Technical information

2.1 Options Overview
The option specifications include the following, where applicable:
• Functional information
• Ordering information
• Performance
• Configuration information
• Related documentation
Unless otherwise noted, operating system support and diagnostic support
for all options are the same as for the KA670 CPU module, as listed in
Section 1.6.
2.1.1 Configuration
Options must be properly configured so that the system recognizes them.
Each option in a system has a device address, commonly referred to as
a control and status register (CSR) address, and an interrupt vector that
must be set when the option is installed. Options are usually configured by
setting switches or jumpers on modules already configured at the factory
or Digital service representatives configure the option when they install it
in your system.
Self-maintenance customers
can find information on setting CSR addresses
and interrupt vectors in the Microsystems Options volwne of the Entry
Systems Service kit.
