Base Matrix Configuration 2
Keysight 34934A User’s Guide 107
Also note the four extension headers (J3, J4, J5 and J6). Instructions for wiring to
these are provided in “34934C-001 Configuration Block: Wiring” on page 113.
34934C-001 Configuration Block: 4x128 Jumper Configuration
The configuration block has five types of jumpers which must be connected to
configure it for use in an expanded 4-row matrix. In this section, you will place:
– ID Jumpers: place these 2-pin jumpers on a 2x3 block of jumper pins near the
bottom center of the board. See “Placing ID Jumpers on the 34934C-001
Configuration Block for 4x128” on page 107.
– CONFIG Jumpers: place these 2-pin jumpers identically on all four 4x2 blocks
of jumper pins located near the board’s female D-Sub connectors. See
“Placing CONFIG Jumpers on the 34934C-001 for 4x128” on page 108.
– Row Extension Jumpers: place these 16-pin jumpers on a 16x3 block (J7) of
jumper pins at the board’s center. See “Placing Row Extension Jumpers on the
34934C-001 Configuration Block” on page 110.
– Row Access Jumpers: place these 16-pin jumpers on a 3x16 block of jumper
pins located just above the ID Jumpers. See “Placing Row Access Jumpers on
the 34934C-001 Configuration Block” on page 111.
– Safety Interlock Continuity Jumpers: place the supplied pre-wired
terminators on the four 20-pin extension headers at the sides of the
configuration block. See “Placing Safety Interlock Continuity Jumpers on the
34934C-001 Configuration Block” on page 112.
Placing ID Jumpers on the 34934C-001 Configuration Block for 4x128
The
ID jumpers allow the 34980A to recognize the base matrix configuration used by
the 34934C-001, upon mainframe bootup. The ID jumpers are placed in a 2x3
jumper block, located below jumper block J8. Jumper placement guidance is
provided on the configuration block’s silk-screen, to the right of the jumpers:
To set the correct ID code for 4x128, place two horizontally positioned jumpers in
the right position, as shown below.
