11.2 Wiring
Connect your transducer to an AC/AC-LVDT Input channel by wiring it to the Input
Channel connector (the top connector on the instrument’s rear panel). 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 DAC Output and DAC Return pins are electrically isolated from all other pins on
the instrument.
