Expansion port output
Expansion port input
The extension port output is OC gate output. The user needs to connect the pull-up resistor and pull-up
level. The range of pull-up level is 0-50V and the sink current is 0-100mA. Exceeding the above
electrical range will damage the device interface.
The extension port input is the external trigger input terminal, and the falling edge is effective. The
interval between two falling edges should be greater than 100mS.
