FEATURES
Compatibility
with Racal
Instruments 1260-
Series
The 1260-100 /101 Adapt-a-Switch Carrier uses the same
Option-01T controller as conventional Racal Instruments
1260-Series switch modules. A single Option-01T Switch
Controller Module may control up to twelve switch modules or
plug-ins. This may include a combination of 1260-Series and
Adapt-a-Switch plug-ins. A single Option-01T will not control more
than one 1260-101.
See Chapter 2: Getting Started for instructions on combining
1260-Series modules and Adapt-a-Switch plug-ins in the same
VXIbus chassis.
Ease of Use
The 1260-100/101 includes several ease-of-use features (the
1260-100 model is shown in Figure 1-3):
•
Plug-ins are easy to insert and extract from the front panel of
the 1260-100/101, even while it is installed in a chassis.
•
For only the1260-100, module addresses, used to uniquely
identify each plug-in, are set by a single DIP switch that is
easily accessible from the side panel of the 1260-100. See
Setting Configuration Switches in Chapter 2: Getting
Started for instructions.
•
The 1260-100/101 ejector handles also function as injectors,
making it easy to install the carrier into a VXIbus chassis.
Maintainability
Maintainability of the 1260-100/101 is enhanced by the fact that
plug-ins are removable from the front panel. This has the following
benefits:
•
The mean time to repair (MTTR) is minimized, since the carrier
does not need to be disassembled or even removed from the
VXIbus chassis.
•
The switch system may be easily upgraded in the field by
adding or changing plug-ins.
•
Sparing is less costly and more flexible, since individual plug-
ins may be spared rather than the entire 1260-100/101 module.
