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 100Ω in-rush resistor that

protects the reed relays

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.
