Please read all of the sections of
this
chapter which apply to your com-
puter before proceeding with the installation of your HP 27140A Multi-
plexer.
Installing
this
PCA involves the following steps:
1.
Unpacking and examining the card (temporary storage
is
also
discussed).
2. Inserting the card into the computer card cage.
3. Testing the
unit.
4. Attaching MUX-to-Junction Panel, Modem, and RS-232-C direct
connect cables.
After installation, the card is configured by programmatic instructions.
Many of the components of the HP 27140A are
susceptibl~
to destruction
or degradation by electrostatic discharge. See the safety considerations in
the front of
this
manaul. To handle this card,
use
only the edges and ex-
tractor levers to avoid damage to components.
/~
There
is
no site preparation required for
this
product other than proper
installation of the host computer.
Using the MUX
will
require that several cables be attached to the RS-232-
C Junction Panel. Consideration must be given to locating the RS-232-C
Junction Panel mounting bracket so that these cables present no problems
to traffic or maintenance of the computer. The RS-232-C standard limits
the length of cable from the card itself to any terminal device to a total of
15
metres
(SO
feet).
