increases the value by 1. Increasing the value when the digit 9 is displayed sets 0
when editing the most significant digit results in the change to the digit sign - the
changing the parameter value will cause the write to be canceled.
5.5. Connection of the device – configuration
5.5.1. Connection of the recorder to the networ equipped with a DHCP server
The easiest way to connect HT25 recorder to Ethernet is to use the existing
DHCP server, which assigns communication parameters, i.e. IP address, subnet
mask, gateway, DNS address to the devices being connected.. In order to use the
automatic configuration with DHCP server, makesure the recorder is running with
DHCP client service enabled - - to do this, switch on the power of the recorder and
observe the initial messages :
a) message about the recorder operation with DHCP
client enabled – the displayed IP address is the
current address of the recorder acquired from DHCP server;
b) message about the work of the recorder with
disabled DHCP client service - the displayed IP
address is the current address of the recorder set
manually or the default address (after restoring the default parameters); in order to
obtain the address from the DHCP server, restore the recorder to the factory
parameters, point 5.2, and restart the device - then a) message should be
displayed with the IP address obtained from the DHCP server.
In order to further configure the device a computer (tablet, phone) must be
connected to the same Ethernet network (also with DHCP client enabled -
automatic acquisition of IP address), open a web browser and in the browser

HT25-0 9 User’s Manual 12
address field type the IP address displayed by HT25. This will display the login
screen to log the web server that will allow further configuration - sign up to the
administrator account, p. 5.6.3.2.
After gaining access to the full configuration we recommend that you disable
the DHCP client, leaving the acquired network parameters unchanged – IP
address, subnet mask, gateway, DNS address will be stored as static parameters.
5.5.2. Connecting the recorder to the networ without using DHCP server
In order to use the automatic configuration with DHCP server, make sure the
recorder is running with DHCP client service disabled - to do this, switch on the
power of the recorder and observe the initial messages:
a) message about the recorder operation with
DHCP client service enabled – the displayed IP
address is the current address of the recorder acquired from DHCP server; to set
the a static IP address factory parameters should be restored, p. 5.2, and the
device should be restarted – then a message should be displayed b) with the static
default IP address.
b) a message about the recorder operation with
disabled DHCP client service - the displayed IP
address is the current address of the recorder set
manually or the default IP address (after restoring the default parameters), if the
displayed address is different from 192.168.1.19 the factory defaults should be
restored twice, p. 5.2;
In order to further configure the device a computer (tablet, phone) must be
connected to the same Ethernet network (or directly to the recorder) and the
automatic acquisition of network parameters must be disabled. Then, the static
parameters corresponding to the default network parameters of HT25 must be
manually entered into the computer (tablet, phone) p. 5.6.2 (the same subnet mask
and any IP address from the pool 192.168.1.X except for the address 192.168.1.19
assigned by default to HT25). After the connection, open your web browser and
type the default IP address 192.168.1.19. in the address field of the browser. This
will display the login screen to log the web server that will allow further configuration
- sign up to the administrator account, p. 5.6.3.2. After logging in to the recorder
web server it is possible to change the network parameters according to our needs
- especially the IP address must be changed to make sure that the recorder does

HT25-0 9 User’s Manual 13
not have the default IP address, otherwise the configuration of other recorders
working in the same Ethernet network will be difficult.
5.4. Functions of the recorder
The HT25 recorder acts as the master of the MODBUS RTU network,
reading data from connected devices. To do this, configure the RS- 85 port of the
recorder to work in "Master" mode. The recorder's "Slave" mode is used to update
the software. The recorder can read data from max. 10 devices, and it can read up
to 10 registers (10 channels) from each device. The Modbus function of reading n-
registers is used to read data from devices (number 3) or the function of reading
input registers (number ). If you need to read more registers from a given device,
you must configure separate channels to read the same device with different base
addresses. The configuration of the recorder to work in master mode is possible via
the embedded web server.
5.4.1. Configuration of the RS-485 interface of the recorder
The main panel of the web server contains the "Modbus" window, after clicking it,
the user can configure the recorder to poll devices via the Modbus protocol on the RS- 85
link. It is possible to configure 10 channels. Channel No. 8 is dedicated to temperature /
humidity transducers / probes (P18, P18D, P19) but can be used to connect any device.
The "Modbus" configuration window consists of three tabs:
1) RS- 85 - global parameters of the RS- 85 interface – transmission – the ability to
set the speed, parity check, operating mode and in Master mode the permissible number of
incorrect responses and the maximum response time, see fig. 9.
Fig. 9. View of the "RS-485" tab of the "Modbus" window

HT25-0 9 User’s Manual 1
2) Channels - configuration of Modbus Master channels – configuration of the polled
device: address, Modbus function selection, initial register number, number of registers,
type of registers being polled, polling interval and selection of displayed values on the main
web server window (tile dedicated for a given channel) and name definition of the channel

HT25-0 9 User’s Manual 15
While working in master mode, the recorder polls the devices in the network, and
the data read from them is available in data registers (registers 8000 ... 8099 - channel 1
8000 ... 8009, channel 2 8010 ... 8019, etc.). The devices are polled in the order according
to the configuration (channel 1, channel 2, channel 3, etc.), the frequency of device polling
depends to a large extent on the speed of devices operating on the bus. For devices with a
long response time, it may happen that the time between subsequent data readings from
the device is longer than the time set in the recorder configuration. The time difference
results from the waiting time for the device response and the duration of data transfer. In
the case of setting a long waiting time for the response and the lack of device from which
the readings are to be taken, the recorder waits for the time (specified by the "response
time" parameter) each time the request is sent, therefore, if the device is switched off from
the network, disable it in the recorder by setting address value to "0" (disable polling for a
given channel).
5.5. Description of H 25 recorder reading field
HT20 is equipped with a backlit LCD display consisting of two lines of 16
characters each.. The top line of the display is used for the presentation of
measured values - e.g. temperature and relative humidity and to display status
pictographs of the file system internal memory. Bottom line of the display shows
the internal memory usage, alarm status, time and date. During normal operation
the recorder displays measured values alternately with their symbols.

5.7. Ethernet 10/100-BASE-
HT25 recorders are equipped with Ethernet interface for the connection
(using RJ 5 slot) to a local or global network (LAN or WAN) and the use of network
services implemented in the recorders: Web server, FTP server, Modbus Slave
TCP/IP, SMTP client. In order to use the network services Ethernet parameters of
the recorder must be configured. Standard Ethernet parameters of the recorder are
shown in table 4. The basic parameter is the IP address of the recorder - by default
192.168.1.19, which must be unique within the network to which we connect the
device. The IP address can be assigned to the recorder automatically by DHCP
server present on the network provided that the the option to acquire IP address
from DHCP server is enabled. DHCP service is disabled by default, then the
recorder initializes with the default IP address allowing the user to change the IP
address through the website.
Caution: The recorder allows for up to 10 connections simultaneously!!
The applications implemented in the recorder use from 1 to 2 connections:
●Modbus TCP/IP - 1 connection
