Hi,

This is an extract from some notes I wrote a while back on Configuring a
KAM 9612 Plus TNC to operate as a APRS DIGI or for use with Xrouter / BPQ
systems. The full document (PDF) can be found in the Downloads section of
the Gloucestershire Repeater Group web site at http://www.grg.org.uk

System Configuration

Note: After clearing any previous configuration using the PCB Jumper (J3)  
or using the TNC's "restore default" command the KPC 9612 defaults to
auto-detection of serial port baud rate, and expects to see a series of
"*" characters sent at the desired speed, after which you must set a
callsign.

The "abaud" command can be used to change the serial baud rate to one of 
the other standard baud rates (300,600,1200,2400,4800,9600,19200,38400) if 
desired.

TNC APRS Digi-repeater

The parameters below will provide a basic configuration for an APRS 
Digi-repeater (as used at MB7US / MB7UC):

	mycall <system_call>
	int terminal
	reset

Note: The above commands are usually required before the KPC will let you
use some of the more advanced features. Allow the TNC to restart, then:

	pbbs 0
	conok n/n
	myremote <remote_call>
	rtext <remote_password>
	mygate %
	myalias %
	mypbbs %
	mypage %
	mynode %
	txdelay 25
	cwidtext <mycall>
	cwid e 30
	cd software/internal
	blt 1 e 00:30:00 start 00:00:00
	blt 2 e 00:30:00 start 00:15:00
	ltp 1 aprs v trace3-3
	ltp 2 aprs v trace7-7
	lt 1 !<Latitude></><Longitude><#><Descriptive_Text>{KPC9612}
	lt 2 )<ItemID>!<Latitude></><Longitude><#><Descriptive_Text>
	uidigi on relay,trace,wide
	uidwait on
	dwait 0
	slottime 10
	persist 63
	uiflood wide,30,noid
	uitrace trace,30
	xmitok y/n
	daystr dd/mm/yy hh:mm:ss
	hid off
	mon off
	daytime <YYMMDDHHMM>

where:

<YYMMDDHHMM> Format for the date and time: 2 Digits for each of Year,
Month, Day, Hour, Minute. (It may accept 2 extra digits for Seconds).

<system_call> Callsign & SSID for the system (i.e. MB7UC-0).

<remote_call> Callsign & SSID for remote control interface. (i.e.  
MB7UC-8)

<remote_password> String of random characters, which form a 'secret'
password, which is required when anyone connects to the 'myremote'
callsign, which will permit remote control of the system parameters. To
use this you will need to create yourself a little lookup table like the
following to make it easy to answer the password prompt:

		0   1   2   3   4   5   6   7   8   9
	00	N/A
	10
	20
	30
	40
	50

<Latitude> The latitude value for the 'object' location give as 2 Digits
for Degrees, 2 digits for Minutes, a decimal point and 2 digits for
fractions of a minute, followed by a "N" for North or a "S" for South.

<Longitude> The longitude value for the 'object' location give as 3 Digits
for Degrees, 2 digits for Minutes, a decimal point and 2 digits for
fractions of a minute, followed by a "W" for West or a "E" for East.

</>	The first character used to define the 'object' Icon.

<#> The second character used to define the 'object' Icon.

(For further information see APRS specification).

Up to 4 strings can be entered for the "LT x" commands, each of these can
be used to generate beacon messages for an object / item using matching
"BLT x" and "LTP x" commands (See APRS Specification and KPC Manual).

{KPC9612} Optional system version information (See APRS Specification).

<ItemID> Item ID as per APRS Specification (3 to 9 Characters).
 

KISS mode configuration.

The parameters below will provide a configuration suitable for KISS
operation:

	mycall <call>
	int terminal
	reset

Note: The above commands are usually required before the KPC will let you
use some of the more advanced features. Allow the TNC to restart then
enable the cwid:

	cwidtext <mycall>
	cwid e 30

Enable software DCD on the 1200 bund port:

	cd software/internal

Enable transmission on both ports:

	xmitok y/y

Set the KISS address for the 2 radio ports:

mydrop <m>/<n>

	<m> = id for 1200 port
	<n> = id for 9600 port
	(Range 0 to 15)

Set KISS Polled / Checksum options (if required by software):

	xkpolled on
	xkchksum on

Enable KISS mode:

	int xkiss		Enables extended (multi-drop) KISS.
	or
	int kiss		Enables plain KISS
