Power

The IDM-L35 requires 5 V DC for operation, which can be applied to one of the three power

supply board connectors (see page 3). The RDK includes a USB serial cable that provides

power via the serial header connector. In all cases, the power supply must be regulated

within the electrical limits listed in Table 1.

Wiring

Figure 3 shows all possible electrical connections, including RS232, analog inputs, and

digital I/O. The actual functionality of the peripheral connections is determined by the

application software.
