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, 3, 9, 10, and 14 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).
The following pin-out chart describes the safest and generally compatible arrangement when
connecting a non-FMA-1600A DB15 wire to a DB15 equipped FMA-1600A. Not all features
may be available between brands, but the common denominators are featured in our DB15
offerings, along with some options for customization.
