Electrical Interface
The electrical interface for power and control circuitry is provided via a connector located on the
bottom (non-component) side of the board. The connector is a 14-pin keyed shrouded header
connector as shown in Figure 1 - 3.
The UtiliNet SBR requires a nominal 5 VDC supply, with a total input range of 4 to 7 VDC. An
onboard regulator will drop the voltage to 3.4 VDC for the circuitry.
