                         N8062A  Navigation Simulator Effect and Installation

Description of Lighting Effects

This simulator is programmed to run dual red LED beacons (vary in intensities to simulate  rotational effect), and 1 red LED configured as port or left-side wingtip strobe, and 1 green LED for starboard, or right-side wingtip strobe. Timing of the beacons are simultaneous and approximately once per second. After every second beacon cycle the strobes pulse for a short 25ms burst. This mimics many tail beacons and wingtip strobes seen on many aircraft.

Connecting the N8062A

Installing the N8062A is very straightforward. Its tiny size and thin construction will allow it to be placed nearly anywhere in any scale model. Because the module has circuitry on both sides, care must be taken to be sure that the components or wires soldered will not make contact with any metal object causing a short circuit.

The N8062A can be powered by battery or any well-filtered and regulated DC power source with an output of 6-18VDC.

Included with the module are two 6� lengths of #32 insulated wire. If necessary, these can be used for power input wires.

Solder point #1 is the + DC power connection as shown in Fig. 1.


                              Figure 1

Important note: A low-wattage iron with a pointed tip should be used for connection of wires. Too much heat or solder can easily damage the wires or module and void the warranty.

Also, all connecting wires should be pre-tinned before soldering them to the module. This will make connection quick and easy and ensure excessive heat is not applied to the solder points.

 Solder point #2 is the -DC (or ground) power connection.


Connecting LEDs

Included with this module are 3 small packs of 1/8-watt surface-mount resistors. Upon close examination of the resistors (viewing them through the clear film covering on each pack), note each resistor has a series of number or number and letters printed on them. These correspond to the resistance value in ohms, of the resistors:

60R4 = 61 ohms

1500 = 150 ohms

1001 = 1000 or 1K ohms

When connecting the LEDs, proper polarity must be observed. LEDs are �polarity sensitive� and will not function if connected backwards. The N8062A is configured to allow connection of two 20 ma red LEDs, wired in series with device voltages of 1.75-2.0 volts DC (Ngineering�s Micro and Nano red LEDs, as well as many red LEDs available). These LEDs will use the on-board current limiting resistor so they can be wired directly. See Fig. 2 below.

Using wire appropriate for the size of the LEDs and their placement in the model, connect the two red LEDs in series with each other (daisy-chained anode to cathode) to the simulator module as shown below. Connect the cathode wire (the � connection) of the first LED to point 3 on the module and connect the anode wire of the second LED (the +) to solder point 4.

                                                                            Figure 2 


Note: If only one red beacon is desired instead of two, connect one of the supplied61-ohm resistors in series with the one red beacon LED to be wired. This resistor will balance the current load as a substitute for the second LED. See Fig. 3 below for details.

The next two (2) LED connections will be for the wingtip strobe lights. Each LED must be wired with an external resistor in series to limit the current flow through the LED. These two LEDs are different in color and have different device voltages. The red LED has a device voltage of 1.75-2.0 volts DC (Ngineering�s Micro and Nano red LEDs, as well as many red LEDs available). The green LED is a high-intensity Signal Green LED witha device voltage of 3.3-volts DC (such as Ngineering's Nano Signal Green). As a result, each must use a different valued resistor. Included with this module are two additional 1/8-watt surface-mount resistors (we�ve included a spare with each). These resistors are tiny for easy placement and have pre-tinned tabs so soldering is easy. The green LED�s cathode is to be wired to solder point 5 on the module. Select a 1K-ohm resistor and wire it in series between this LED�s anode and point 6. The red LED's cathode is to be wired to solder point 7 on the module. Select a 150-ohm resistor and wire it in series between this LED�s anode and point 6. See Fig. 2 or 3 for details of these connections

 Once again, be sure to use a low-wattage soldering iron when connecting wires to the module. Our N40M2 12-watt Iron with either the N408I (iron clad) Needle Tip, or the N408X (bare copper) Needle Tip would be an excellent choice for this operation.

This completes connection of the N8062A module. It is recommended that a thorough re-inspection of all connections and module placement be performed prior to applying power to your model. We hope you enjoy the added realism our module provides.
