Return/Repair Procedures
.........................
Consult the limited warranty policy in this manual for the service provisions offered by
Kantronics at no charge. This warranty is considered to be in force only when the customer
has submitted his completed warranty registration within 10 days of purchase, and when the
stipulations of the warranty have been met. Violations of warranty clauses will automatically
void the warranty and service or repairs will be charged to the owner.
Service outside the warranty will be charged at the cost of parts, labor, and return shipping.
Units returned for service without a Return Authorization number will be subject to a
minimum charge of 1/2 hour labor plus shipping and handling. Contact the Service Department
(913-842-4476) to obtain a Return Authorization number. Repaired units will be returned via
UPS C.O.D. These C.O.D. charges can be avoided by including your VISA or MasterCard
number with your unit to be repaired. Shipping and repair may then be charged.
When service or repairs appear necessary, it may be wise to call or write Kantronics to
determine if the problem can be solved without returning the unit. Should you encounter
difficulty in getting your RAM Plus to "talk" to your computer, you may wish to perform some
limited checks before calling or writing. Carefully check your wiring connections to the RS-232
port. Verify your terminal baud rate. It may be useful to perform a "Hard Reset". (See Hard
Reset section.)
When calling, report the product name and ask for the Amateur Radio Service Department.
Should you find it necessary to call for assistance, please have the following information
available:
1. The unit name and serial number (the serial number is found on the rear panel.)
2. The firmware version number (the version number is displayed when you give
the Version command.)
If possible, you should have the KAM Plus and your computer available to perform
troubleshooting operations when you call.
The Service Department telephone hours are 9 am - noon and 2 pm - 5 pm
Central Time 913-842-4476, Monday through Friday.
When writing, include a clear description of the problem, unit name, computer type, computer
software used and if possible a DISPLAY listing from the KAM Plus.
Returns to the factory for refund or exchange are strictly regulated. Any return for refund or
exchange must be approved by the service department.
Additional International Support

Radio Frequency Interference Statement
INFORMATION TO THE USER
NOTE: This equipment has been tested and found to comply with the limits for a Class B
digital Device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equip-
ment generates, uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced Radio/TV technician for help.
The user is cautioned that any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
The user is also cautioned that any peripheral device installed with this equipment must be
connected with a high-quality shielded cable to insure compliance with FCC limits.

In moving to the world of digital communications via computers, a new dimension of RFI
may be encountered. In spite of the equipment manufacturers' diligence, each new piece
of electronic equipment will react differently in each separate environment. Every amateur
station will have its own unique layout, equipment variation, and antenna installations.
Experience has shown that these differences are related to the total RF environment, and
may be causative factors in RFI induced problems. The suggestions given here may assist
in resolving RFI problems you may encounter in your "unique" station.
1. Use shielded cable for all connections between equipment.
2. Make all interconnecting cables as short as practical. A balance should be maintained
between cable length and equipment proximity. At times simply moving the video monitor
one foot further from an interface or other device will solve the "screen hash" problem.
3. Antenna runs should be kept away from equipment control lines and/or interconnecting
cables. If it is necessary for such lines to cross each other they should do so at 90 degree
angles.
4. Ground leads should be as short as possible and go to a GOOD EARTH GROUND.
5. Interconnecting cables appearing to act as radiators or antennas should be looped through
a toroid. Be certain toroids, if used, are designed for the frequency in use.

