Factory Configuration
As shipped from the factory, the CN2 connector allows the
TARE, MAX/MIN and RESET operations be made in the same
way as from the front-panel keyboard and incorporates one
more function: the display HOLD.
If the user programs a '0' (no function) to all input pins, they
are automatically set to the default configuration.
CN2 : FACTORY DEFAULT CONFIGURATION
PIN (INPUT) Function Number
PIN 1 (INP-1) RESET Function nº 7
PIN 2 (INP-2) HOLD Function nº 9
PIN 3 COMMON
PIN 4 (INP-4) TARE Function nº 1
PIN 5 (INP-5) PEAK/VALLEY Function nº 6
The external electronics (fig.66.2) applied to the CN2
connector must be capable of withstanding 40 V and 20 mA
present at all terminals with respect to COMMON. In order to
guarantee the electromagnetic compatibility, please refer to
the instructions given on page 12.
5.2 - Logic Functions
The rear connector CN2 provides 4 user programmable opto-coupled inputs that can be operated from external contacts or
logic levels supplied by an electronic system. Four different functions may be added to the functions available from the front-
panel keys. Each function is associated to one of the CN2 connector pins (PIN 1, PIN 2, PIN 4 and PIN 5) and is activated by
applying a falling edge or a low level pulse to the corresponding pin with respect to common (PIN 3).
Each pin can be assigned one of the 36 functions listed on the following pages.
