BU-xH8D Base Unit
The SmaRT BU-xH8D base unit features eight FET, 2.5A (8A max total) high-side switching
outputs/inputs capable of digital or pulse-width-modulation (PWM) control @ 30
–200Hz. It
accepts an input power operating voltage range from +7 to +28VDC. The base unit provides a
robust link with a handheld remote in congested radio environments using Direct Sequence
Spread Spectrum (DSSS) wireless technology broadcasting 900MHz @ 10mW and 2.4GHz @
100mW.
SmaRT base units feature seamless association to a SmaRT handheld remote control unit
without the need to open either the remote or base unit case. All controlled apparatus
connections to the base unit are made using a single wiring harness cable.
The compact base unit enclosure is constructed of rugged, heavy duty high-impact polymer.
VDC power to the unit and output signals are ported using the heavy duty 12-pin connector
(Figure 2) and wiring harness (Figure 6) that connects to connector P1. Power can be removed
from the base unit by disconnecting the cable harness connector from P1.

The unit has twelve status/diagnostic LEDs that are used to determine the state of the unit.
Figure 3 illustrates the LEDs and indications.
