LOGIC INPUTs
The two logic inputs are opto-isolated.
The connection cable should not be channeled with power cables .
The function of the two inputs is as follows:
INPUT 1* TARE/ZERO
INPUT 2 PRINT
The activation of the two functions is accomplished by bringing the
external 24 VDC power supply to the corresponding terminals as
shown in the figure here beside.
* Activating the INPUT 1 when the gross weight is positive, it switches
the display from gross weight to net weight. When the gross weight
is negative, gross weight is zeroed.
SERIAL COMMUNICATION
RS232:
The RS232 serial port is always present and can handle several
protocols.
To achieve the serial connection use a suitable shielded cable and
make sure to ground the screen at one of the two ends: to pin 13,
if attached on the side of the instrument, to the ground, if connected
on the other side.
The cable must not be channeled with power cables, maximum
length of 15 meters (EIA RS-232-C), beyond which you should take
the optional RS485 interface.
RS485:
The RS485 serial port (2-wire) is only present in the model DAT
100/RS485.
To achieve the serial connection use a suitable shielded cable and
make sure to connect the shield to one of two ends: to pin 13, if
connected on the side of the instrument, to the ground if connected
on the other side.
The cable must not be channeled with power cables.
RELAY OUTPUTs
The two outputs are with contact normally open.
Each contact is 24 Vdc / Vac, Max. 1 A.
The connections cable should not be channeled with power cables.
The connection should be as short as possible.
