Baud rates
adjustable minimum response time
a
The JUMO digiLine protocol assigns the interface parameters automatically during startup (Plug & Play).
b
The Modbus RTU protocol is used to operate the JUMO digiLine electronics on a JUMO mTRON T CPU. For op-
eration on a JUMO mTRON T, the interface parameters must be set prior to initial commissioning with the JUMO
DSM software.
