Figure 14: Wiring in AD Mode
The wiring in AD mode is shown in Figure 14. There is an important difference in the
„CONTROL‟ cable connection - 24V must be applied between „AD/RS‟ and „EGND‟. If you
don‟t use remote emission control, left „LAS_C‟ disconnected. The „MODULATION‟ and
„INTERLOCK‟ cable connection are same as wiring in hyper terminal and RS-232 mode. If you
want to monitor the system status in hyper terminal, you can still connect the „RS-232‟ cable to
PC. The analog signal is input from „AD‟ cable.
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-check 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 4.7.2 Hyper Terminal Setup. But you can‟t set operation parameters from hyper
terminal when the control mode is AD.
