 The RS485 host port can be operated on a multi-drop bus (multiple power supplies
connected to a single host, all using the same communications cable). The host (master) is
always listening unless sending a command. Slave units are always listening for
commands unless sending a response. Slave units only respond to commands that
contain their address.
* The baud rate is selectable, see B.1.19:Unit Settings Command “t”: to set the baud rate
using the host port. See 6.3.2:Host Port Configuration to set the baud rate using the
control panel.
