Page: 12 / 38

4�3�- DIGITAL OUTPUT
The device is equipped with 4 digital transistor outputs, terminals 7, 8, 9, 10 and 11 of
Table 3�
4�4�- CONFIGURATION
As the device has no keypad, the setup parameters must be sent to the device via Modbus/RTU©
commands, or using the
CIRCUTOR
PowerStudio Software, which can be downloaded for free from the
web site www.circutor.es.
All
MODBUS
map addresses are hexadecimal.
4�4�1- CONFIGURATION OF THE COMMUNICATION PARAMETERS
Two options are available for this:
4�4�1�1�- Using the peripheral number
The device has the following default communication parameters: peripheral 4, 19200/8/N/1 . The
following records are available for changing the peripheral number or speed:

4�4�1�2�- Using the serial number (BROADCAST)
The serial number of the device can be found on the device's side label ( E.g.: 1280000001 ). This
number must be translated into hexadecimal language so that the sentence can be sent to the device
in broadcast format (peripheral 00):
1280000001 (Decimal) → 4C4B4001 (Hexadecimal)
