1.4 Installing the RS-232C Interface
────────────────────────────────────────────────────
WARNIN
To prevent electrical shock, before adding or replacing the RS-232C
interface, check that the power for the unit is off and the power cord
and connectors are disconnected. [The fixing screws must be firmly
tightened or the input unit may not function up to specification, or may
even fail.]
To avoid the danger of electric shock, never operate the unit with an
RS-232C interface removed. If you should wish to use the unit after
removing an interface, fit a blank panel over the opening of the removed
unit.
CAUTIO
When inserting in the interface, hold the metal plate. Directly touching the
board may cause static electricity and lead to damage of the instrument.
(Using the wrist strap for preventing static electricity when inserting is
recommended.)
.4 Installing the RS-232C Interface
The space for fitting the 9593-02 RS-232C INTERFACE in the rear panel of
the 3157 is covered with a blank panel. Follow these three steps to install the
9593-02 interface:
(1) Remove the fixing screws, and take off the blank panel.
(2) Insert the 9593-02 RS-232C INTERFACE into the exposed slot in the rear
of the unit in the figure below.
(3) Push the 9593-02 firmly into place, and fix with the screws removed in
step 1.
