Status LED The Status LED indicates the communication status of the USB-3103. It flashes when data is being transferred, and is off when the USB-3103 is not communicating. This LED uses up to 10 mA of current and cannot be disabled. -
Page 10: Screw Terminal Banks
Screw terminal banks The USB-3103 has two rows of screw terminals—one row on the top edge of the housing, and one row on the bottom edge. Each row has 28 connections. Use 16 AWG to 30 AWG wire gauge when making screw terminal connections. -

DIO5 54 DIO CTL DIO6 55 DGND DIO7 56 +5V Figure 5. USB-3103 signal pinout Analog voltage output terminals (VOUT0 to VOUT7) The screw terminal pins labeled VOUT0 VOUT7 are voltage output terminals (see Figure 5). The voltage output range for each channel is software-programmable for either bipolar or unipolar. The bipolar range is ±10 V, and the unipolar range is 0 to 10 V. -

100 Hz/#ch max, system dependent Note 1: The USB-3103 output voltage level defaults to 0 V whenever the output voltage range is reconfigured. The USB-3103 output voltage level will also default to 0 V: 1) Whenever the host PC is reset, shut down or suspended. -
Page 15: Analog Output Calibration
The maximum differential non-linearity specification applies to the entire 0 to 70 °C temperature range of the USB-3103. This specification also accounts for the maximum errors due to the software calibration algorithm (in Calibrated mode only) and the DAC8554 digital to analog converter non-linearities. -
