*1 The standard baud rate should be 9600 baud, but 384000 baud can be used if to transmit at higher speeds.

*2 Both male and female connectors are provided to simplify connection between devices.

*3 Set the devices connected to the RS-485 bus to high impedance, except when transmitting.

Before a transmission, make sure that the bus is set to high impedance, to avoid signal collision on the bus.

*4 Dp indicates even number parity.
