2 Base Matrix Configuration
192 Keysight 34934A User’s Guide
– Row Access Jumpers (J8)
– Row Setting Jumpers (J15 and J16)
Also note the four extension headers (J3, J4, J5 and J6). Instructions for wiring to 
these are provided in “34934C-002 Configuration Block: Wiring” on page 198.
34934C-002 Configuration Block: 16x32 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-002 
Configuration Block for 16x32” on page 192.
– 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-002 Configuration Block for 16x32” 
on page 193.
– 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-002 Configuration Block” on page 194.
– 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-002 Configuration Block” on page 195.
– 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-002 Configuration Block” on page 197.
Placing ID Jumpers on the 34934C-002 Configuration Block for 16x32 
The 
ID jumpers allow the 34980A to recognize the base matrix configuration used by 
the 34934C-002, 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:
