RS485-IN interface of the first device. The first processor must be
Master Mode, the other must be Slave Mode.
Use Cat 5e cable to connect RS485-OUT interface of the first
device with RS485-IN interface of the second device.
Use Cat 5e cable to connect RS485-OUT interface of the second
device with RS485-IN interface of the third device.
As step 3, use Cat 5e cable to connect multi devices. One PC can
be connected with three models of device ( 4 in 8 out, 2 in 6 out, 2
in 4 out) . The maximum number of connections are 32 processors.
Finally, RS485-OUT of the last device is connected with the
terminal resistor via Cat 5e cable.
