INSTALLING AN XVME-910 CHANNEL EXPANSION KIT

A.1
INSTALLATION
The number of analog inputs on the XVME-500/590 can be expanded from 16 single-
ended/8 differential to 32 single-ended/l6 differential by installing an XVME-910
Channel Expansion Kit.
The kit consists of two additional 8 input analog multi-
plexers. Installation is simply a matter of positioning the two integrated circuits on
the board in locations U19 and U23, and soldering them in place (see Appendix C,
the assembly drawing for the locations of these IC’s).
NOTE
Static precautions should be taken when handling the
chips, and a low-wattage soldering iron (30 watts or
less) should be used.
Care should be taken to make sure pin 1 on the chip
is aligned correctly.
