Switch and Jumper Settings

TX-2000 Card

To assign memory addresses, the TX-2000 switches should be set for each span.
The TX-2000 switches are located near the bottom left center of the TX-2000 card
and include several rocker-type switches. These can be set to either an On or Off
position. Jumpers for the TX-2000 card are located just to the right of the
switches.
The diagrams below for the TX-2000 show the switch settings for each span on
the left and the jumper settings for each span on the right. The Memory Address
and Interrupt Request (IRQ) level are also defined for each span.
Refer to the following figures when setting your span type:
