lasing at power on for special OEM integration. This configuration is password
protected and this password mustn’t be shared with people who are not trained
on the laser safety issues associated with Class IV laser emission. Contact us to
get this password.
•Low alarms : the module starts with no laser emission, current level is 0
mA, alarms are set at low levels (100 mA average, 500mA peak current)
•Zero current : the module starts with no laser emission, current level is 0
mA, Alarms are set at the same current levels as previously saved by user.
•Previous (default mode) : the module starts with no laser emission,
current level and Alarms levels are the same as previously set and saved
by the user.
•Previous OEM : the module starts in exactly the same configuration as it
has been previously set and saved by user. If laser was on, the laser is on
when the power supply is applied.
oSave
Click on this menu item to save the current operating parameters into the CCS-I
internal memory. These parameters will be saved as default parameters in the
flash memory and will be retrieved by the CCS-I module at the next power on (even
