Signal Connections
This chapter describes the signal connections to the SC-2040 board, and cable wiring.
I/O Connector Pin Description
Warning: Connections that exceed any of the maximum ratings of input or output signals on
the MIO-16 can result in damage to the MIO-16 board and to the personal
computer. This includes connecting any power signals to ground and vice versa.
National Instruments is not liable for any damages resulting from any such signal
connections.
Corresponding signals on connectors J11 and J12 are connected together through the SC-2040.
Connector J12 carries the signals to and from the MIO-16E board. Use connector J11 to access
these signals. You can use this connector to monitor these signals, using a National Instruments
CB-50, for example, or you can use this connector to connect to other DAQ accessories.
Figure 3-1 shows these connectors.
