Ethernet 10/100-BASE-T
HT22IoT 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.
