Provide a specific implementation process in actual applications below:

1, equipment connection

Multiple-channel output fire control plate of the present invention is connected in unmanned plane work high above the ground system.The remote signal line (in vain red-black three looks) of selector is inserted any one idle channel of unmanned plane receiver; On unmanned plane eight piece rocket electronic fuse is plugged into eight double loopers of multiple-channel output fire control plate; By the independence single looper of rocket firing electric power connecting to multiple-channel output fire control plate.Notice that looper is just lower negative, as used standard Du Pont plug, fire control plate has inverse inserting-preventing to design.

2, remote controller prepares

Opening the emitter of unmanned controller, is channel allocation one control (knob and switch) of grafting multiple-channel output fire control plate.The stroke up and down of this passage is all adjusted to 100 of acquiescence.

3, remote-control channel stroke is arranged

Keep the unlatching of remote controller transmitter, then power on to unmanned plane receiver.The red LED indicator lamp of multiple-channel output fire control plate starts fast blink 3 second, is that remote-control channel stroke arranges window during this.If never set passage stroke before, within this 3 second, please rotate back and forth the knob of MUX grafting passage, or the switch one to twice of this passage that fiddles with.Confirm that the range of both direction got to all by knob and switch.Now the red LED indicator lamp of MUX becomes double frequency flicker, and prompting has been remembered current remote-control channel stroke and arranged.

Only have first use this unmanned plane multiple-channel output fire control plate or changed remote control equipment or changed passage of plugging into, being just necessary that carrying out this remote-control channel stroke is arranged.Multiple-channel output fire control plate has memory function, and under other normal service conditions, if not turning knob (or toggle switch) in 3 seconds window phases after the power-up, what fire control plate can load last time automatically arranges numerical value.

Arranged if multiple-channel output fire control plate never carries out remote-control channel stroke, or load the setting value failure of last time, then red LED indicator lamp can glimmer continuously and healthily, arranges until rotation path knob (or toggle switch) completes remote-control channel stroke.
