Signal Specification
General
All values below are measured between the relevant terminal in column 1 and terminal #2F in column 2 (power ground). Unless otherwise stated in parenthesis after the table entry.
NOTE:
It is important to connect the breakout box and check the ground terminals before taking readings.
