2 Base Matrix Configuration
48 Keysight 34934A User’s Guide
To set the correct ID code for 4x32, place two horizontally positioned jumpers as
shown below.
Placing Safety Interlock Continuity Jumpers for 4x32 At the bottom (end
opposite the D-Sub connectors) of the terminal block are two 20-pin extension
headers—marked J24 and J25 on the circuit board. These headers provide access
to the module’s rows. Pins 19 and 20 on each header must be shorted to provide
continuity for the module’s safety interlock function.
Two keyed 20-pin terminators are supplied for providing safety interlock
continuity. Install the terminators securely in the headers, as shown below.

The ID jumpers MUST correspond to the matrix configuration set by the
CONFIG jumpers in the previous step. The instrument firmware functions
based on the ID it detects from the (ID) jumper positions and assumes the
CONFIG jumpers are set accordingly.
