※

It is recommended to use Autonics communication converter; SCM-WF48 (Wi-Fi to RS485 USB
wireless communication converter, sold separately), SCM-US48I (USB to RS485 converter, sold
separately), SCM-38I (RS232C to RS485 converter, sold separately).
Please use twisted pair wire, which is suitable for RS485 communication, for SCM-WF48, SCM­US48I and SCM-38I.

●Ordering of communication control

1. The communication method is Modbus RTU.

2. After 2.0 sec being supplied the power into master system, it is able to start communication.

3. The initial communication is started by master system. When a command comes out from the
master system, THD will respond.

●Communication command and block

The format of query and response.
Query

Address code Command Start address Number of data CRC16

①

Address code: This address code is for identifying THD by master system and able to set within
range of 01 to 31.

②

Command: Read command for input register

③

Start address: The start address of input register to read (start address). It is available to select
0000 and 0001 for start address. 16-bit data in the address 0000 indicates temperature value, 16­bit data in the address 0001 indicates humidity value. (refer to Modbus Mapping table.)

④

Number of data: The number of 16-bit data from start address (no. of Points). When start address
is 0000, it is available to read 2 of 16-bit data, or when start address is 0001, it is available to read
1 of 16-bit data.

⑤

CRC16: Checksum for checking the whole frame and it is used for more reliable transmit/receive
to check the error between transmitter and receiver.

Response

Address code Command Number of data Temperature data Humidity data CRC16

①

Address code: This address code is for identifying THD by master system and able to set within
range of 01 to 31.

②

Command: A response for read command of input register

③

Number of data: The number of 8-bit data to send from start address (no. of bytes). When start
address is 0000, it is available to read 4 of 8-bit data, or when start address is 0001, it is available
to read 2 of 8-bit data.

④

Temperature data: This is the value of 16-bit. To get a current temperature value, divide read value
by 100.
E g.)When read data is 0×09B0, decimal value is 2480, the current value is 2480/100=24.80

⑤

Humidity data: This is the value of 16-bit. To get a current humidity value, divide read value by 100.
E g.)When read data is 0×0B68, decimal value is 2920, the current value is 2920/100=29.20%RH.

●Setting communication speed

1. Turn off the power of the unit.

2. Set SW1 to 0 and supply the power.

3. Operation indicator LED is flashing.

4. Set a communication speed after choosing SW1 within the

range 1 to 8, and hold it for 3 sec.

5. After setting a communication speed, the LED will be ON.

At the moment turn OFF the power.

※

Factory default communication speed is 9600bps.

●Setting communication address

1. Set upper address setting terminal and setting switch (SW1) to the desired address and supply the power.

2. The communication address is changed automatically.

※

Factory default communication address is 01.

Comprehensive Device Management Program

[DAQMaster]

DAQMaster is comprehensive device management
program. t is available for temperature and humidity
monitoring.
For more information, please refer to the DAQMater
user manual.

Cautions during Use

1. Follow instructions in 'Cautions during Use'. Otherwise, t may cause unexpected accidents.

2. Keep away from high voltage lines or power lines to prevent inductive noise.

In case installing power line and input signal line closely, use line lter or varistor at power line and

shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high frequency noise.

3.

Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.

4. 24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power supply
device.

5. Do not overlapping communication line and power line.
Use twisted pair wire for communication line and connect ferrite bead at each end of line to reduce

the e󰀨ect of external noise.

6. Do not touch TDH-W/D sensor part at the bottom of the sensor pole by hands.
It may cause malfunction.

7. THD-R must be installed on the wall.

It may cause malfunction.

8. Make a required space around the unit for radiation of heat.
For accurate temperature measurement, warm up the unit over 20 min after turning on the power.

9.

Make sure that power supply voltage reaches to the rated voltage within 2 sec after supplying power.

10. Do not wire to terminals which are not used.

11. This unit may be used in the following environments.

Indoors (in the environment condition rated in 'Specications')
