3. Control Interface
There are DB9 and DB25 interfaces at the rear of the laser. The DB9 is a RS232 interface
only used for debugging, no needs to connect. And DB25 is the joint interface connecting control
system with laser system, please make sure the connection is reliable before operation. Feet of
the DB25 are defined as follows in Fig. 5.
