Option 01

The Option 01 Smart Card (Master) is required for use in all 1260
switching systems. This option acts as the switching system
master, and all other switching modules are slaved to it. It turns
any number of modules into a message-based VXIbus switching
system.
The smart card is addressed over the VXIbus, and all other
modules resident in the VXIbus chassis are controlled by this card.
Option 01 uses the local bus on the VXI P2 connector to provide
scanning, delay and exclude capabilities.
The built-in-test features in the smart card include confidence
checking which monitors the state of each relay. It monitors a
spare set of contacts or sensing coil current to ensure the
switching system configuration is as programmed.
Refer to Section 2 for software installation procedures for the
1260-01, and to Section 3 for the software command set used to
control the switching modules. The sections on individual modules
describe the device specific installation and programming for each
module.
