Ethernet 10/100-BASE-T
HT20IoT monitors are equipped with Ethernet interface for the connection (using
RJ45 slot) to a local or global network (LAN or WAN) and the use of network services
implemented in the monitors: Web server, FTP server, Modbus Slave TCP/IP, SMTP client.
In order to use the network services Ethernet parameters of the monitor must be
configured. Standard Ethernet parameters of the monitor are shown in
table 4
. The basic
parameter is the IP address of the monitor - 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 monitor automatically by DHCP server present on the network provided
that the option to acquire IP address from DHCP servers is enabled in the monitor. DHCP
service is disabled by default, then the monitor initializes with the default IP address
allowing the user to change the IP address through the website.
Caution:
The monitor allows for up to 10 connections simultaneously!! The applications
implemented in the monitor use from 1 to 2 connections:
●
Modbus TCP/IP
- 1 connection
●
Web server - minimum 1 connection
●
FTP server
- 2 connections
●
SMTP client
- 1 connection
5.6.1. Connection of 10/100 BASE-T interface
To access the Ethernet services, it is required to connect the monitor to the network
via the RJ45 slot located at the top of the monitor, operating in accordance with TCP/IP.
