The laser is easily operated with a 0-10V DC control signal (corresponding to 0-100% laser power) through a 15-pin D-sub connector which provides a few other basic controls. There is also a static IP Ethernet interface, but unfortunately it is limited in its capabilities. The default IP address is 192.168.50.50 (which can be changed). By visiting http://192.168.50.50 and http://192.168.50.50/service.html an experienced operator can access status info, warning and error messages, and historical data in a web browser. Unfortunately, Synrad doesn't offer an easy way to pull data off of these pages and they just aren't useful for a typical user.
For anyone else working with this laser, I've posted the list of variable descriptions on Github. It was a fun challenge to extract this data and it was a great learning experience!
