10.2 Wiring
Connect the transducer to a Strain-Gage Input channel by wiring it to the 12-pin connector of that channel. The Customer Information Sheet that shipped with the instrument describes which cards are installed in each channel. The pin-out for this
connector is shown on the following table.

The Analog Output and Analog Return pins are electrically isolated from all other pins
on the instrument.
The maximum recommended cable length to a Signature Module is 100 feet [30m].
NOTICE
If you are not using remote sensing of excitation, jumper (+)Sense to (+)Excitation and (-)Sense to (-)Excitation. If nothing is connected to (+)Sense and ()Sense, the instrument will enter the ERROR mode with error code 46.
