Arroyo Instruments has followed industry conventions for laser DB-9
connections, and is likely compatible with pin-outs from other vendors.
Modulation Input
The modulation input BNC on the rear panel accepts a 0V to 10V input signal for
analog set point control of the driver. The modulation input is optically isolated
from the rest of the control circuits in the 4200-DR and electrically isolated from
ground, so you should not need to be concerned about ground interference
from any modulation source. The center pin is positive and the outer shell is
ground.
USB Connector
The USB connector is a standard Type B female connector, and can be plugged
into any USB 1.1 or USB 2.0 port. For more information on using the USB
interface, see the Computer Interfacing Manual which is included on the CD
that accompanied this product.
