7.3 Stand-alone operation as a digital probe (PC or network)
The HC2 probes can be connected to a PC or to an Ethernet network with one of the available digital interface
adapters (see Accessories). Probe configuration and full access to all probe functions requires a PC with the
ROTRONIC HW4 software installed. Starting with firmware version 1.3, the probes accept several
communication protocols that allow users to read the measurement data without the HW4 software. When
using the standard RO-ASCII protocol, access to some of the probe functions is also possible without HW4.
For details, see document E-M-AC3000-CP.
7.4 Connectivity examples for stand-alone probes
Digital connection example: RS-485 network
Notes:
o
The master device can be either a transmitter such as the HF5 (USB or TCP/IP interface) or an adapter
such as the AC3010 cable (USB)
o
Power to the combination E2-01XX-MOD and HC2 probe can be provided by an individual AC adapter or
by a central voltage source connected to the RS-485 network (requires cables with 2 twisted pairs: one for
the data, the other for power)
