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.

2 Service port connector (4-pin M8)
3 Terminal block for RS-485 output. For Modbus or RDP100 remote display panel
connection.
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.

Wiring HMDW110
Wiring Devices with Analog Output
HMDW110 series transmitters are designed for a supply voltage range of 10 ... 28 VDC. The
minimum required voltage depends on the loop resistance (0 ... 600 Ω) as shown below.

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.

Wiring Devices with Modbus Output
Use terminals 1 ... 4 for supply power and Modbus output. In addition to RS-485 data wires, the
common wire (ground reference) must be connected between the RS-485 host and the
HMDW110 transmitter.

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.

Download Insight software at www.vaisala.com/insight.
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.

Measurement Data Registers
Accessing unavailable (temporarily missing) measurement data does not generate an exception.
“Unavailable” value (a quiet NaN) is returned instead.
Measurement output is shown in metric units. If non-metric values are needed in Modbus use, the
units shall be converted in the Modbus master (PLC) using the scaling functions typically available.

Vaisala Insight Software
Vaisala Insight PC software can be used to check, configure, and adjust HMDW110 series
transmitters intuitively without typing any serial commands. The transmitter can be connected
to Insight software using a Vaisala USB cable for computer connection (order code 219690).
With the Insight software, you can:
See device information and status.
See real-time measurement.
Configure serial communication settings, filtering factor, and analog output parameters
and scaling.
Calibrate and adjust the device.
Insight software guides you when changing the settings and performing adjustments on the
transmitter. However, please read carefully the chapters on calibration and adjustment in
HMDW110 Series User Guide (M211726EN) before performing adjustments on your HMDW110
device.
Download Insight software at www.vaisala.com/insight.
HMDW110 transmitters support Insight from transmitter software version 2.2.3
onwards.
Connecting to Insight Software
Computer with Vaisala Insight software installed
USB connection cable (order code 219690)
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.
1. Open the Insight software.
2. Connect the USB cable to a free USB port on the PC.
3. Connect the USB cable to the service port of the transmitter.
4. Wait for Insight software to detect the transmitter.
If the transmitter is not detected, disconnect and reconnect the Vaisala USB cable to the
service port connector of the transmitter.
