1.4 Power
The receiver module is designed for embedded applications and requires a regulated +5.0
VDC input (+4.75 to +5.25 VDC). See Power Requirements in Chapter 4 for detailed
specifications. In the Starter Kit, the motherboard includes a DC power regulator which
converts a 9 to 32 VDC input to the regulated 5 VDC required by the module. Power can
be applied to the Starter Kit module using one of two options: the DC power cable (see
Figure 1-8) or the AC/DC power converter (see Figure 1-9).
Figure 1-8. DC Power Cable
The DC power cable is ideal for bench-top or automotive testing environments. The power
cable is terminated at one end with a 3-pin plastic connector which mates with the power
connector on the metal enclosure. The unterminated end of the cable provides easy
connection to a DC power supply. Connect the red power lead to a source of DC positive
+9 to +32 VDC, and connect the black power lead to ground. This connection supplies
power to both the receiver module and the antenna. The combined power consumption of
the receiver module and the antenna is 200 milli-amps.
