Connections of the airsoft micro switch Plug in the airsoft micro switch here. Note the exposed metal of the plug is to face the relay box (colour may vary) Plugging into any other pins could cause damage to the IBU3 check and double check! Note feature only available from Firmware v0.12 onwards
Connections of the Taigen airsoft & recoil unit Taigen recoil connector The IBU3 module allows to drive the new Taigen recoil units for airsoft tanks without changes. Connect the power cable (male) to the female connector as shown. Make sure the red wire plugs into the positive side (closest to the HL turret socket) Note The Taigen recoil system can be damaged with incorrect polarity it is your responsibility to check before you have connected it correctly. The Taigen recoil system does NOT support batteries 7.4v and above Connect the signal cable (female) to the connector male as shown. If the recoil is constantly working you need to swap the 2 wires around. DO NOT turn the plug around this will cause a short on the adjacent expansion socket pins. Note feature only available from Firmware v0.12 onwards
Selecting airsoft mode. On the Misc Setup page, tick the Airsoft box to enable Airsoft Mode. Note The airsoft micro switch needs plugging into the IBU3 as detailed above or it will not activate the sound and track recoil if activated.
