RS485 Ports
The CN100 controller has one RS485 port to some specific
equipment. Each port has five terminals: 485 A+, 485 B-, chassis
ground and termination. See the following picture for the RS485 pin
assignment.
Figure 4-7: Pin Assignment of RS485 Port
The regulations are recommended to follow:
n
All chassis ground terminals of RS485 must be connected to the
earth.
n
Use single shielded two wire twisted cable.
RS485 Terminals: A termination resistor (120-ohm) is used within
CN100 controller to match the characteristic impedance of the cable
