NOTE: Conventions for these
drawings and tables as they
relate to pinout information:
•
2R4 means Matrix 2, Row
4.
•
1C5 means Matrix 1,
Column 5
•
4C2 bypass means: Matrix
4, Column 2, and the
connection bypasses the
100 in-rush resistor that
protects the reed relays

WARNING
WARNING:: As a safety
feature, interlock pins (17
and 33) must be shorted to
enable the Analog Bus
relays, which are on Matrix
2, to close. The optional
34933T-002 (for 1-wire)
terminal block shorts these
pins for you. This safety
feature protects inadvertent
routing of high voltages
from the Analog Buses to
the D-sub connector of the
module.
