Quick Start Guide 

3.1  Hardware Set Up 

 

For first use, plug the main power cable into the back panel connector, and then plug the other end into an AC wall 
receptacle. Flip the power switch on the back panel to the ON (I) position. The unit will 

now be in the “Standby” mode, 

and the front panel standby button should glow amber.

Attach the polarization-maintaining (PM) loopback fiber optic cable between the Laser Out and Laser In PC/FC connectors on 
the front panel. Be sure to clean both ends of the fiber as described in the Maintenance Section of this manual. For the MX10C 
series: attach the SMA loopback RF cable between the  Amplifier RF Out

 

and Modulator RF In SMA connectors on the front 

panel. (This instruction does not apply to transmitters in the MX40C series, as these do not have an Amplifier RF Out port.)

MX10C series. This cable is not installed on the 

MX40C series.  

Insert the key into the interlock switch and turn it towards the unlock symbol (

). This allows the laser to be turned on, but the 

LASER  ON  indicator  will  not  glow  green  until  the  laser  is  actually  turned  on  by  the  touchscreen  button.  Turn  on  the  unit  by 
pressing the amber standby button on the front panel which will then turn green to indicate the unit is fully on. The touchscreen 
display will come up with a boot screen for about 5 seconds and then go to the home page. The unit will initialize in the factory 
default state with all functions OFF.
