7 Operation

7.1 HF52 and HF53 transmitters (analog outputs)

Use the HW4 software to configure the HF5 as desired, complete the mechanical and electrical installation,

connect the probe and simply power up the HF5.

7.2 HF53 with digital option and HF55

Both the HF53 with digital option and the HF55 use the standard RO-ASCII protocol and do not offer any other

option. Users who wish to read the measurement data without the HW4 software should consult ROTRONIC.

The different types of digital interface available with the HF5 are best used with a PC with the HW4 software

installed (version 2.1.0 or higher). In principle, users should be able to use communication software other than

HW4 to read measurement data from the HF5. In this case, communication is limited to the RDD (data

request) and REN (RS-485 address change) commands described separately in document E-M-AC3000-CP.

IMPORTANT: Depending on the type of digital interface, either the PC or the HF5 must be configured

by the user as indicated below.

a) USB connection

Prior to connecting the HF5 to a USB port you must install the ROTRONIC USB driver on the PC (available

from the HW4 CD or from www.rotronic-humidity.com). For instructions see the HW4 manual E-M-HW4v3-

Main (§ 7.3)

b) Ethernet (TCP/IP) connection (wired or wireless)

Prior to connecting the HF55 to an active Ethernet network you must configure the TCP/IP settings of the

HF55 using either the HW4 software (version 2.1.0 or higher) or the TCP/IP configuration tool available from

www.rotronic-humidity.com. For instructions see the HW4 manual E-M-HW4v3-Main (§ 7.4) and technical

note IN-E-TCPIP-Conf

WARNING: Connecting a device to an active Ethernet network can disrupt communications on the network.

Before connecting the HF5, make sure that it is properly configured for your network

c) RS-485 serial interface (multi-drop)

Instructions for using the HF5 with a RS-485 network are provided in the following manuals:

E-M-HW4v3-Main (§ 7.5), E-M-HW4v3-F2-005 and E-DV04-RS485.01.

Notes:

o Instruments connected to the same RS-485 network must use the same baud rate and each instrument

must be given a unique RS-485 address (the address requirement applies to the HF5 but not to its probe)

o RS-485 Compatibility: The communications protocol used by the HF5 is the RO-ASCII protocol. This

protocol is not compatible with the protocol used by the previous generation of ROTRONIC products. Do

not connect legacy products and the HF5 to the same RS-485 multi-drop network.
