34934C-002 Configuration Block: 8x32 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
–
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 8x32”
–
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”
–
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”
–
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 Row Setting Jumpers on the 34934C-002
Placing ID Jumpers on the 34934C-002 Configuration Block for 8x32
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:
To set the correct ID code for 8x32, place two vertically positioned jumpers in the
left position, as shown below.
