Installation consists of mounting the device, connecting to an IP network,
connecting the relays, providing power and configuring via a web browser.
5.1. Box mounting
Figure 2. Mounting the device to DIN rail
smartDEN IP-16R-MT can be mounted to a standard (35mm by 7.55mm) DIN rail.
Attach the module to the DIN rail by hooking the hook on the back of the enclosure to
the DIN rail and then snap the bottom hook into place.

5.2. Power supply
Figure 3. smartDEN IP-16R-MT power supply
Depending on the selected model during purchase the power supply source for
smartDEN IP-16R-MT must be with voltage either 12VDC or 24VDC stabilized and
filtered. After power on, the power led must be on and Led1 indicator must start
blinking in 5 seconds which means the controller is running normally.
Figure 4. Connecting a LAN cable
Please keep the polarity and supply voltage range!
smartDEN IP-16R-MT does not accept AC supply voltage. It is highly
recommended to check the power supply source parameters before supply
the module.
The power supply equipment shall be resistant to short circuit and
overload in secondary circuit.
When in use, do not place the equipment so that it is difficult to disconnect
the device from the power supply.

5.3. Relay connection
Figure 5. Connecting a lamp to relay
smartDEN IP-16R-MT has 16 SPDT relays with parameters specified in the
technical parameters section. Every relay channel has normally open (NO) and
normally closed (NC) contacts connected directly to the terminals.
If you are connecting inductive loads to the relays an extra measures must
be taken in order to ensure the proper work of the device. For more
information please refer to this link:

5.5. Communication setup
smartDEN IP-16R-MT is shipped with the following default parameters:
IP address: 192.168.1.100
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
Web password: admin
Initially it is recommended to connect the module directly to the computer.
Next you have to change your PC‟s IP address.
You can google how to change you computer IP settings or just visit this
web page: http://www.howtochangeipaddress.com/changeip.php
For Windows 7 OS for example you can do that in the following way:
Navigate to Control Panel -> Network and Internet -> View network and status
tasks -> Change adapter settings
Then just select the local area connection with right click and select Properties:

6.2. Steps for loading default settings
When necessary, the factory (default settings) may be applied so the module
parameters will be returned back as those in point 6.1 from the current document.
Figure 14. Loading the default settings
1. Turn off the power supply of the device;
2. Press and hold the default button;
3. Turn on the power supply of the device;
4. Wait for until both led indicators (led1 and led2) become ON (approximately 10
sec);
5. Release the default button;
6. The module is configured with default settings.

7.1. Login
Figure 17. Login page
Enter the password and click "Login" button. This will bring you to the smartDEN IP-
16R-MT main configuration page which contains details for the current firmware
version and build date and provides buttons and links to obtain further details.
Note: The default password is admin (passwords are case sensitive).
Note: When the password is entered, it is transmitted across the network in
encrypted form, so eavesdropping on the data transmission will not reveal the
password.
Note: In order to prevent setup/control conflicts, at any given moment, only one user
can be logged in.
Note: If there is no data traffic between the Web-browser and the smartDEN IP-16R-
MT for time, specified by Session Timeout parameter, the session "times out" and a
new login is required.

Device Name: The name of the module (max 15 symbols). Every module can
have different name in your network so they can be distinguished;

Save Outputs: When checked, each time the relays state is changed, it will
be saved in non-volatile memory (EEPROM), so after reboot/restart it will be
restored;
This option should be used with care in dynamic systems because of
restriction in maximum write cycles of the EEPROM (usually 100 000
write/erase cycles).
Password: The password used for logging into the web admin and XML
operation (max. 10 chars);
When typed. the password in this screen is not hidden. Only in this case,
when the password is being changed, it is transmitted across the network
"in the open". Therefore, set passwords in a secure environment where
you can make sure that no one is "eavesdropping". Subsequent
transmissions of the password to "login" onto the device are encrypted and
"safe".
Save button: Once you have changed the settings as required, click this
button.

Enable DHCP: This option allows DHCP to be enabled or disabled. If DHCP
is set to Enabled, the Network page must be saved and smartDEN IP-16R-
MT must be rebooted before obtaining an IP address;
IP address: This is the IP address of the smartDEN IP-16R-MT. It needs to
be manually assigned only if DHCP is disabled. With DHCP enabled, this field
displays the currently assigned address;
Gateway: This specifies the IP address of the gateway router. It is used for
accessing public time servers for automatic time synchronization;
Subnet Mask: This is the subnet mask for the network on which the
smartDEN IP-16R-MT is installed;
Primary DNS: Primary DNS (Domain Name Service) address;
Secondary DNS: Secondary DNS address;
Save button: Once you have changed the settings as required, click this
button.
You have to reboot the device for these settings to apply.
