The RS485 serial option is used to connect CAREL compatible
controllers to a supervisory network via a standard RS485 serial line. The
input normally used for the programming key is also used for this pur-
pose, having the dual function of key input / serial communication port
(only on controllers where fitted).
Assembly
Connect the RS485 option to the CAREL controllers (at the key serial
input) using the 4-wire cable; depending on the neccessity use a cable
75mm or 220mm lenght.
Make the connection to the supervisory network, as shown in Fig. 2.
The serial line should be terminated with a 1/4 W 120
Ω
resistor between
terminals TxRx+ and TxRx-.
Refer to the documents on the corresponding controllers for the
setting of the serial address and the maximum number of connections.
WARNING:
• Check the technical documents on the corresponding controllers for
the connection of the power supply, so as to avoid damaging the
instrument.
• Securely fasten the option so as to prevent it from being
disconnected. It must be fixed inside the same device as the
controller.
• Connect the wiring with the power supply disconnected.
• Keep the serial option cables separate from the power cables (relay
and power supply outputs).
