Check your device’s calibration certicate and user manual for the actual electrical input/
output requirements, as all instruments are custom congured to some extent.
NOTE: Pins 1, 9, and 10 are connected together inside of the device and are common
grounding points.
N/C = Not Connected/Open (can be used for custom pin assignments – please consult factory)
* Added to allow for full use of features on FMA-1600A devices, may not be present on host wiring.
The following pin-out chart describes the safest and generally compatible arrangement
when connecting a non-FMA-1600A Series DB15 wire to a DB15O equipped FMA-1600A
Series. Not all features may be available between brands, but the common denominators are
featured in our DB15 offerings, along with some options for customization.
DB15 Pin-Outs
If your instrument was ordered with a DB15 connection, be sure to check the
Calibration Label on the device and reference the appropriate pin-out diagram.
