For the settings about the RS-485 port look at chapter 6 “CONFIGURATION”.
MICRO-SWITCH
Micro-switch to:
- plug in the termination of the RS-485 port (120 Ω, 0.25 W); position micro-switch 1 on position ON to plug in the termination of
the RS-485 port (plug in the termination of the first and of the last element of the network)
page 18 of 116
EVCO S.p.A. c-pro 3 | Hardware manual ver. 3.2 | Codice 114CP3E324
- polarize the network of the RS-485 port (560 Ω, 0.25 W); position micro-switches 2 and 3 on position ON to polarize the
network of the RS-485 port (the network must be polarized by an element of the network same).
- plug in the termination of the CAN port (120 Ω, 0.5 W); position micro-switch 4 on position ON to plug in the termination of the
CAN port (plug in the termination of the first and of the last element of the network).
CAN BUS
CAN port.
Terminal Meaning
CAN + signal +
CAN - signal -
GND ground
The maximum number of devices that can make a CAN network (32) depends on the bus load; the bus load depends on the baud rate
of the CANbus communication and on the kind of device in the network.
For example: a CAN network can be made of a programmable controller, of four I / O expansions and of four user interfaces
with baud rate 500,000 baud.
The maximum length of the connecting cables of the CAN port depends on the baud rate of the CANbus communication, as
follows:

GND ground
The maximum number of devices that can make a CAN network (32) depends on the bus load; the bus load depends on the baud rate
of the CANbus communication and on the kind of device in the network.
For example: a CAN network can be made of a programmable controller, of four I / O expansions and of four user interfaces
with baud rate 500,000 baud.
The maximum length of the connecting cables of the CAN port depends on the baud rate of the CANbus communication, as
follows:
- 1,000 m (3,280 ft) with baud rate 20,000 baud
- 500 m (1,640 ft) with baud rate 50,000 baud
- 250 m (820 ft) with baud rate 125,000 baud
- 50 m (164 ft) with baud rate 500,000 baud.