Introduction to Commands
Some Abbreviations
<Ctrl-x>: This represents a single control character sent from your terminal program to the
RAM Plus. To send this character, press and hold the control key and type the second key (x)
while holding the control key down. If another letter follows this (i.e. <Ctrl-C>T) do not con-
tinue to hold the control key down while pressing the other letter. If your keyboard does not
have a control key, consult your computer/terminal manual to determine which key performs
the control key function. If your terminal does not have a key that performs this function, you
will need to change the parameters in the RAM Plus that define these special Ctrl key
characters.
$ preceding a number denotes a hex number (base 16)
<CR>: carriage return, $OD, decimal 13, <Ctrl-M>, ENTER key
<LF>: line feed, $OA, decimal 10, <Ctrl-J>
va: InpuUOutput
Entry
A command is entered to the RAM Plus by typing the command name and its argument
(setting or value) in the Command mode. The prompt for the Command mode is cmd:.
The command name and the argument must be separated by a space, and the KAM Plus takes
action when a carriage return <CR> is typed. All commands may be abbreviated to the shortest
string indicated by the CAPITAL letters in the command reference.
You may examine the value of any parameter by typing the command name followed by a
<CR>. The DISPLAY command allows you to display sets of related parameters as a group.
Format
All commands are listed alphabetically in this manual. On the first line of a command will be
the command name followed by any arguments used with the command. Arguments shown in
square brackets ([ ]) are optional. If a command accepts several different values, or a range of
values, the permissible values will be shown in parentheses ( ). Arguments may also be shown
separated by a vertical bar (I). This indicates that you may choose ONE of the items separated
by the bar. The factory default value for this parameter or command is shown in curly braces
(( )).
Some of the commands in the RAM Plus are dual-port commands, allowing you to set one value
for the HF port of the RAM Plus, and a different value for the VHF port. This is indicated by a
dual-port default value (e.g. (192/63)). The value shown before the slash bar is the value used
for the HF port of the RAM Plus, and the value after the slash is used for the VHF port. There
are a few exceptions to the HFNHF convention, in which the value before the slash applies to
non-packet modes of operation, and the value after the slash is for packet operation. These are
noted in the description of the command.
Parameter Types
n (range): Any number within the range is permissible.
n($00 - $FF): Any HEX number - normally used to define an ASCII character. When entering
a HEX number, be sure to type the $ symbol to indicate a hex number follows. See the ASCII
chart at the end of the manual to determine the code required.

flags (choiceAlchoiceB): Many commands allow a choice of two or more possible entries
(e.g. ON IOFF). For ON/OFF choices, you may also enter YES or NO. Other commands accept
one of several choices (ON IOFF ITO IFROM). Enter the appropriate word to indicate your
choice.
callsigns xxxxxx-n: Many commands require a call sign or alias as an argument. These
parameters are normally set to Amateur callsigns, however any combination of 6 numbers
and/or letters is permitted. You may optionally include an "extension" (SSID, Secondary
Station Identifier) which is a decimal number between 0 and 15 (inclusive) used to distinguish
two or more stations on the air with the same amateur call. SSIDs of 0 are not displayed by the
KAM Plus.

after it has received the MYAUTOST identifier. It will then continue to receive until it receives
four "N"s signifying the end of message, or 30 seconds of no signal.
When ON and in AMTOR mode or FEC mode, only AMTOR SELFEC messages which contain
any of the selcals in MYSELCAL or MYGROUP will be received. Loss oflock will cause the
RAM: Plus to stop receiving data. See also: fec, myautost, mygroup, myselcal.
• AX2512v2 ON IOFF {ON/ON}
When ON, Level 2 Version 2 protocol is implemented for packet operation. When OFF, Level 2
Version 1 protocol is used. See also: relink, retry, tries
For more information, the book AX. 25 Amateur Packet-Radio Link-Layer Protocol Version 2.0
October 1984, can be obtained from the ARRL.
• AXDelay n (n =0 - 255) (O)
This command specifies a period of time to wait, in addition to TXDELAY, after keying the
radio before data is transmitted. If you operate through a voice repeater, this delay may be
required to allow the repeater's transmitter to turn on. Each unit represents 10 milliseconds.
• AXHang n (n =0 - 255) (O)
When operating through a voice repeater, this command should be set to the hang time
of the repeater. If the KAM Plus has detected activity within this time interval, it will not use
the AXDELAY setting, since the repeater should still be transmitting. Each unit represents
10 milliseconds.
• Beacon [Every IAfter] n (n =0 . 255) (EVERY O/EVERY O)
When set to EVERY, a beacon packet will be transmitted every n minutes. When set to AFTER,
a beacon packet will be transmitted ONCE after n minutes of no channel activity. Setting n to 0
will disable beacon transmissions. See also: btext.
• BIts n (n =$00 . $FF) {$OO}
This command specifies the bits to be inverted when receiving a RTTY or ASCII signal. This
may enable you to decode some scrambled RTTY/ASCII signals. Transmitted RTTY and ASCII
is not affected by this command.
• BKondel ON IOFF (ON)
When ON, the KAM Plus will echo a backspace-space-backspace sequence to your terminal
when the DELETE character is received from the terminal. When OFF, the RAM Plus will echo
a backslash character (\) when the DELETE character is received. See also: delete, redisplay.
• BText text (0 - 128 characters)
Specifies the contents of a BEACON packet. To clear the BTEXT, enter a single %character
(BTEXT %). See also: beacon.
• BUDCalls [+ I-]callsign(s) I NONE (NONE)
A list of up to 10 callsigns for use with BUDLIST or CONLIST. To delete or add individual
entries, precede the call sign with a "-" or" +" respectively. See also: budlist, conlist.

