1. Overview

The HygroClip DI (Digital Interface) allows connecting up to two HygroClip digital humiditytemperature 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).

3. Power supply

The HygroClip DI is shipped with a regulated 12 VDC / 100…240 VAC adapter (170 mA).

4. Probes

The HygroClip DI is designed for use with the ROTRONIC HygroClip digital humidity temperature probes. These are highly accurate probes which are adjusted entirely by means of software (no potentiometers). Because calibration and other data are stored in the probe non-volatile memory, the probes are fully interchangeable. When a probe requires adjustment / calibration or has to be repaired, it can be replaced with another probe in a few seconds.

The ROTRONIC HygroClip digital probes are available in different configurations so as to meet the requirements of each application.

The following probes have a 5-pin DAT-05 connector. An extension cable such as the MOK-02B5 is required to connect these probes to the HygroClip DI (see Accessories):

Probe Inputs

Clicking on the plus sign to the left of “Probe Inputs” expands the tree and displays probe inputs 1 and 2.

Note: the HygroClip DI accepts HygroClip probes only.

● Input Name: use a maximum of 12 characters

● Calculation: Each probe input of the HygroClip DI can be set to compute one of the

following psychrometric parameters:

Dew point (Dp) Frost point (Fp) Wet bulb temperature (Tw) Enthalpy (H) Vapor concentration (Dv) Specific humidity (Q) Mixing ratio by weight (R) Vapor concentration at saturation (Dvs) Vapor partial pressure (E) Vapor saturation pressure (Ew)

Left click on the arrow to the right of the list box and select the parameter to be calculated by the HygroClip DI for this particular probe. This is also the calculated parameter that HW4 will display for this probe.

Dew point (Dp) or Frost point (Fp): depending on the selection made here, HW4 will display

either the symbol Dp or the symbol Fp. The symbol Fp indicates that any value below freezing is a frost point as opposed to a dew point. When selected, the symbol Fp is also be displayed for values above freezing. This of course is to be understood as being the same as dew point.

● Fixed pressure value: Calculating some of the psychrometric parameters requires barometric pressure as an input. Enter here the fixed pressure value that will be used by the HygroClip DI. Note that this numerical value should be consistent with the pressure unit that was selected under Language / Unit System.

● Alarm: alarm conditions can be defined for humidity, temperature and the calculated parameter. Values that are below the low alarm value or above the high alarm value will trigger an alarm. A value can be specified for the alarm function hysteresis. This value is used for both the low and the high alarm. To trigger an alarm only in the event that a probe is missing, disconnected or not transmitting data, simply enable the alarm for one of the parameters and set the Hi and Lo values to the range of the probe (for example 0 and 100 for humidity). All versions of HW4 will show an out-of-limits value alarm in red on the monitor screen. HW4 Professional can also be configured (HW4 global settings - Alarm settings tab) to display an alarm table and generate a report whenever an out-of-limits condition occurs.

Digital Interface

This form is used to select the RS-485 baud rate between 57600 and 19200. Other data cannot be changed from within the form. Select the Baud rate depending on which devices you plan to connect with the HygroClip DI. Devices such as the HygroFlex transmitter normally use 19200 bps.

7.3 Compliance with FDA 21CFR Part II and GAMP

When used together with the validated ROTRONIC HW4 software – Professional Edition; the HygroClip DI complies with the FDA / GAMP requirements regarding electronic records and electronic signatures. HW4 is designed to keep track of configuration changes and of any probe adjustment. HW4 also keeps track of user events (main operations performed by each user) and self-events (software problems). The records generated by HW4 are protected, have an electronic signature and can be cross referenced one with the other.

