DI–720/DI–722/DI–730 Series User ManualAccessories41The DI-205: Signal Input/Output PanelGeneralThe DI-205 is a termination panel for general purpose input and output. The DI-205 along with the supplied cableprovides a convenient way to interface digital input/output, analog output and analog input signals to DI-720 Seriesinstruments. Signal connection is via terminal strip for digital and analog output signals, or 5-way binding posts(banana jacks) for analog input signals.DI-205 Input/Output Panel InterconnectionsDigital Inputs (DI0 to DI7)The left end of the 20-connector screw terminal labeled “DGND” and “DI0” through “DI7” indicates the digital inputports of the DI-205.Digital Outputs (DO0 to DO7)The 8 digital output lines labeled “DO0” through “DO7” indicate the digital output ports of the DI-205.Analog Output (DAC1, DAC2, VOUT)The digital-to-analog converter (DAC) outputs have two applications: As a general purpose analog output accessiblethrough WIND AQ or Programmer’s SDK software or as a variable signal suppression voltage automatically enabledand multiplexed to all channels through Programmer’s SDK software.Input Signal ConfigurationEach DI-205 may be configured to connect to 16 single-ended or 8 differential channels. In addition, any combinationof single-ended or differential channels may be applied. A differential channel is configured by using two single-ended inputs according to the following illustration:-ODEL $) CHAN. 1 CHAN. 2 CHAN. 3 CHAN. 4 CHAN. 5 CHAN. 6 CHAN. 7 CHAN. 8S. GND S. GND S.
