- AB/DR-3000 F RONT P ANEL -
There are several adjustments that can be made through the front panel of a AB/DR-3000. In addi-
tion the front panel displays various AB/DR-3000 conditions. Chief among these is the AB/DR-3000 heart-
beat. This is shown as the decimal point of the ÔselectÕ display. If this ever stops flashing, the hardware
deadman circuit on the AB/DR-3000 will reset both the Microcontroller and DSP within one second.
Each AB/DR-3000 has two status outputs. The state of these outputs is reflected onto the decimal
points of the other two displays. The #1 status output is shown on the left. The #2 status output is shown
on the right.
If the repeater is performing a countdown and the display isnÕt otherwise occupied, a spinning ÔoÕ will
be displayed. These will be on the left display if the left (or stereo) output is in delay, and on the right for
the right output. Start delays are shown by the ÔoÕ spinning in the upper half of the display. A delay be-
tween iterations when looping a single spiel will be shown by a clockwise spinning ÔoÕ in the lower portion
of the display. Delaying while doing a Ôloo-allÕ will spin the ÔoÕ in a counterclockwise direction.
F RONT P ANEL A DJUSTMENTS :
The front panel adjustments are made by pressing the ÔSELECTÕ button to choose the function you
wish to adjust. The selection is then incremented and decremented by using the up/down buttons.
Once an adjustment has been made, continue pressing the ÔSELECTÕ button to return the AB/DR-3000 to
its home position (the ÔselectÕ display blanked). These buttons have a one second delay before they start
repeating at ten counts per second. The ÔSELECTÕ button has an additional one second delay each time
it passes its home position. This makes it a bit easier to get back to home.
Any adjustment which can be made on the front panel will be indicated by the Ôcurrent valueÕ blink-
ing at the same rate as the ÔheartÕ decimal point on the ÔselectÕ display. If an adjustment is unavailable
(because you have selected a ÔfixedÕ level or another adjustment source), the Ôcurrent valueÕ will not be
blinking.
If the Configuration EEPROM is enabled for writing (see JP-7 below), any changes in the settings you
make will be saved. The next time the AB/DR-3000 is turned on, it will return to the levels you have set. If
writing to the EEPROM has been disabled, then the settings that can be adjusted will flash at a slower
rate than the ÔheartÕ decimal point. This indicates that any settings you change will only have an effect
until the repeater is turned off. The next time it is turned on, it will revert to the ÔdefaultÕ values for all of
the settings.
The Real Time Clock (RTC) on a repeater (if this option is installed) will be unaffected by the front
panel until you change any of the current settings. The ÔselectÕ display will then start flashing to indicate
that the new settings will be written to the RTC the moment the ÔselectÕ display is returned to its home po-
sition (display blanked). The seconds will be reset to zero and the clock will start keeping time.
The following adjustments are available:
