Devices are designed for indoor applications. By device type (see previous table) they can
measure ambient temperature at °C or °F, relative humidity of air without aggressive ingredients or
atmospheric pressure. It is possible to choice one of the following computed value: dew point
temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy. Devices
TRP232-105D and TRP485-105D support atmospheric pressure measurement at hPa, PSI, inHg,
mBar, oz/in2, mmHg, inH2O or kPa. They support pressure correction for altitude setting (offset).
Unit choice is provided by User’s software – see later. Devices TE232-105D, TR232-105D and
TRP232-105D communicate via link RS232, devices TE485-105D, TR485-105D and TRP485-
105D via link RS485. Supported communication protocols are Modbus RTU, protocol compatible
with standard Advantech-ADAM and ARION. Devices are preset from manufacturer to Modbus
RTU communication protocol. If you would like to use different communication protocol then
Modbus RTU, it is necessary preset them throw user’s software – see latter. Temperature, relative
humidity eventually pressure sensors are non-removable device parts, pressure sensor is placed
inside the electronic case. Measured and computed values are optionally shown on dual line LCD
display. If there are two values displayed at one LCD line, they are periodically switched between
both readings with period of 4 seconds. Display can be switched OFF totally too. Please read
instruction manual before the first device connection.
Use user’s software Tsensor for setting of all device parameters (recommended). It
supports make the adjustment of the device too. This procedure is described at file „Calibration
manual.pdf“ which is installed commonly with the software. Change of some parameters is possible
to do without user’s software with Windows hyperterminal (change of communication protocol, its
parameters, LCD display setting).
Device setting from the manufacturer
If special setting was not required in the order device is set from the manufacturer to the following
parameters:
communication protocol: Modbus RTU
device address: 01H
communication speed: 9600Bd, without parity, 2 stop bits
display: switched ON
value displayed at higher line: temperature (temperature / pressure) – by device type
value displayed at lower line: relative humidity only – by device type

temperature unit: °C
pressure unit: hPa
correction for altitude: 0 hPa(absolute pressure)
preset computed value: dew point temperature
Device installation
Devices are designed for indoor applications. It is recommended to mount them on universal
wiring box (common installation box KU68) with using two enclosed mounting screws. For correct
function there is necessary to find proper device place. It shouldn’t be placed at places where it can
be affected by sunshine, near radiators, heating elements and other heat sources, air handlers,
windows, doors, into racks and shelves and similar places. For buildings with less thermal
insulation there is not suitable to place them on external walls of building. If there are
communication conductors placed into conduit, there is strongly recommended make it caulk, to
restrict air flow around device.
Connect cables to terminals with respecting the signal polarity (see figure). Terminals are
self-clamping and can be opened by a suitable screwdriver. For the opening, insert the screwdriver
to upper terminal hole and lever by him.
There are two ways, how to power devices with RS232 interface. They can be powered
either from master device or from external power source. For powering from master device RS232
interface there is necessary to interconnect DTR and RTS signals with the device. For powering
from external power source, there is necessary to connect positive power terminal to DTR into
device terminal only and then do NOT interconnect DTR and RTS with master device.
Devices with RS232 interface:

GND Shielding, power source ground
Tx Output data for master device, transmit
Rx Input data from master device, receive
RTS Connect with RTS signal to master device, eventually o not connect
DTR Connect with DTR signal to master device or connect positive power terminal from
external power source
Devices with RS485 interface contain “doubled” connection terminals to provide continuous
connection of next RS485 devices. Terminals description:
Terminal Connect to
A+, B- RS485 communication line
Shielding of communication line
+U, GND Power source positive terminal, power source ground
For devices with RS485 interface here is recommended to use shielded twisted copper cable
(e.g. SYKFY), maximal length 1200m. The cable must be located at indoor rooms.
Nominal cable impedance should be 100 Ω, loop resistance max. 240 Ω, cable capacity
max. 65 pF/m. Suitable cable is e.g. SYKFY 2x2x0.5 mm2, where one wire pair serves for the
device powering and the other pair for communication link.
The cable should be led in one line, i.e. NOT to „tree“ or „star“. Termination resistor should
be located at the end. For short distance other topology is allowed. Terminate the network by a
termination resistor. The value of the resistor is recommended about 120 Ω. For short distance
termination resistor can be left out. The cable should not be led in parallel along power cabling.
Safety distance is up to 0.5 m, otherwise undesirable induction of interference signals can appear.

The same for devices with RS232 interface, but a maximal length is restricted to 15 m and
allow connect only one device.
Electrical system (wiring) may do only worker with required qualification by rules in
operation.

Device mounting
Firstly mount back part of device onto wiring box with two holding screws. Connect cables to
terminals with respecting the signal polarity (see figure). Terminals are self-clamping and can be
opened by a suitable screwdriver. For the opening, insert the screwdriver to upper terminal hole and
lever by him. Then insert front part of device firstly at bottom into hinge and then press both parts
together – see figure1
Figure1: Device mounting
Device demounting
If there is necessary demount the device, insert flat bladed screwdriver max. 3.5 mm wide
from top side into middle device’s air hole. There is fastening member placed, insert screwdriver
beyond the fastening member about 2 cm deep – number cat the picture. Then slightly move
screwdriver in arrow direction das shown at the picture. It unlock fastening member and the
device is partially opened. Remove the screwdriver and take front part of device at top, see number
eat the picture. Pull front part with pendulum motion, remove front cover, numbers fand gat
the picture.
If there is necessary remove back part of device, please disconnect cables and unscrew two
holding screws.

Figure2: Device demounting
Button and jumper - placing
Button is placed behind small hole on the left side of the device (front
view). For button pressing use thin instrument, for example paper clip. Button
function is described later.
Jumper is available only after the front part of device is demounted. Then
look at the back side of demounted front part. Jumper is placed at the right
bottom corner (at the same side as button). Jumper function is described later.
Info mode
If in doubt of setting of installed device, verification of its address is enabled even without
using computer. Devices with RS232 interface have address always set to one.
Power should be connected. Shortly press Button (jumper should be opened). Actual adjusted
address of the device is displayed on LCD display at decimal base. Next press of button exits info
mode and actual measured values are displayed.
Note: No measurement and communication is possible during info mode. If device stays in info
mode for longer than 15 s, device automatically returns to measuring cycle.
Setting of pressure correction for altitude
For devices TRP232-105D and TRP485-105D only! If there is necessary to read value of
atmospheric pressure corrected with respect to altitude, it is possible to set corresponding pressure
offset for this altitude. It is possible to do it with Users software. This value is then automatically
added to measured pressure value. The resultant value of pressure with added correction for altitude
must be between 300 hPa and 1350 hPa (from 4.351 PSI to 19.580 PSI). Outside this range device
sends value of Error 2!

Description of communication protocols
Detailed description of each communication protocols including examples of
communication is available in individual document.
Note: After switching ON the power of the device it can last up to 2 s before the device starts to
communicate and measure!
Modbus RTU
Control units communicate on master-slave principle in half-duplex operation. Only master can
send request and only addressed device responds. During sending of request no other slave station
should respond. During communication, data transfer proceeds in binary format. Each Byte is sent
as eight bit data word in format: 1 start bit, data word 8 bit (LSB first), 2 stop bits1, without parity.
Device supports communication speed from 110Bd to 115200Bd.
Sent request and response have syntax: ADDRESS OF DEVICE – FUNCTION – Modbus CRC
Supported functions
03 (0x03): Reading of 16-bit registers (Read Holding Registers)
04 (0x04): Reading of 16-bit input gates (Read Input Registers)
16 (0x10): Setting of more 16-bit registers (Write Multiple Registers)
Jumper and button
Jumper and button are located next to connection terminals. If communication protocol
Modbus is selected the function of jumper and button is as follows:
•Jumper opened – device memory is protected from writing, from device side it is only
enabled to read measured value, writing to memory is disabled (no change of device
address, communication speed and LCD setting is enabled)
•Jumper closed – writing to device memory is enabled by means of User’s software
•Jumper opened and button shortly pressed – device goes to Info mode, see chapter „Info
mode“
•Jumper closed and button pressed for longer than six seconds – causes restoring of
manufacturer setting of communication protocol, i.e. sets Modbus RTU communication
protocol, device address sets to 01h and communication speed to 9600Bd (after button press
there is “dEF” message blinking at LCD display. Six seconds later message “dEF” stays
shown, it means manufacturer setting of communication protocol is done).
1Device sends two stop bits, for receive one stop bit is enough.

