SETTING UP THE COBRA
-
note the Cobra must be connected to a receiver which is
bound to it’s transmitter. For power curve setting see overleaf.
Factory default values:
Bi
-
directional operation, Stop position at 1.50ms, Full fwd at
1.95ms, full reverse at 1.05ms, inertia control period 1 second, power curve 2.
Technical note: standard servo protocol is provided by r/c systems based on a pulse variation from 1 to 2 millisec-
onds, with the centre position therefore being at 1.5ms. In practice, with manufacturing tolerances and with
cheaper designs, this can vary significantly, which is why the calibration facility is provided on the Cobra. In some
cases, where the signal is a long way outside the specification, the Cobra may not be able to calibrate. If this hap-
pens, please contact us for advice.
1.
Turn your transmitter, then turn on your loco.
2.
The red LED will flash quickly for 2.5 seconds. Press and release set
-
up button to
enter calibration within this period.
3.
If there is no button press in this time, the Cobra will start normal operation.
4.
If the button has been pressed in this time, the LED will be fully ON.
5.
To alter
Inertia
, press and release the SET
-
UP button.
6.
The LED will now flash rapidly, press and hold down the button for the length of time
you wish the inertia to act for
-
up to a maximum of 31 secs. The LED will be fully on
in this time. If you do not wish to change the Inertia, just release the button within 1
second. Once the button is released you can power down the Cobra if you do not
wish to change any other settings, or proceed to setting the STOP, FULL FWD,
FULL REV and MAX SPEED settings.
7.
The LED will now flash slowly with equally spaced flashes. Put the stick or knob to
STOP (zero power) position and press and release the SET
-
UP button.
8.
The LED will now flash slowly with unequal flashes mostly ON. Put the stick or
knob in the direction you wish to be fully FORWARD (full power) and press and re
lease the SET
-
UP button.
9.
The LED will now flash slowly with unequal flashes mostly OFF. Put the stick or
knob fully REVERSE (full power) and press and release the SET
-
UP button.
10.
The Cobra can now be adjusted to reduce the Maximum Speed of the model. (If this
is NOT required, turn off the power and restart as usual.) You can now drive the
model with the speed control
-
WARNING the model will move
-
set the speed to the
desired maximum and press the set
-
up button once more, you will notice a decrease
in the speed of the model as the range is adjusted. Now power off and restart.
NOTES:
Unidirectional forward operation
-
if at step 7, the stick or knob is set to the lowest posi-
tion, and at step 8 and 9 is set to the same maximum position, the Cobra will operate in the
Forward direction only, within the set speed range.
Unidirectional reverse operation
-
if at step 7and 8, the stick or knob is set to the lowest
position, and at step 9 is set to the maximum position, the Cobra will operate in the Re-
verse direction only, within the set speed range.
Inability to calibrate
-
if at steps 7 or 8 the normal sequence is not achievable it may be
that the radio is providing an inaccurate PWM signal outside the range of the Cobra.
Please call us for advice.
