3.2.6 Switch Matrix Wiring

CAUTION: Incorrect wiring of the UMR2 to the host switch matrix can permanently damage the

UMR2 and host keyboard.

The UMR2 supports switch matrices with up to 9 select lines and up to 8 data lines. Wire the host switch

matrix to the UMR2 as follows:

Connect each of the host select lines to one of the UMR2 Matrix Select Input Terminals.

•

Connect each of the host data lines to one of the UMR2 Matrix Data I/O Terminals.

•

Connect select lines only to UMR2 Matrix Select Input Terminals. Connect data lines only to UMR2

Matrix Data I/O Terminals. Within each category, the lines can be connected in any order.

For matrices with fewer than 9 select lines or fewer than 8 data lines, leave the unused UMR2 terminals

unconnected.

Wiring details for specific keyboards can be found at the

UMR2 RevC / V1.0