•R register is designed only for reading
•W* register is designed for writing.
•Xregister addresses are indexed from zero – register 0x31 is physically sent as value
0x30, 0x32 as 0x31 (zero based addressing).
Note: In case there is a need for reading of measured values from the device with higher resolution
than one decimal, measured values in device are stored also in „Float“ format, which is not directly
compatible with IEEE754.

Protocol compatible with Advantech-ADAM standard
Control units communicate on master-slave principle in half-duplex operation. Only master can
send requests and only addressed device responds. During sending request any of slave devices
should respond. During communication data is transferred in ASCII format (in characters). Each
Byte is sent as two ASCII characters. Device supports communication speed from 1200Bd to
115200Bd, parameters of communication link are 1 start bit + eight bit data word (LSB first) +
1 stop bit, without parity.
Jumper
Jumper is located next to connection terminals. If communication protocol compatible with
standard Advantech-ADAM is selected, its function is the following:
•If jumper during switching ON the power is closed, device always communicates with
following parameters regardless stored setting in the device:
communication speed 9600 Bd, without check sum, device address 00h
•If jumper during switching ON the power is not closed, device communicates in accordance
with stored setting.
•If jumper is closed during device operation, device temporarily changes its address to 00h, it
will communicate in the same communication speed as before closing jumper and will
communicate without check sum. After jumper is opened setting of address and check sum
is reset in accordance with values stored in the device.
•Communication speed and check sum are possible to change only if jumper is closed.
•Jumper closed and button pressed for longer than six seconds – causes restoring of
manufacturer setting of communication protocol, i.e. sets Modbus RTU communication
protocol, device address sets to 01h and communication speed to 9600Bd (after button press
there is “dEF” message blinking at LCD display. Six seconds later message “dEF” stays
shown, it means manufacturer setting of communication protocol is done).
For communication with device which measure more than one value, there is necessary to add
at the end of command, number of communication channel, where the measured value is mapped.
Command for value reading is #AAx(CRC) CR, where AA is device address and xis number of
communication channel by next table:

Error States of the device
Device continuously checks its state during operation. In case error is found LCD displays
corresponding error code:
Error 0
First line displays „Err0“.
Check sum error of stored setting inside device’s memory. This error appears if incorrect writing
procedure to device’s memory occurred or if damage of calibration data appeared. At this state
device does not measure and calculate values. It is a serious error, contact distributor of the device
to fix.
Error 1
Measured or calculated value except in pressure is over upper limit of allowed full scale range.
There is a reading „Err1“ on LCD display. Value read from the device is +999.9. (for pressure
reading there is +999.9 hPa correct value)
This state appears in case of:
•Measured temperature is higher than approximately 600°C (i.e. high non-measurable
resistance of temperature sensor, probably opened circuit).
•Relative humidity is higher than 100%, i.e. damaged humidity sensor, or humidity
calculation of humidity is not possible (due to error during temperature measurement)
•Computed value – calculation of the value is not possible (error during measurement of
temperature or relative humidity or value is over range)
Error 2
There is a reading „Err2“ on LCD display. Measured or calculated value is below lower limit of
allowed full scale range. Value read from the device is -999.9.
This state appears in case of:
•Measured temperature is lower than approximately -210°C (i.e. low resistance of
temperature sensor, probably short circuit).
•Relative humidity is lower than 0%, i.e. damaged sensor for measurement of relative
humidity, or calculation of humidity is not possible (due to error during temperature
measurement)
•Measured pressure value with added correction for altitude is outside of range from
300 hPa to 1350 hPa (from 4.351 PSI to 19.580 PSI) or the pressure sensor is damaged.
Please check setting of pressure correction for altitude with User’s software.
•Computed value – calculation of computed value is not possible (error during measurement
of temperature or relative humidity)
Error 3
There is a reading „Err3“ on LCD display upper line.
Error of internal A/D converter appeared (converter does not respond, probably damage of A/D
converter). This error does NOT affect pressure measurement. Rest values are NOT measured. It is
a serious error, contact distributor of the device.
10

Error 4
There is a reading „Err4“ on LCD display. It is internal device error during pressure sensor
initialization. Under this condition device does NOT measure atmospheric pressure. Value read
from device is -999.9. Pressure sensor is probably damaged. It is a serious error, contact distributor
of the device.
