4.9.2 The Operation in AD Mode
Before you start the laser, check the wiring, cooling connection and the most important, the
delivery cable and optic output terminal are OK. Make sure that the interlock is shorted, and the
laser emission button is up (emission disabled). Then start the chiller.
Turn the key to “REM” position to start the laser, and system start self-check. If the
interlock is not shorted or the “LASER” button is pressed down, the system self-check cannot
pass. In this condition, you must power off the laser, and deal with the problem, then start the
laser again.
The system self-checks will pass in about 30 seconds, then “RDY” signal will be sent. After
that, the laser is ready to receive analog signal, and you can press down “LASER” button to
enable the laser emission.
In AD mode, the laser emits on conditions that “LASER” button is pressed down or
“LAS_C” is high, analog signal is received and remote modulation signal inputs from the
“MODULATION” cable.
You can still use hyper terminal to monitor the status of the laser. All you have to do is to
connect the “RS-232” cable to your PC, then start windows hyper terminal, and configure it as
stated in 4.7.2Hyper Terminal Setup. But you can’t set operation parameters from hyper terminal
when the control mode is AD.
CAUTION
：
Please ensure that the analog signal DO NOT exceed 10V.
