1.1. Installing the Mercury SRS in the model
The Mercury SRS must be screwed to a hard surface in the model, otherwise it is
possible that the integral iGyro will not work properly. If the mounting plate is large, it
must be stiffened by the addition of cross-struts. Please note that the Mercury SRS
must always be installed in the model at right-angles to the fuselage centreline. The
actual orientation of the Mercury SRS is unimportant: it can be installed in any location
which is at 90° to the direction of ight. The actual installed position is automatically
detected later when the Assistant is invoked.
The switch is mounted on the fuselage side. As is usual, the inside of the switch
opening should be stiffened by adding a hardwood doubler to prevent serious vibra-
tion from reaching the switch; this is particularly important if the fuselage is made of
GRP. In the case of scale models it is often undesirable to have an exposed switch
on the outside, and for such applications we offer the MagSensor or the Magic Jeti
Switch (only Jeti TX) as alternative methods of switching. Please note, however: the
SensorSwitch is essential for programming the unit, and should always be accessible.
The OLED screen can be installed in any location where it is clearly visible. If the stan-
dard cable (50 cm) is not long enough, we can supply extension leads.
1.2. Connections
The rst step in operating the PowerBox is to connect two batteries to it; the two
packs should be of the same type and capacity. Connect the switch, the screen, both
receivers (Spektrum system: four satellites) and the optional GPS II sensor using the
patch-leads supplied in the set. The batteries can be either 2S LiPo, 2S LiIon, 2S LiFePo
or 5S NiMH types. We recommend the use of PowerPaks, which include integral elec-
tronic charge circuitry. If you intend to make up your own battery packs, please note
that correct polarity is vital, as the unit does not include reverse polarity protection in
order to avoid power losses.
Connecting a battery with reversed polarity - no matter how briey - will instantly
destroy the voltage regulators in the PowerBox.
