Chart Output	Two terminals (+,-) providing a 0 to 10 mV signal.This signal can be used to indicate the composition percentage of any one of the four eluents (%A, %B, %C, %D), the eluent flow rate (Flow), or the column temperature (Temp).
Pressure Output	Two terminals (+,-) for recording pump pressure traces. 10 mV/6000 psi analog output; bypasses microprocessor.
Inject	Receives a signal from an external injector (autosampler or manual injector) to initiate the chromatographic run. The Inject terminal also provides a signal to start a Waters 745B/746 Data Module (integrator). The Inject terminal accepts signals from several outputs, including TTL signals, open collector outputs, and contact closures.
