Connecting the N8061/A Early-era Machine Gun Simulators


Installing the N8061 or the N8061A 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.

These Simulator 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 an LED to the N8061 & N8061A

When connecting the LED, proper polarity must be observed. LEDs are “polarity sensitive” and will not function if connected backwards. The N8061 is configured for the connection of one 20ma yellow LED with device voltage of 2.0-volts DC. This covers all of Ngineering’s Micro and Nano yellow LEDs, as well as many of the yellow LEDs available. The N8061 has on-board current limiting resistance to protect these LEDs so no external resistor is required.

Using wire appropriate for the size of the LED and its placement in the modeling project, connect the LED cathode (the – connection) to point 3 on the module and its anode (the +) to solder point 4. If wiring the N8061A, connect a second LED with its cathode wired to point 6 and its anode to solder point 4. See Fig. 2 below for a schematic layout of LED hookup.

Solder point 5 is for gun control (firing), and can be connected to any switch (momentary pushbutton or magnetic reed switch) which is then tied to -DC (ground).

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 N8061 & N8061A modules. 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.
