Frequency Offset OPTION
To adjust the frequency use the
BAND
up and down to make the “OFF” flash. Then press
the
SELECT
button to enter the menu and use the BAND up or down button to adjust your
fre/- 15. Which is essen/-1.5% of the frequency that the controller is operaing
on.
This is basically a calibration function that can be used to compensate for frequency shift
caused by ice buildup or rain (usually makes the antenna look to long), both of which can
occur for long enough periods to be irritating. It can also be useful in some cases of interac-
tion or low antenna height situations. There will be a number in the range of +/- 15 displayed
in the upper right of the LCD display indicating the offset value. This is a global adjustment to
all bands and is based on a percent of frequency. The number is for reference only and does
not scale directly. When making this adjustment it is possible to move off the best perform-
ance point so some experimenting may be necessary. Adjustment using this feature affects
all frequencies proportionately. True for all options, the changes made in this menu will be
saved when the controller power is switched off or after about 3 minutes the controller will do
an automatic save.
Remote Driver Board OPTION
To activate the “DRIV” (which is the remote driver board option) option use the
BAND
up and
down to make the “DRIV” flash. Then press the
SELECT
button to enter the menu and
select “YES” to enable the remote driver option.
CONTROLLER OPTION
There are many different options and configurations for the SDA 100 controller. Each option
allows the user more flexibility, whether its better protecting the controller from lightning or
from operator error. Each option will require the user to know how to set up and activate
each individual option in the controller.
TRANCEIVER INTERFACE
This option is used to link a radio, computer or another SteppIR controller to the SteppIR SDA
100 controller. This option is physically located on the back of the controller with two 9 pin
Dsub connector in the “Data In / Radio” and “Data Out” plugs. Refer to
Figures 3 - Figure 6
for wiring configurations with the Transceiver Interface.
