors be made with the best commercial-quality shielded materials and that careful and correct grounding and bonding procedures be observed in the installation of the radio equipment being used with your PK-232.
2.1.3 Installation
The following sections describe the initial settings of the switches, connectors and their connections to your computer and your radio.
2.1.3.1 Initial Control Settings
For initial power-up of your PK-232, use the following front-panel control settings:
POWER SWITCH OFF RADIO 1/RADIO 2 Radio 2 THRESHOLD Approximately "3-o-clock"
2.1.3.2 Power Connections
Power is connected to the PK-232's rear-panel coaxial power receptacle from any well regulated 12-volt DC power supply (12 to 16 VDC) capable of supplying 1 ampere. AEA's optional Model AC-4 wall adapter power supply can be used.
o Be sure your power supply can furnish one (1) ampere with ripple voltage less than
one volt peak-to-peak.
o Be sure you connect the positive voltage to the center pin of the coaxial power plug.
If you accidentally invert the power cable, an internal fuse will open to protect the PK­232 from reverse-voltage damage. If this occurs, open the PK-232 and replace the in­ternal fuse with an identical 1-ampere unit.
PK232UG Rev. B 9/86 2-1 19
USER'S GUIDE INSTALLATION
2.1.3.3 Radio Input and Output Connections (See Table 1-1)
AEA has supplied two shielded cables for connecting your PK-232 to one or two radios. One end is already pre-wired with a 5-pin Molex-type plug. You must supply and con­nect the plug for the end that connects to you radio's microphone receptacle or PTT and phone patch and tone inputs.
NOTE: Don't prepare both cables yet. Set one cable aside for use as a test cable
during your first "loopback" experiments with Packet-Radio operation.
The following signals at five-pin receptacles J4 and J6 pass between your PK-232 and radio. The pinout is shown in Table 2-1.

Table 2-1 J4 and J6 Radio Port Connectors
2.1.3.4 Computer Connections (See Table 1-2)
The PK-232's rear-panel serial-port connector carries data and control signals between your computer and the PK-232. The minimum number of pins that must be connected is shown in Table 2-2.
The PK-232 is connected to a computer just like you connect a RS-232C modem. If you now use your computer with a modem, connect the PK-232 the same way. Use any ter­minal program you now use with your modem.
IMPORTANT NOTE
If the full RS-232 cable set is used, DO NOT CONNECT any pins other than pin 1 trough 8, and pin 20! The remaining pins 17 trough 19 and 21 through 25 have been reserved for future use. Connection of a full RS-232 wire set will cause improper operation of your PK-232. The minimum connections shown do not permit hardware flow control.

USER'S GUIDE INSTALLATION
2.1.4 Controls
Your PK-232's front panel has three controls:
o POWER ON/OFF push switch - turns off power from external supply o RADIO-1/Radio-2 push switch - selects between two available I/O jacks o THRESHOLD control - squelch-like adjustment inhibits display of garbage characters
produced by received noise
2.1.5 Indicators
Your PK-232's front panel has three categories of LED (Light-Emitting Diode) indicators:
o Status o Mode o Tuning
2.1.5.1 Status LEDs
DCD Data Carrier Detect MULT Multiple Connection SEND Transmitter PTT enabled ERROR In ARQ: Receiving errors from the distant station /CONV In Packet: System is in Converse Mode IDLE ARQ and FEC synchronous idle link, no traffic PHASE ARQ phasing is active STBY Ready to receive ARQ or FEC STA Packetframe(s) unacknowledged CON Packet link is in connected state RQ In ARQ: Requests for repetition from distant station /CMD In Packet: System is in Command Mode TFC In ARQ: System is sending/receiving traffic (data) /TRANS In Packet: System is in Transparent Mode OVER AMTOR changeover

2.1.5.3 Tuning Indicator (See Figure 2-1)
This ten-segment bargraph LED display shows proper tuning of received mark and space tones in HF and VHF CW and SSB FSK or AFSK operations. In these modes, the correct tones are determined by how you tune your receiver.
PK232UG Rev. B 9/86 2-3 21
USER'S GUIDE INSTALLATION
In the absence of a received tone signal, the center LED elements are lit. When the re­ceived tone is at the "mark" frequency, the LED bars at the left side of the indicator will be lit. Received "space" tones will light the bars at the right side of the indicator. A properly-tuned RTTY, AMTOR or Packet signal will be symmetrically divided, with the brightest bars at the ends of the indicator. A properly-tuned CW signal will shift the lit bars from the center to the extreme-righthand side of the display.
In FM operation, tone frequencies are set by the transmitting station and can't be changed by the receiving station.

2.2 Serial Port Configuration
Let's verify that your PK-232's serial port and data words are set up properly for your com­puter. Should your monitor display garbled or incorrect characters or "funny" graphic sym­bols, you can change the PK-232's serial port parity and word length. The common parity and word length combinations are seven bits, even parity and one stop bit.
Your computer will probably accept the PK-232's default setting, even if it actually uses a dif­ferent setting. If your computer requires eight data bits, you may have to set parity to "none"; otherwise text may be interpreted as graphics or other special characters.
To set eight bits, space parity, type:
AWLEN 8 (8-bit words) PARITY 0 (no parity bit)
To return to seven bits, even parity, type
AWLEN 7 (7-bit words) PARITY 2 (even parity)
One of these combinations will satisfy most computers. You're more likely to require a differ­ent setting if you have a "dump" terminal rather than a computer, or if you've configured your computer's serial port for some special application. If your computer needs odd parity, set PARITY to 1.
If your computer detects framing errors, try this for shorter characters:
AWLEN 7 (7-bit word) PARITY 0 (no parity it)
For longer characters try:
AWLEN 8 (8-bit words) PARITY 1 or PARITY 3
2.3 Screen Display
Some computer and terminal programs are configured to certain default characteristics that may, at first, seem incompatible with the PK-232. Follow these hints as you begin to "dia­logue" with your new TNC.

USER'S GUIDE INSTALLATION
2.3.1 Echoes
You may see to characters on your screen for every typed character.
cmd:RREESSEETT
Both your computer and your PK-232 are echoing your typed characters.
o Type: ECHO OFF to stop the PK-232's echoes.
If you later use your PK-232 with a different computer or terminal program, you may see nothing displayed when you type. In that case, set ECHO ON.
2.3.2 Line Feeds and Carriage Returns
If the lines displayed appear to be double spaced, your computer is adding an extra line feed <LF> when it displays a carriage return <CR>.
o Set ALFDISP OFF to stop your PK-232 from adding an <LF>.
If you change equipment you may have to set ALFDISP ON to restore the PK-232's auto­matic line feeds.
2.3.3 Screen Width
The screen width default value is 80, the width of many CRT displays. The PK-232 sends an extra <CR>, or <CR><LF> if ALSDSISP is ON, when 80 characters have been dis­played on a line.
If your computer does not automatically break long lines:
o Set ACRDISP (the screen width) to the width of your display. o For a computer using a TV set for a display, set ACRDISP to 40.
If your computer does automatically beak long lines:
o Set ACRDISP to 0 to disable this feature. Otherwise, you will get two <CR> when
the line wraps around.
2.3.4 Display Speeds
A few computers will lose the first characters of a line when several lines are displayed in rapid succession.
o Give the computer more time between lines by setting NUCR ON (delay after <CR>)
or NULF ON (delay after <LF>).
The delay is adjusted by NULLS, which sets a number of character-times for the delay.

2.4 System Start-up and Quick-check
Do these steps before connecting any cables between your PK-232 and your radio.
Connect your PK-232 to your computer via the RS-232 cable. MAKE SURE THAT ONLY PINS 1 THROUGH 8 and PIN 20 are connected.
Connect you PK-232 o a regulated 12-volt DC power supply.
Set the RADIO 1 / RADIO 2 switch to RADIO 1.
Connect a wire jumper between pins 1 and 2 on the PK-232's J4, or short the two appro­priate loads on your TTL connector cables.
Press the PK-232's power switch to the ON position.
Turn on your computer. Load and run your communications program.
Set your computer's data rate to 1200 bauds, if available.
If your serial port is operating at 1200 bauds, you'll see the following message right away.
Please type a star (*) for auto-baud routine.
If this message appears, go to Step 9 now.
If you're using your computer or terminal at a different data rate, your screen may show meaningless "junk" characters. If true, go to Step 9 now.
Don't panic! - your PK-232 is doing its "auto-baud" routine with which it will measure your computer's data rate and set itself accordingly. (The PK-232 scans for baud rates of 300, 1200, 2400 and 9600 bauds.)
Type several asterisks (*) at one-second intervals.
If the cable and and connections between the PK-232 and your computer are correct, several of the PK-232's LEDs will begin cycling in order as the PK-232 run in its "auto­baud" routine. As soon as the PK-232 has recognized your data rate and set itself accord­ingly, your screen will display the sign-on message:
PK-232 is using default values.

2.7 "Quick Start" Radio Connections and Set-Up
Let's go through a simple step-by-step routine in which you'll verify that all cables and con­nectors are properly installed and that your PK-232 Data Controller is working corectly. The procedure will help you become familiar with the software commands and operations.
If you have a problem that seems unsolvable after reading this User's Guide thoroughly and checking all cables and connectors, please refer to the instructions for calling AEA in the front of this manual.
During these initial checkout procedures, do not connect the PK-232's PTT and AFSK lines to the transmitter until instructed to do so. Make all other connections as described below.
After all the cables between the PK-232, your radios and your computer have been installed, apply power to your equipment in this order: radio, computer, PK-232.
