Enabling Voice ID Operation.
To allow automatic voice id to
occur, the Voice ID option must be
enabled on the COR-5 control board,
either by sending the appropriate dtmf
command (usually "302*") or by
having that option default on by
eprom programming.
Playback by DTMF Request.
Any repeater user can request
message playback by sending the
Playback Voice Msg command,
usually "003*". You can use the
command for testing, as well. You
can make prerecorded messages
available for call up by club members,
for instance.
AUXILIARY RECEIVER.
The controller board has
provisions to connect an auxiliary
receiver, which can be used simply as
a control receiver to allow touch tone
commands to be applied to the
controller on an alternate frequency,
perhaps on another band.
The aux. receiver can also be used
as a second input for the repeater
itself, either as a link from another
receive site or to link two repeaters
together. In such a case, the receiver
remains simply a control receiver,
always having access to the touch
tone decoder, unless the auxiliary
receiver ON command is sent, at
which time the receiver is connected
to the main repeater audio and COS
circuits. The aux. receiver will then
perform generally the same as the
main receiver, except that touch tones
are not muted on the transmitter as
they are when received on the main
receiver.
To disable the repeater audio and
COS link with the aux. receiver, send
the auxiliary receiver OFF command.
Then, the aux. receiver reverts to
being simply a control receiver, having
access to the touch tone decoder in
the controller but not the transmitter.
ALARM FEATURE.
There are provisions to connect an
external alarm circuit to the repeater.
(See Installation and Maintenance
Manual for details.) This allows an
external circuit to sound an alarm on
the air if activated. The alarm
function might be used to indicate a
break in at the building or cabinet
where the repeater is located.
Another use might be to indicate
when battery power is low in a solar
powered installation. And some
repeater owners connect the alarm
circuit to a weather radio so the alarm
is heard on the air if the NWS has
issued a severe weather warning.
If tripped in this way and the
alarm is turned on, a wailing sound
will be transmitted for about ten
seconds. Thereafter, the courtesy
beep is changed to a short wailing
sound until the alarm circuit is reset
by touch tone command.
To activate the alarm feature, you
must send the owner enable
command (password) followed by the
alarm ON command. To disable the
alarm completely, use the alarm OFF
command. If the alarm has been
tripped, you can restore the normal
courtesy beep with the alarm RESET
command. If you want to be sure the
alarm is definitely set, you can use the
alarm TEST command to trip it
remotely. All these commands require
the owner password.
It is recommended that you not be
tempted to reveal your owner
password to someone just to let them
reset the alarm in case it is tripped.
There is no harm done in leaving the
courtesy beep in the alarm condition
until you have a chance to discover
that the alarm has been tripped and
reset it yourself.
The alarm circuit has a memory of
sorts. Once the alarm has sounded, it
will not sound again until after it is re-
set. However, if the alarm is tripped
more than once, it will sound again
immediately after you reset it. If this
occurs, simply reset it again. The
second reset will restore the normal
courtesy beep, indicating that the
alarm is indeed reset.
If the alarm continues to sound
after reset the second time, it means
that the alarm circuit is constantly
tripped, i.e., a constant ground is
applied to the alarm input. The
condition causing the alarm was not
just a temporary event. In such a
case, you can either leave it tripped
until the condition is cleared or you
can turn off the alarm altogether with
the alarm off command.
ADJUSTING PARAMETERS.
General.
The following five functions allow
you to change cor/cwid parameters by
touch tone command, providing that
you have sent the owner password.
Changes to these parameters are
saved for as long as power remains
applied to the RAM memory in the
repeater.
If power to the memory is inter-
rupted or if you send the reboot
microprocessor (reset-to-defaults)
command, these parameters will be
reset to the default values
programmed into the EPROM at the
factory from your Questionnaire.
To adjust a setting, send the
appropriate command, which consists
of three digits to identify the
parameter to be changed, and a
fourth digit, either "*" or "#", to make a
parameter slower/faster, lower/high-
er, longer/shorter, etc. Settings are
made in steps; so to increment more
than one step, it is necessary to send
the command as many times as is
necessary to reach the setting you
want. For instance, if your present
Courtesy Beep Type is "3" and you
want to use type "5", send the
command to "go higher" twice, i.e.,
once to go to "4" and again to go to
"5".
There are predetermined limits to
how much you can change each
parameter. You can't harm anything
by asking for a change beyond a limit;
the computer simply refuses to
change beyond limits. If you request
a change and the present setting is
already at a limit, the computer sends
a long series of dits as a warning that
you can't go any further in the
requested direction. You may then
opt either to keep the present setting
or try changing in the opposite
direction.
Note that CWID interval and
transmit time-out period are fixed
constants which are burned into the
EPROM from settings you selected on
your Questionnaire. They are not
changeable.
Cw Speed.
Use the cw speed - slower/faster
pair of commands to adjust the speed
of the station id and cw status
messages. The speed is adjustable
over a range of 5 to 22 words per
minute in small increments. Each
time you make a change, it will be
evident in the "R" roger acknowl-
edgment of the next command you
send.
You can also try it out by forcing
the cwid with the test cw command;
however, since the owner command
(password) is disabled whenever the
cwid runs, you will need to re-send
the owner command enable password
again before you can make further
changes requiring the password.