COMMANDS
9

• BUdlist OFFITOIFROMION {OFF/OFF}
When OFF all packets are eligible to be displayed as monitored packets. When ON, only those
packets TO or FROM stations listed in the BUD CALLS will be monitored. When TO, only
those packets addressed TO stations in the BUDCALLS will be monitored, and when FROM,
only those packets FROM stations listed in the BUDCALLS will be monitored. See also:
budcalls, monitor, suplist.
• CALibrat {immediate command}
The CALIBRATE command is used to generate a signal which may be used as an aid in
tuning the transceiver for operation with the KAM Plus. Use of this command is detailed
in the Calibration/Equalization section of this manual. The letter X will return you to the
Command mode.
• CAnline n (n =$00 - $FF) ($I8 <Ctrl-X»
When entering commands or data to the KAM Plus, you may cancel the current line you are
typing (back to the last un-passed carriage return) by sending a <Ctrl-X> to the KAM Plus
from your terminal. When operating non-packet modes, a <Ctrl-X> will clear the transmit
buffer of any characters you have typed which have not already been transmitted over the
radio. See also: can pac, cpactime, pass.
• CANPac n (n =$00 - $FF) ($I9 <Ctrl·Y»
When entering commands or data to the KAM Plus, you may cancel the entire packet (back
to the last un-passed SEND PAC character) by sending a <Ctrl-Y> from the terminal to the
KAM Plus. When in Command mode, <Ctrl-Y> acts as a cancel output character, turning off
any output from the KAM Plus. Typing another <Ctrl-Y> re-enables output. See also: canline,
cpactime, sendpac.
• CD INTERNAL IEXTERNAL ISOFTWARE {INTERNAUINTERNAL}
When set to INTERNAL, the KAM Plus will detect a signal when any energy is present on
the audio input to the KAM Plus. When set to EXTERNAL, the signal detection is supplied
by an external device, connected to the XCD pin of the radio port. When set to SOFTWARE,
the firmware in the KAM Plus will detect a signal based on the presence of Packet data on
the audio input. This setting allows open-squelch operation. Proper equalization is important
for correct operation of software carrier detection.
When operating RTIY or ASCII, the KAM Plus will use only INTERNAL or EXTERNAL. If
this command is set to SOFTWARE, the KAM Plus will act as though it were set to INTERNAL
when operating these modes. See also: swp.
• CHeck n (n =0 - 255) {OJ
This command specifies the time interval, in 10 second increments, used to check the condition
of a packet connection if no data is passing between the connected stations. IfAX25L2V2 is
ON, the RAM Plus will send a "check" packet every n *10 seconds to insure the other station
is still responding. IfAX25L2V2 is OFF and n *10 seconds has passed with no data being
transferred, the RAM Plus will send a disconnect to the other station. Setting CHECK to 0
disables the automatic check function. See also: ax2512v2, kntimer, relink, rnrtime.
• CMdtime n (n =0 - 15) {I}
This command sets the permissible time (in 1second increments) between characters when
attempting to exit from the Transparent mode. WARNING: Setting CMDTIME to 0 will
prevent you from exiting the Transparent mode. See also: command, trans.

