Multidrop communication

Multidropping transmitters refers to the connection of several transmitters to a single communications
transmission line. Communication between the host and the transmitters takes place digitally with the
analog output of the transmitters deactivated.
Multidrop installation requires consideration of the update rate necessary from each transmitter, the
combination of transmitter models, and the length of the transmission line. Communication with
transmitters can be accomplished with Bell 202 modems and a host implementing HART protocol.
