Introduction to HMDW110 Series

HMDW110 series transmitters are accurate humidity and temperature transmitters for

measurements in HVAC and cleanroom applications. The series consists of the following

models:

• HMD110/112 models for installation in ventilation ducts

• HMW110/112 models for wall installation

• HMS110/112 models for outdoor use

HMDW110 transmitters can be ordered as:

• Loop powered models, with 2-wire current outputs for humidity and temperature

• Separately powered models, with RS-485 Modbus RTU output

HMD112, HMW112, and HMS112 are standard models that are preconﬁgured for current output at

the factory. HMD110, HMW110, and HMS110 are factory conﬁgurable models that are delivered

with customer speciﬁc output settings, including calculated humidity parameters and special

scaling of current outputs, or factory activated Modbus RTU functionality.

Loop powered current output models can be connected to Vaisala Remote Display Panel

RDP100 for real-time viewing of the measurements. HMDW110 series can also supply the

operating power to the display using only the loop power from the outputs.

HMDW110 series transmitters oer several output parameters. Relative humidity (RH) and

temperature (T) are the measured parameters, the others are calculated based on RH and T.

Check the type label on your transmitter to verify its output parameters and scaling of the

output channels.

Component Board

All HMDW110 transmitter models use the same component board, which has 2 output types:

Modbus mode (RS-485) and analog mode (current output). The output type is selected when

ordering the device. See the type label of the device to see the chosen output type.

The component board has also a service port for conﬁguration and calibration use.

You can pull out the terminal blocks from the component board for easier

installation, and to disconnect the transmitter from power and RS-485 when using

the service port.

Before using the transmitter in Modbus mode, always disconnect the terminal

block for terminals 5 ... 8 to prevent the eects of ground loop on measurements.

The RS-485 connector used for Modbus communication in the lower terminal

block will power the transmitter.

12 M211692EN-C

Connecting to Service Port

Before connecting the transmitter to a PC:

• If the terminal block for terminals 5 ... 8 is wired, pull it out. This disconnects

the transmitter from supply voltage and prevents possible equipment damage

that may be caused by ground loops. The locations of the terminal blocks and

the service port are shown in Component Board (page 12).

• If the other terminal block is wired (terminals 1 ... 4), pull it out also. This

prevents the communication between the transmitter and the RDP100 remote

display panel or Modbus (RS-485) host from interfering with your connection.

The service port is intended for a temporary connection to the transmitter. You can use it for

conﬁguration, calibration, and troubleshooting using a computer with Windows operating

system. Use Vaisala Insight software to connect to the transmitter. You also need a Vaisala USB

cable for computer connection (order code 219690).

The RS-485 line of the service port is shared with the connection to RS-485 Modbus output/

output to RDP100 remote display panel; the M8 service port connector is just an additional

connector for easier access.

Figure 8 HMDW110 Wiring with RDP100 Remote Display Panel

You must always connect the humidity measurement current loop (HUM, terminals 5 and 6) to

power the transmitter. Connecting the temperature measurement current loop (terminals 7

and 8) is optional.

Connect the RDP100 remote display panel using terminals 1 ... 4. The HMDW110 series

transmitter provides both power and data to the RDP100.

Terminals 1 ... 4 shall be used only for connecting the RDP100 (optional) when

using the analog outputs. If the RDP100 is not used, terminals 1 ... 4 must be left

unconnected. Otherwise the analog outputs may output incorrect readings.

The GND input of the RDP100 must be connected only to terminal 3 of the

HMDW110 transmitter. It must not be connected to any local ground potential.

When using the RDP100 with HMDW110 series transmitters, do not connect the

Extpwr jumper to the RDP100 component board.

Figure 9 HMDW110 Wiring, Modbus Output

Do not connect the analog outputs (terminals 5 ... 8) at the same time when

supply power and/or Modbus output is connected to terminals 1 ... 4. Having both

terminals connected simultaneously may result in erroneous analog readings

caused by eects of possible ground loop.

16 M211692EN-C

Modbus Communication

Transmitters ordered with the Modbus conﬁguration option are accessed using the Modbus

serial communication protocol. The supported Modbus variant is Modbus RTU (Serial Modbus)

over RS-485 interface.

Data Encoding

Registers using "32-bit ﬂoat" data format are encoded using the "binary32" encoding deﬁned

in IEEE 754 (also known as "single-precision ﬂoating point format").

The least signiﬁcant 16 bits of a ﬂoating point number are placed at the Modbus register listed

in the table, while the most signiﬁcant 16 bits are placed in the register with number/

address + 1, as speciﬁed in Open Modbus TCP Speciﬁcation, Release 1.0. This is also known as

"little-endian" or "Modicon" word order.

Reading the measurement data registers with incorrect ﬂoating point format setting may

occasionally result in correct-looking values. It is highly recommended to ﬁrst try reading the

register number 7938 (ﬂoating point test) to see that you have conﬁgured the ﬂoating point

format correctly on your Modbus host system.

Test Value Registers

Read the known test values from the test registers to verify the functionality of your Modbus

implementation.