• CMSg ON IOFF IDISC IPBBS (OFF/OFF)
When OFF, the custom text stored in CTEXT w:illnot be sent to a connecting station. When
ON, the custom text w:illbe sent. When set to DISC, the custom text will be sent, and then
your KAM Plus w:ill disconnect from that station. When set to PBBS, the custom text will be
sent to the connecting station, and then the connection will automatically be transferred to
your PBBS, ifit is available. If the PBBS is not available, the KAM Plus will disconnect from
the station. See also: ctext, pbbs.
• CODe [AMTOR IRTTY] [ITA21US ILCRTTY IAPLINK IMARS]
{AMTOR ITA2/RTTY ITA2)
This command allows you to select the alphabet used to send and receive RTTY and AMTOR.
ITA2 uses the International Telegraph Alphabet Number 2, US selects the U.S. character set
(not available in AMTOR), LCRTTY provides a complete upper/lower case character set, and
APLINK uses the full printable character set developed by G3PLX and W5SMM (currently
used on APLINK BBS systems). When set to MARS, special characters can be used as required
by the Military Affiliate Radio System. (See the MARS Feature section of this manual.)
• COMmand n (n =$00 . $FF) ($03)
This command sets the character used to enter the Command mode from the Convers mode,
or to exit from the Transparent mode. It also defines the lead-in character for non-packet mode
directives.
• CONList ON IOFF (OFF/OFF)
When ON, the KAM Plus w:illrecognize only those packets received with a call sign that
appears in the BUDCALLS list. All other packets are completely ignored. When OFF, packets
originating from any station are accepted. See also: budcalls.
• CONMode CONVERS ITRANS (CONVERS)
This command sets the mode the TNC w:illbe placed in AUTOMATICALLY when a connect
occurs ifNOMODE is OFF. See also: canline, connect, convers, nomode, trans.
• Connect callI [VIA ca1l2,ca1l3, ...ca1l9] (immediate command)
This command is used to initiate a packet connection to another station. Each callsign may
have an optional ssm specified as -n where n =I to 15. Ca1l2 through call9 are used to specify
digipeaters required to connect to a distant station.
This command can also be used to reconnect through a different set of digipeaters to a distant
station you are already connected to. See also: conmode, conok, maxusers, nomode, retry, ring,
streamsw, xmitok.
• CONOk ON IOFF (ON)
When ON, connect requests from other TNCs will automatically be acknowledged. When OFF,
a connect request from a distant station will be answered with a <DM> packet, causing that
station to get a busy message from you. When this occurs, you will see a "connect request"
message on your terminal. See also: conmode, connect, intface, maxusers, monitor, nomode,
users.
• CONYers (immediate command)
This command w:ill place your KAM in the Convers mode on the current VO stream. See also: k,
command, stat.
• CPactime ON IOFF (OFF)
When OFF and in the Convers mode, packets are transmitted when the SENDPAC character
is entered, or when PACLEN is exceeded. When ON, packets are sent at periodic intervals
determined by PACTIME. See also: convers, cr, pac1en, pactime, sendpac, trans.

• CR ON IOFF {ON}
When ON the SENDPAC character (normally carriage return) is appended to packets sent in
Convers mode. When OFF, the SENDPAC character is not transmitted as part of the packet.
See also: lfadd, sendpac.
• CRAdd ON IOFF {OFF}
When ON, a carriage return will be added to every carriage return received from your terminal
before being transmitted in RTI'Y, ASCII, .AM:TOR,G-TOR, and Pactor. When OFF, no extra
carriage returns are added by the KAM Plus. See also: lfadd.
• CRSup ON IOFF {ON/OFF}
When ON, every other carriage return will be suppressed when two or more carriage returns
are received with no data between them. When OFF, no carriage return suppression occurs.
See also: auto If, lfsup.
• CStamp ON IOFF {OFF}
When ON, the daytime stamp is printed with all "*** CONNECTED TO" and
"*** DISCONNECTED" messages. When OFF, no daytime stamping of connects
and disconnects occurs. See also: connect, daytime, disconnect, mstamp.
• CText text (0 - 128characters)
This command sets a custom text message to be sent to any user who connects to your
MYCALL. To clear the CTEXT enter a single %character (CTEXT %). See also: cmsg, connect.
• CW en] (n =5 - 99) {20}
This command places the KAM Plus in the CW mode. If n is not specified, the speed set in
CWSPEED will be used for transmit and receive. Specifying n will allow you to enter the CW
mode at the desired speed. The KAM Plus will automatically adjust to copy stations within
approximately ±20 WPM from the speed selected. See also: canline, cwspeed, morse, pmode,
proslgn.
• CWAudio ONl OFF {ON}
When ON, the AFSK output of the KAM Plus HF port will provide morse code with an on/off
audio tone. This can be used for automatic CWID when operating ARQ modes CG-TOR, Pactor,
and .AM:TOR)or for sending morse code over an FM transceiver. You must also set the CWPTT
command ON for this to operate.
• CWBand n (n =10 - 1000) {200}
This sets the audio bandwidth for CW operation. A small bandwidth will improve reception
of CW signals, but will be more difficult to tune.
• CWFarnsw n (n =5 -99) {15}
This commands sets the character speed used when operating CW and the CWSPEED is less
than CWFARNSW. Characters will be sent at this speed, and additional time will be placed
between characters to lower the CW word rate to your selected speed.
• CWld [EVERY IAFTER] n (n=0 - 255) {EVERYO/EVERY O}
When operating packet, this command will cause a CWID to be transmitted periodically. When
set to EVERY, a CWID will be transmitted every n minutes. When set to AFTER, a CWID will
be transmitted ONCE after n minutes of no channel activity. See also: arqid, cwidtext.
