To connect the Coordinated Measurement Bus
(CMB)
Caution Be careful not to confuse the 9-pin connector used for CMB with those used by
some computer systems for RS-232C communications. Applying RS-232C signals
to the CMB connector is likely to result in damage to the HP 64700 Card Cage.
To use the CMB, you will need one CMB cable for the first two emulators and one additional cable for
every emulator after the first two. The CMB cable is orderable from HP under product number
HP 64023A. The cable is four meters long.
You can build your own compatible CMB cables using standard 9-pin D type subminiature connectors
and 26 AWG wire.
Note that Hewlett-Packard does not ensure proper CMB operation if you are using a self-built cable!
Connect the Coordinated Measurement Bus.
Connect the rear panel BNC.
