INM MTL83xC PC Modbus Rev 4
Notice that the module MAC address is displayed as well as some firmware version information for
the Ethernet Port. After this there are four sections numbered 1, 4, 5, and 7. This is the main menu
and these are the 4 optional areas to configure.
This is a text-based interface to the Ethernet Port and the menu item is selected by typing the item
number. It then will ask one question at a time and give an opportunity for entering the necessary
data.
The above information is the default setting of the port. Notice that it comes set up for DHCP
which means it would be looking for the network to supply it an IP address. Most likely you will
want to change this to a fixed IP address. It is not likely that changes will be needed for options
4 or 5. In most cases the defaults work. For security reasons the Ethernet port has been locked
down to prevent bad actors from accessing the device. This is seen by all of the Disabled settings in
menu item 7. We do not recommend enabling any of these options. We have set an Enhanced
Password even though all ports are disabled. There is no need for you to know the password as you
can change it using this software. It is only needed for accessing the ports from the network – but
they are disabled by default.
Here is an example of setting the IP address to 10.0.0.62, Gateway to 10.0.0.254, and Netmask to
255.255.255.0:
Notice we typed “1” to select Network / IP Settings and were then asked for the IP Address – one
byte at a time. The default value is in parenthesis, so we entered ‘10’ and pressed <Enter>. Then
since zero is what we wanted for the second byte, we just press <Enter> - likewise for the third
byte. Finally we enter “62” for the fourth byte. In a similar fashion we entered the Gateway and
Netmask. We did not enter a password because it is a weak password. The Enhanced Password in
the Security section is better. After pressing <Enter> for the password the port repaints the menu
with the updated information.
Note: Setting the IP Address to 0.0.0.0 will cause the Ethernet port to get its IP address from a DHCP
server.
