WARNING!
Any existing connection between the positive and minus
terminals to any evaluation system must be disconnected
in order to perform the configuration.
■ Using the cable "RJ45 / RJ45"
As an alternative, quick and easy connection is possible using
the "RJ45 / RJ45" cable included in the supplied configuration
set (only for T12.30). To do this the protective RJ45 plug, which is
delivered inserted in the front of the unit, must be removed. In its
place, the RJ45 / RJ45 cable leading to the programming adapter
(programming unit) must be inserted. In this way, the transmitter
is connected to the adapter while the connection to the evaluation
system remains in place via the plus / minus wire. In this case, it
is not necessary to disconnect the existing wiring of the transmit-
ter (positive and negative terminals), since the disconnection is
automatically triggered by switching the RJ45 plugs.
WARNING!
After configuration, the protective RJ45 plug must be
replaced into the connecter on the transmitter (otherwise
the positive and negative terminals will not work).
