RAD-Star operates at a nominal 12V and requires 300 mA of current at that voltage level, but
will accept equivalent power input at a range of 4.5V to 36V.
If your test bench does not have a suitable cable to power the RAD-Star, you can make
one from a female DB-9 connector and appropriate wiring; the pinout can be found in
Table 2, with pin numbers shown in Figure 7
. Note that the LIN and CAN interfaces are for
internal use by Intrepid; the only end-user function of this cable is to supply DC power, so you
only need to connect pin 9 and one of the ground pins.

Hardware Setup - Active Tap
In this section we explain the process of setting up the RAD-Star step by step. Note that
while the directions are listed in a particular order, the exact sequence in which the setup is
performed does not affect operation.
The instructions that follow assume that any necessary cables have already been fabricated or
modified as described in the previous section.
Figure 8 shows you at a glance how to set up the cables to use the RAD-Star as an active tap.
