The Rosemount SAM42 can be interfaced directly to the Process/
Distributed Control System (PCS/DCS), or to a permanent server
running Fieldwatch software, or to a service computer running the
SAM42 Acoustic Particle Commissioning application. See diagrams
below reflecting all interface options.
6.1.1 Interface to a service laptop running SAM42 Commissioning
app
To configure and calibrate the SAM42 device, a service PC running
the SAM42 commissioning app is required. The service PC should be
connected to the SAM42 device via the SAM42 commissioning cable.
The commissioning cable contains both the RS485-USB converter and
a battery power supply for the SAM42.
