To connect RS-485 cable to the ACP Lon-
works, proceed as the following order.
• First, among the connectors that can be con-
nected to the ACP Lonworks , connect the
end of RS-485 cable connected to BUS A of
PI485 to Tx part.
Next, connect the end of RS-485 cable con-
nected to BUS B of PI485 to Rx part.
• RS-485 cable that was connected to PI485
