4.8.3 The Operation in RS-232 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, you can send codes from the upper computer. In RS-232 mode, the laser emits on
conditions that the “Emission On” code (1B4F0D) is received, operation parameters are set and
remote modulation signal inputs from the “MODULATION” cable.
In RS-232 mode, 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 4.7.2Hyper Terminal
Setup. But you can’t set operation parameters from hyper terminal when the control mode is
RS-232.
4.9 AD Mode
AD mode is also remote control mode. In AD mode, the output power is set by analog
signal, and pulse mode is not available in this control mode.
