6300 Series ComboSource User’s Manual · Page 27
Arroyo Instruments has followed industry conventions for laser DB-9
connections, and is compatible with pin-outs from other vendors, such as ILX
and Newport. However, care should still be taken when interfacing the
ComboSource to other vendors’ products, and if you have any questions,
please contact your distributor or the factory.
Modulation Input
The modulation input BNC on the front 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 ComboSource 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.
TEC Output Connector
The TEC Output connection is a female DB-15, and has the following pin-out:
DB-15 Pin Description
1, 2, & 9 TE (+)

Using Remote Sensor
The remote sensor pins (pins 14 & 15) are used in RTD 4-wire mode, and
provide a remote measurement of the RTD voltage to eliminate voltage
measurement errors. See Working With RTDs below for more information. Do not
connect these pins to the TE+ or TE– pins, as damage may result.
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.
