1.Remove the Recorder’s case top.
2.There is a predrilled hole to accommodate an external altitude tube. Look at the back of your recorder cover, and use an x- acto knife to carefully cut the label around the hole.
3.You can now install an external altimeter tube to the nipple of the altimeter sensor just like you do the pitot tube for airspeed, using an extra piece of rubber pitot tube, or similar. Choose either option A, B, or C for the static source, as described in the Airspeed section above. If you have installed a static airspeed tube already, that same static tube can be shared with the altitude static source, by using an optional ‘T’ fitting, as shown in Figure 1.
Powering the Glide Recorder
IMPORTANT: If you are using the 1 Watt 900 MHz Transmitter, special care must be given to ensure that the
supplied power remains between 5V and 5.75V. The 1 Watt Transmitter will stop transmitting if powered above 5.75V, and will reduce power output to 500 mW (when in High Power mode) if the voltage drops below 5V.
The battery harness is the cable with a Futaba style male connector on one end, and male universal servo connector on the other end. To power the system, plug the Futaba end into any one of the recorder’s servo slots. The universal male end of the harness can plug into a spare channel of your
receiver, or you can connect a separate battery to the unit. The battery must be at least 4.5 volts to power the recorder.
Installing the Seagull Transmitter in your Model
Choose a location in your model to install the transmitter. The transmitter is normally mounted with Velcro or double sided tape. Ideally, the transmitter will be installed with its antenna and body as far away from your radio receiver (RX) as possible, with the antenna protruding at right angles with your RX antenna, to reduce the possibility of interference. For example, if you have a model plane with the receiver mounted horizontally along the plane’s fuselage, mount the Seagull so that the antenna is protruding from the model vertically, as far forward of the RX antenna as possible. Best reception will be obtained if the Seagull antenna is vertical.
Connecting the Seagull Transmitter to your Data Recorder
Ensure that the Recorder is not powered when connecting the transmitter, and ensure that the red wire of the transmitter
cable corresponds with the red dot on the port label (to the right of the connector). Plug the Seagull Transmitter cable into the “Expansion” port on your Recorder, as shown in Figure 1. Install the transmitter in the upper row of pins, as shown in the figure.
Using the Seagull Wireless Dashboard
The Seagull Dashboard Receiver (the Dashboard) operates from a standard 9V battery. The battery installs in the back
Approximately
Note: If the Dashboard will be unused for long periods, it is a good idea to remove the battery.
Note: When removing the battery clip, use your thumb to pop the clip off from the side without the wires. Pushing on the wire side can break the battery clip or the wires.
Variometer Function: Your Dashboard contains a sophisticated Variometer, employing electronic Total Energy Compensation, based on changes in Airspeed. Basic variometers do not support total energy, which means that “stick thermals” are reported by the variometer if you descend or ascend due to elevator movement. Standard total energy variometers reduce the effects of moving the
