1. Overview
The HygroClip DI (Digital Interface) allows connecting up to two HygroClip digital humidity-
temperature probes to a PC, either by means of a USB port or by means of a wired / wireless
TCP/IP network (LAN / Internet). The HygroClip DI can also be used to connect to a PC other
instruments from ROTRONIC that have a RS-485 port such as the HygroFlex and M33
transmitters, HygroLab 2 indicator, etc.
The HygroClip DI is designed to operate with the ROTRONIC HW4 networking software (v 1.2.2
or higher). Other than the capacity of the PC, there is no limit to the number of HygroClip DI that
can be networked with the PC.
The main functions of the HW4 software include on-line data monitoring and recording by the PC,
automatic generation of graphs and data tables, configuration of the HygroClip DI, and
adjustment (calibration) of the HygroClip probes connected to the HygroClip DI.
The main features of the HygroClip DI are as follows:
● Two probe inputs (HygroClip probes)
● Choice of USB or Ethernet interface - wired or wireless
● RS-485 port for connecting up to 64 devices to a multi-drop network.
Power for the HygroClip DI is normally provided by an external AC adapter. The RS-485 port also
allows powering the HygroClip DI and other devices in a multi-drop network from a single DC
power source (user supplied).
