1. Features
SmartDEN IP-32IN is an Ethernet input module designed especially for remote
monitoring and logging. It provides 16 digital inputs (for motion detector sensors, dry
contacts, switches, buttons), 8 analog inputs (for temperature, humidity, light,
pressure sensors) and 8 NTC inputs especially designed for thermistors type
B57500M. The integrated web server for set-up, SNMPv2c and HTTP/XML allow
easy embedding in other systems. The module is able as well to control other remote
relays based on input event or work in "Data Logging Mode" in order to post data in
xml format on a remote server.
A list of SmartDEN IP-32IN features includes:
Inputs:
16 digital inputs (counters) with ON/OFF LED;
8 analog inputs 0-10V DC;
8 temperature inputs for NTC thermistors type B57500M;
Linearization (scaling) for the analog inputs;
Communication:
Fully Compatible with 10/100/1000 Base-T networks, Auto-MDIX;
Protocols: TCP/IP, HTTP, DHCP, DNS, ICMP (ping), SNMPv2c;
Web Interface:
Configuration of system parameters;
Access current measurements;
Secure login authorization;
Access protection (by IP and MAC address);
TCP/IP Services:
HTTP server: Access (GET) current measurements in XML/JSON format;
Encrypted login process for reading inputs status and analog/temperature
values;
SNMP:
SNMP messages for configuration/monitoring (get, set, bulk, table, getnext,
walk);
SNMP trap messages (triggered by threshold events or periodically);
Web Services:
Data Logging mode (push) mode: XML data is sent via HTTP post method to
remote server periodically;
Remote relay control mode: remote control of smartDEN Relay Modules,
DAEnetIP3, DAEnetIP4 and Wi-Fi Relay Modules through Ethernet/Internet;

2. Application examples
SmartDEN IP-32IN could be used for home and industrial automation
applications, datacenters monitoring, environmental monitoring and so on. Several
application examples how SmartDEN IP-32IN could be used are shown bellow. The
examples are only conceptual and an additional equipment/connections can be
required in actual implementations.
2.1. Remote sensors monitoring
This mode of the module SmartDEN IP-32IN allows monitoring up to 32 different
sensors in real time. Various kinds of sensors for temperature, humidity, distance,
light and so on can be connected to the device. In this mode SmartDEN IP-32IN acts
as a server. A custom client application can retrieve the current measurements using
SNMPv2c or HTTP GET requests. Examples of client applications include our iOS
and Android mobile apps, as well as custom monitoring applications with SNMPv2c
/HTTP/XML/JSON support.
Figure 1. Remote sensors monitoring
2.2. Push messages and data logging
Another very useful mode of SmartDEN IP-32IN is sending "push" messages
(notifications) to remote server without the need to be polled continuously. This is
very suitable for organizing alert and logging systems. The module is able to send
HTTP POST messages in XML format periodically. The SNMP traps can be triggered
by events (for example when temperature is getting high) or send periodically. It is

also possible to control remote relay board over the LAN/WAN network again basing
on input event via HTTP GET request.
Figure 2. Alert and data log example system
2.3. Events counter
SmartDEN IP-32IN provides 16 x 16-bit counters (from 0 up to 65535) attached to
the digital inputs that can be used to count various not fast events - for example
detect when a person enters in a shop through the door (Fig. 3). Upon detecting the
specified edge/level condition SmartDEN IP-32IN increments the corresponding
counter. With suitable software and database one could easily organize a simple
monitoring and statistic system.

5.2. Power supply
Figure 6. SmartDEN IP-32IN power supply
SmartDEN IP-32IN must be with voltage either 12VDC or 24VDC stabilized and
filtered. After power on, the power led must be on and STATUS indicator must start
blinking in 5 seconds which means the module is running normally.

Please keep the polarity and supply voltage range!
SmartDEN IP-32IN 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.

5.5. Communication setup
SmartDEN IP-32IN 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:
