Input port of foot switch. The connection method is: when the

pedal is stepped down, the low-level signal will be inputted to

this port; when the pedal is released, the port will be

disconnected or the high-level signal can be inputted to this

port; when the stepped-down pedal is held for not less than

100 ms, if the machine lies idle, it can be started for work; if

the machine is in the working state, the work will be

suspended; of the machine is in the suspension, the work will

be restarted, that is to say, the function of the pedal switch is

the same as that of the “Start/Pause” key. If the interval time to

the first stepping-down of the pedal should be less than

100ms when the pedal is stepped down once again, the

second stepping-down of the pedal will be considered invalid

by the mainboard.

Input from protective port. If the machine needs to be

protected in the special state (such as door open protection),

the protective signal can be inputted from this pin. This pin can

be enabled and prohibited. This signal is not inquired by the

mainboard if this pin is prohibited; if this pin is enabled, when

the input is high-leveled or this input port is suspended, the

machine will be protected, the work suspended and the laser

closed.

Input for manual laser on/off. Low level is to open laser and

high level or no-connection is to close laser.

Stop key input, used to stop the running work(Low level valid)
