coincident with the 'ALARM' indicator; you can use it as a remote fault indication. You can still
use window hyper terminal to monitor the laser, in this condition, you must connect 'RS-232' to
your computer.
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 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, 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, analog signal is
received and remote modulation signal inputs from 'MOD'.
You can still use hyper terminal to monitor the status of the laser. All you have to do is to 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.
4.10 Red Guide Laser
The red guide laser is integrated in the laser source, and the red laser is 0.5mW~1mW.
When you start the laser (use the key switch or remote switch, refer to 4.4.1) the red guide laser
will emit if 'LASER' on the front panel is up and 'Emission On' command is not sent to laser
through the RS-232 port (If you use RS-232 mode). Press down 'LASER' on the front panel or
send 'Emission On' command to the laser, the red guide laser will be off.
CAUTION：Please ensure that the analog signal DOES NOT exceed 10V,
or product may be damaged.
