6.3 Logic interface data
The pumps have a 15-way D-type logic interface connector located on the user interface
panel ( Figure: nXRi pumps , (6)). The logic interface connector can be plugged directly
into the 200 W Turbo Instrument Controller (TIC) with an nXRi TIC cable and in
conjunction with controller extension cables.
For Turbo controller, or Turbo and Active Gauge controller (TAG), a suitable connector
mating half must be used (not supplied) to connect the nXRi pump to the customer
control system. Refer to and Table: Logic interface pins for the electrical connections.