7.4 Device protection

This function is used to protect the HygroClip DI against malicious users. This is particularly useful when the device is exposed to the Internet. When a device is protected, the following functions are disabled:

• All Device Manager functions

• Log function programming (HygroLog NT)

• Probe adjustment

• Deletion of files from the device memory card (HygroLog NT)

Warning:

The following HW4 automatic functions are also disabled for the protected device:

• Automatic address change when adding new devices to a RS-485 multi-drop network

8. Baud rate compatibility requirements

Depending on the model, devices from ROTRONIC use one of the following Baud rates as the factory default:

• 57600 bps: HygroLog NT data logger and docking stations

• 19200 bps: HygroPalm and HygroLab indicators, HygroFlex and M33 transmitters,

HygroClip Alarm programmable alarm card, HygroClip DI interface, HygroStat MB ThermoHygrostat

IMPORTANT:

• All devices connected to a RS-485 multi-drop network (master and slaves) must use the

same Baud rate

• In the case of a device with an Ethernet (TCP/IP) module, the Baud rate of the module

must be the same as the Baud rate of the device

Devices and internal Ethernet modules with mismatched Baud rate will not communicate together.

• The Baud rate configuration of a ROTRONIC device can be changed with the Device

Manager function (Digital Interface tab) available from within the HW4 software.

• The Baud rate of a Digi Module can be changed only from the module web interface. See

separate document IN-E-TCPIP-Conf_10.doc (also available in PDF format).

9. Ethernet local area network

ROTRONIC devices with an Ethernet (TCP/IP) interface presently use an internal module manufactured by Digi International (Digi Connect ME for a wired connection, Digi Connect WI-ME for a wireless connection). Both types of module feature a web interface that is used to configure the module.

IMPORTANT: The TCP/IP settings of both the HygroClip DI-4 and DI-4-WL should be configured to be compatible with the local area network. Detailed instructions are provided separately in document IN-E-TCPIP-Conf_10.doc (also available in PDF format).

Both the HygroClip DI-4 and DI-4-WL are shipped with a Device Configuration Certificate that provides information about the factory configuration settings of both the Ethernet module and device. See example below:

Setting Value

DHCP or Static Address Static IP Address 192.168.1.1 Subnet Mask 255.255.255.0 Default Gateway 192.168.1.0 TCP Port 2101 MAC Address 00:40:9D:28:2D:2A Firmware Release (device) 1.4 User Name (web interface) rotronic Password (web interface) wlan Serial Port Configuration Profile TCP Sockets Basic Serial Settings Baud Rate 57600 Data Bits 8 Parity None Stop Bits 1 Flow Control None

10. RS-485 multi-drop network

All models of HygroClip DI feature a RS-485 connector. When the number of available PC ports is limited, this connector can be used to connect together up to 64 HygroClip DI (or other devices) in a multi-dropped arrangement. In principle, an unlimited number of such networks can be monitored with the HW4 software, but each RS-485 multi-drop network is limited to 64 devices. The HygroClip DI can be used either as a slave or a master, without special configuration. The master is automatically the device that is directly connected to the PC or LAN by means of a USB port or TCP/IP port.

RS-485 Address: the RS-485 address is used to identify the individual devices that are connected to a RS-485 multi-drop and must be unique to each device. This address is part of the HygroClip DI communications protocol. The factory default for the RS-485 address is 00. In general, this address should not be changed manually (see note below). As far as HW4 is concerned, all masters can share the same RS-485 address. When the HW4 command “Search

Rotronic AG Bassersdorf, Switzerland

HygroClip DI digital interface: instruction manual

Page 19 of 24

for RS-485 slaves” is being used, HW4 automatically changes from 00 to 01 the RS-485 address of any master that has slaves attached. As a result, all masters end up with the same RS-485 network address (01). In addition, HW4 automatically changes the RS-485 address of the slaves in each multi-drop from 00 (factory default) to a unique address ranging from 02 to 64. The same address range (02 to 64) is used again when there is more than one multi-drop RS485 network.

Notes:

- We recommend using HW4 to give each HygroClip DI a unique name for easier identification.

- In the situation where an RS-485 network is to be monitored by software other than HW4, you will have to use HW4 to give each device a unique RS-485 address prior to connecting to the network.

Example: HygroClip DI with USB port

The number of HygroClip DI with USB port that can be directly connected to a PC depends on the number of USB ports available on the PC.

PC (HW4)

USB port

Master

Address 1

RS485

Multi-drop: up to 1000m (3300 ft)

IMPORTANT:

- If you change an instrument from master to slave, be sure to change the RS address of the instrument to 00 before establishing the RS-485 connection. Not doing so may prevent HW4 from detecting the instrument. After detecting the instrument, HW4 will automatically change the RS address to 02 or higher. Please note that HW4 may eventually change the address of any master with address 00.

