.2 Shipping Precautions
If reshipping the unit, preferably use the original packing.
If this is not available, use the following procedure.
(1) Wrap the unit in plastic sheeting.
(2) After wrapping cushioning material around the unit, pack it into a
cardboard box, and then seal up the box with adhesive tape.

.3 Notes on Use
(1) If you change the communication conditions of the 3157 while using it, you
should immediately turn the power off and on again. If you do not do so, the
communication conditions will not be changed to the new ones.
(2) Always be sure to secure the RS-232C cable to the 9593-02 unit by tightening
up the fixing screws provided.
(3) Program messages sent just after the power has been turned on are executed
after the self test has terminated.
(4) It is vital that the proper data format is used when inputting commands with
data values to the 3157 unit.
(5) For details of the various functions, refer to the instruction manual for the
3157 unit.

1.4 Installing the RS-232C Interface
────────────────────────────────────────────────────
WARNIN
G
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
N
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.

.1 Introduction to the RS-232C Interface
By connecting the 9593-02 RS-232C INTERFACE to the 3157 AC
GROUNDING HiTESTER, it is possible to control all the functions of the
main unit (except for powering on and off) via the RS-232C bus.

.2 Features
(1) All of the functions of the 3157 main unit, except for powering on and off, can
be controlled via the RS-232C interface. However, the ":STARt" command
works in a state in which the momentary OUT settings are disabled even
though the momentary OUT settings have been set.
(2) The beeper sound can be turned on and off.
(3) The unit can be reset.
(4) Test results can be printed on the optional 9442 PRINTER.
(5) Connecting with the optional 3155 LEAK CURRENT HiTESTER enables
testing and the test results can be saved and printed together with the 3155
leakage current test results.

(1) Controls when receiving
When the receiving buffer is more than 85% full, CA (RTS) is set to Space to
indicate to the controller that the empty buffer capacity is low.
Processing of data in the buffer continues, and when the receiving buffer is
less than 25 % full, CA (RTS) is set to Mark to indicate to the controller that
there is ample buffer capacity.

Press the 0ADJ key while holding down the SHIFT key to release the remote
state by the RS-232C and resume the local state. However, this key operation
is disabled if the RS-232C controller has put the unit into the local lock out
state. (Pressing SHIFT +0ADJ has no effect.)
When the unit enters the remote state because of a command message, it is
forcibly returned to the READY state.
