4.2.2 Aardvark Adapter
Although the Total Phase Aardvark adapter will physically mate to the EVM J3 connector, the pinout is
incompatible. A special interface cable must be constructed to use the Aardvark. Refer to the schematics
and Table 7 below for information.
CAUTION
Do not connect the Aardvark to the EVM without a properly constructed cable.
Damage may result to the EVM and/or Aardvark.
