Analog Inputs Flexible Acquisition Modes... Using The Input All DT9800 Series modules support 16 single-ended or pseudo- Channel-Gain List differential analog input channels or eight differential analog input channels. Software selectable gain settings of 1,2,4, and The DT9800 Series module can acquire data from one or 8 provide effective input ranges of ±1.25 V, ±2.5 V, ±5 V, and more analog input channels using an input channel-gain ±10 V. On the DT9801 and DT9801, you can specify a unipolar list. A 32-location channel-gain list allows great flexibility in range of 0 – 10V. configuring channels, sample rates, and gains. For example, it permits sampling non-sequential analog input channels, analog input channels with different gains, and digital inputs at the A/D sample rate.

All DT9800 Series modules feature 16 digital I/O lines. These Channels in an input channel-gain list are sampled in order lines are divided into the following 8-bit ports: Port A, input from the first entry to the last entry in the list. Channel and Port B, output. You can also read the status of Port A at numbering is zero-based; that is, the first entry in the input rates as high as the maximum speed of the A/D by including channel-gain list is entry 0, the second entry is entry 1, and so the digital input lines of Port A as a channel in the analog on. channel-gain list.
