3.2 Connecting configured mTRON modules
The mTRON modules are connected to the recorder using a screened twisted
pair. The pre-configured mTRON modules are labelled according to customer
specification.
Example: 1 paperless recorder and 2 analog input modules
In the example shown, two analog input modules are connected to the record-
er in the “line structure” type of connection. The physical ends (recorder and
module 2) must be fitted with a termination resistor.
The bus termination resistor (50
Ω
) of the recorder is activated through a wire
link between pin 4 and pin 8 (see Chapter 3.1 “Connection diagram”).
Further details on the bus termination of the analog input modules can be ob-
tained from the installation instructions for the modules.