- All devices within a multi-drop should use the same Baud rate. See Baud rate compatibility requirements.

- HygroClip DI-4 and DI-4-WL: please note that the Baud rate of the HygroClip DI and the Baud rate of the internal Ethernet module should be set to the same value

- The RS485 wiring can be done with a twisted pair (2-wire, telephone type) and wall mounted RJ45 receptacles. No shielded cable and no terminator should be required. observe the polarity for each connection. Using 4-wire cable, offers the option of powering all devices in the multi-drop from a single DC voltage source.

14. Electrical Installation Guidelines

Power supply wiring

Heavy machinery and instrumentation should not share the same power supply wiring. If this cannot be avoided, noise filters and surge protectors should be used. Most UPS devices have those features already integrated.

General guidelines for signal cables

The following guidelines are derived from European Standard EN 50170 for the transmission of signals by copper wires. When planning an installation, the rules provided by EN 50170 should be followed under consideration of local circumstances to determine the position of machines and equipment.

All ROTRONIC HygroClip products are tested for Electromagnetic Compatibility according to following European standards:

- EN 61000-6-3 + EN 61000-6-1 (residential)

- EN 61000-6-4 + EN 61000-6-2 (industrial)

Whenever the level of electromagnetic interference is expected to be high, both the instruments and signal cables should be placed as far away as possible from the source of interference.

In general, signal cables should be installed in bundles or channels / conduits, separate from other cables as indicated in the table below:

• Bus signals such as RS485

• Data signals for PCs, printers etc.

• Shielded analog inputs

• Unshielded direct current (<= 60V)

• Shielded process signals (<= 25 V)

• unshielded alternating current

(<= 25V)

• Coaxial cables for CRT monitors

• Direct current from 60 V to 400 V

(unshielded)

• Alternating current from 25V to 400 V

(unshielded)

• Direct and alternating current > 400 V

(unshielded)

• Telephone lines

• Lines leading into EX-rated areas

Lightning protection

Cabling in areas with a risk of lightning requires a lightning protection. For cabling underground in between buildings, we recommend the use of special fiber optic cables. If this is not possible, use copper cables that are suitable for underground installation.

Additional guidelines for RS-485 wiring (products with a serial interface)

RS-485 Cable

Using a symmetrical transmission method in combination with low capacity/ low attenuation twisted pair cables, allows extremely reliable long distance connections. The use of a high grade shielded cable avoids cross talk between the transmitted signals and also reduces the potential of external interference. For the RS-485 cable, we recommend using a cable Cat. 5e ANSI/ TIA /EIA-568-A-5.

In general the RS-485 cable should be shielded and comply with the following specifications:

- Cable capacitance <=300pF/m or 90 pF/ft

- Line impedance 100 Ω ±15 Ω

- Line resistance 140 Ω/km or 225 Ω

- Signal lines Twisted pair

In addition, we recommend terminating each end of the RS-485 cable with a 240 Ohm resistor.

Voltage potential issues

The existence of a voltage-potential between instruments that are interconnected can be a source on concern in large installations, installations with different mains power supply and in interbuilding networking.

As a first measure, the shield of a signal cable should be connected at both ends. In the case of a data cable, a low-resistance potential equalization cable may also have to be used. This cable should be run parallel and as near as possible to the data cable, preferably in the same conduit. The shield of the data cable should under no circumstances be used as equalization cable! The conductors of the potential equalization cable should ideally be stranded in order to be effective also in case of high- frequency interference.

The following points should also be observed:

• Close the parasitic circuit

• Connect all devices to the potential equalizing cable as often as possible. Electrical

conductors such as machine elements, metal tubes or supporting constructions should be integrated into the system.

• Protect the potential-equalization cable and connections against corrosion.

• Select the cross-section of the potential equalization cable according to the maximum

equalization current.

If these different measures do not correct the problem, a galvanic separation according to ISO 9549 may have to be installed. You may also want to consider the use of fiber-optic cables.
