Base Matrix Configuration 2
Keysight 34934A User’s Guide 167
The following illustration shows jumper blocks J15 and J16, along with the
relevant guidance provided on the board’s silk-screen for jumper placement.
For a base configuration of 8x64, place two 2x8 jumpers on each of blocks J15
and J16, as shown below.
Placing Safety Interlock Continuity Jumpers on the 34934C-002
Configuration Block
At each side of the configuration block are a pair of 20-pin
extension headers. On the right side are labeled J3 and J4; on the left side are J5
and J6. In all cases, pins 19 and 20 are the safety interlock pins.
These headers provide for row extension and row signal access, depending on the
placement of the jumpers in J7. You must have set the jumpers to extend rows
either to the left or right side of the configuration block (see “Placing Row
Extension Jumpers on the 34934C-002 Configuration Block” on page 164).
To provide continuity for the module’s safety interlock function, pins 19 and 20 on
both extension headers on the selected side (left or right) must be shorted.
– For each of these headers, install one of the supplied keyed 20-pin terminators
securely in that header, as shown below.
The supplied terminators incorporate both the shorting jumper for pins 19 and
20 and a jumper precluding connection to pins 1 and 2.
