The values for the transmission distance, baud rate and number of stations
should be within the values noted in the following graph.
x
Transmission distance [m]
y
Number of stations
For a baud rate of 115200bit/s
Q
For a baud rate of 19200bit/s
W
3)
Set the baud rate in the system registers and set the DIP switch on the bottom
of the unit to the same setting. When a C-NET adapter is connected to the
RS485 interface, you can only specify a baud rate of 19200bit/s.
4)
The start and end code can only be used in program controlled communication.
5)
Station numbers should be registered via the system registers.
If the potential difference between the power supplies of RS485 de-
vices exceeds 4V, communication may fail because the RS485 port
is non-isolated. The large potential difference will damage the con-
nected devices.
