About the Model 494.40 I/O Carrier Board
The Model 494.40 I/O Carrier board is a VME
board where you can install up to four
mezzanine cards. These cards perform a variety
of functions, such as transducer conditioning,
valve driving, and other I/O functions.
Note The Model 494.40B board is a new
generation release of the 494.40 board
that is compatible with the old boards.
Your system hardware-mapping software
provides the controller software with the I/O
carrier board and individual card addresses.
The I/O carrier board includes two RJ-50 front-
panel connectors for each mezzanine card.
These connectors route signals to and from the
card.

controlled LED indicator. The LED

software.
