CAUTION

：

Please check the control voltage level and ensure that the level

is in accordance with the requirements. Over voltage and voltage ripple

may damage the product.

4.5 Control Modes

There are two different modes of operation-CW and modulation. In the CW mode, the laser

emits continuously, and you can set the output power by percentage of output power. In the

modulation mode, the laser emits in a waveform of pulses. The pulse can be set by upper

computer.

We provide three modes to control the product-hyper terminal, RS-232 and AD. The hyper

terminal mode is a local control mode; RS-232 and AD mode are remote control modes. In the

hyper terminal mode and RS-232 mode, you can set all the parameters in the CW or

modulation mode, but in the AD mode, the output power is controlled by input analog signal,

and the emission is controlled by input modulation signal.

We have sensors to monitor the operation conditions of the laser, if any abnormal condition

occurs, the laser will be stopped, and error information will be sent out from the RS-232 port.

4.6 Entering a Control Mode

The following diagram shows the process of entering a certain control mode.
