accessories after all accessories on the External bus daisy chain are configured
with a unique address.
Bus through output port
Connects additional accessories to the External bus in a daisy chain
configuration. A bus defeater must be connected to this port if no other
accessories are used with the SuperK laser. Without a bus defeater at the end of
the accessory External bus daisy chain, the interlock loop circuit will be open and
emission disabled at the SuperK laser.
SuperK VARIA Control
Software
Description
Both the SuperK laser and the VARIA accessory are controlled using NKT Photonic’s
CONTROL management software installed on a PC or the front panel interface.
A management PC with CONTROL installed on it can connect to the laser using either
the USB serial port or the 10/100 BASE-T Ethernet port on the laser. CONTROL
communicates with the VARIA through the laser’s External bus connection.
Chapter
“CONTROL Interface”
contains information on using NKTP’s CONTROL
software and how to connect to and control the VARIA. It also includes instructions on
how to set the center wavelength to a resolution of 0.1 nm to match the intended
application.
CONTROL software installation
Refer to the procedure found in
Appendix C
.
Status LEDs
The VARIA includes three status LEDs as described in
Table 1
. The LEDs are
located on a side panel next to the External bus ports as shown in
Figure 6
.
The emission LED is lit ON RED when the connected SuperK laser’s emission is
enabled. When ON RED, laser light is present at the primary and auxiliary optical
output ports.
Warning: If any of the VARIA aperture shutters are closed, emission is blocked. The
position of the shutters does not affect the status of the emission LED, only the emis -
sion status of the connected SuperK laser.
