17.1.1 Connecting the Cable
ATTENTION:
By using the RS-232C/AUX interface of the PBS/PBJ type balances it is also
possible to output other signals than RS-232C ones. Incorrect connection of those
signal cables may lead to the personal computer or balance failure. Therefore, make
sure that the suitable and correctly connected cable provides communication
between the balance and computer.
Some types of computers may not operate normally when they are connected by
using the optional RS-232C cable in the way shown in the below figure.
(1) IBM PC/AT computer and compatible (9-pin D-sub connector)
(2) IEEE standard (D-sub 25-pin)
