Installation Guidelines
SUN-2242 controller must be installed by qualified personnel.
Controller must not be installed directly outdoors.
SUN-2242 must not be used for medical, life saving purposes, or for any purpose where its
failure could cause serious injury or the loss of life.
This unit must not be used in any way where it's function or failure could cause significant
loss or property damage.
The first step is to establish communication between computer and SUN-2242 controller.
This can be done by assigning a temporary IP address to the computer.
For computers with Windows OS assigning of IP address is made in “Local area connection
properties” or “Wireless Network Connection Properties”.
IP Address of the computer should be at the same network.
Into the web browser you should type http://192.168.2.2. If network settings are correct the
login page will appear.

Web Pages
Login Page - access to the SUN-2242 is protected by name and password
Status Page - Monitoring parameters
S U N - 2 2 4 2 U s e r M a n u a l v 1 . 1 P a g e 6

Status page has 4 sections – “Digital inputs”, “Analog inputs”, “Outputs” and
“Sensors”.
Digital Inputs section can be used for monitoring sensors in “dry contact”(volt
free) mode - motion PIR sensors, Water Leak sensors, Water level sensors,
Door/window sensors, Smoke detectors.
One side of the sensor is connected to IN1 or IN2 terminal and the other is
connected to GND terminal.
Please note that Digital inputs are not galvanic isolated!
Analog Inputs section can be used for monitoring directly batteries, power
supplies, solar panels and any analog sensor with voltage up to 60V DC.
Please note that Analog inputs are not galvanic isolated!
Outputs section can be used to open/close garage door and control motors,
pumps, valves, lights …
For loads greater than 3A/30V DC an external relay should be used.
Sensors section can be used for control 5x1-Wire sensors for temperature and
humidity.
Maximum cable length when is used UTP cable is 50m.

Network Settings page – configuration of network parameters
Device name – up to 15 characters.
MAC address – hardware address of the device. It is unique and cannot be changed.
IP address – The SUN-2242 IP address configuration can be either static or set
through DHCP.
Enable DHCP - allows device automatically obtain a valid IP address from Gateway
Gateway – default gateway IP address
Subnet mask – local network mask
Primary DNS – needs to be set properly for correct operation. Domain Name Service
associates host names with IP addresses. Without a correctly configured DNS
server, the following functions will not work:
- Time synchronization (SNTP), used in e-mails and SNMP traps
- E- mailing (SMTP)
HTTP Port – The TCP port used for HTTP communications with SUN-2242. A default
setting for this port is 80. Value of HTTP port can be changed from 80 to 65500. It is
recommended that the port be left unchanged unless the user has an understanding
of TCP/IP and ports

Sensor Settings
This page is used to configure temperature and humidity sensors.
Up to 5 x 1-Wire sensors can be connected to the SUN-2242.
Every 1-Wire sensor comes with a unique ID. After a sensor is connected must to find it
by click on the button "Find sensors".of Status web page.
S U N - 2 2 4 2 U s e r M a n u a l v 1 . 1 P a g e 10

Name – can be entered a description up to 15 characters
ID – unique number for each sensor
Type – Temperature or Humidity
Measured value – the value that sensor is reading.
Lower range - value below this range are considered to be “incorrect” and alarm event
occurs
Upper range - value above this range are considered to be “incorrect” and alarm event
occurs
Hysteresis – hysteresis is used to avoid multiple alarms when the measured value
fluctuate.
Trap – device send a SNMP Trap when alarm event occurs and this option is checked
E-mail - device send an E-mail when alarm event occurs and this option is checked
After connecting new sensors or changing RJ11 connections, click again on the
button of the Status web page “Find sensors”.

SNMP Settings
The Simple Network Management Protocol - SNMP, is a commonly used service that
provides network management and monitoring capabilities. SNMP offers the
capability to poll network device and monitor data. SNMP is also capable changing
the configurations on the host, allowing the remote management of the network
device. The protocol uses a community string for authentication from the SNMP client
to the SNMP agent on the managed device.
The SNMP Settings page allows you to configure the settings for communication with the
device using the SNMP protocol v2.0.
SNMP settings
SNMP - Enable / Disable communication by SNMP
SNMP Port – communication port for SNMP protocol. Default port is 161.
Write Community - The community is authorized to write values to variables over
SNMP. The default write community string is “private”.
Read Community - The community is authorized to read values to variables over
SNMP . The default read community string is “public”.
Trap settings
Trap - Enable / Disable sending trap messages
Trap IP address – IP address of the trap destination
Trap community – default trap community is “public”
Traps are sent in following conditions:
dry contact inputs change their status
S U N - 2 2 4 2 U s e r M a n u a l v 1 . 1 P a g e 12

measured value on analog inputs goes outside the range
measured temperature or humidity goes outside the range
Email Settings
Mail server address can be set by hostname or IP address.
SUN-2242 supports TLS 1.0, TLS 1.1 and TLS 1.2 encryption. This ensures
successful send emails with most of the public email servers .
When TLS encrypted connection is selected, the connection to the email server will be
securely. TLS generally requires the use of port 465.
By default SMTP port is 25, without encrypted connection,. Sender e-mail, username, and
password are standard authentication details.
There is a button for test email settings with a feedback.

Inputs / Outputs Settings
Name - this text field describes the function of the selected input or output. Up to 15
characters may be entered.
Digital inputs – used for direct connection of volt-free contacts. One side of the contact
is connected to Input1 or Input2 and the other side is connected to terminal in the
middle – GND. User can choose and type own name on the Low and High levels.
Also user can choose which type of alarm to be activated – Trap or Email or both
alarms. Digital inputs are not galvanic isolated!
Analog inputs - used for measuring DC voltages. Before using alarm alerts need to
set values in the fields Lower Range and Upper Range. Parameters “Units”,
“Multiplier” and “Offset” can be used to convert measured voltage from any sensor to
meaningful engineering values. Analog inputs are not galvanic isolated!
Use hysteresis value to avoid numerous false alerts (by e-mail or SNMP Trap)
whenever the reading value fluctuates around the threshold !

Local Relay Outpus settings can select whether the local relay to be activated
manually by click button “ON/OFF” or automatic by any of the following parameters:
Digital Input 1
Digital Input 2
Analog input 1
Analog input 2
Sensor 1 Temperature
Sensor 1 Humidity
Sensor 2 Temperature
Sensor 2 Humidity
Sensor 3 Temperature
Sensor 3 Humidity
Sensor 4 Temperature
Sensor 4 Humidity
Sensor 5 Temperature
Sensor 5 Humidity
Any alarm
For every Relay control can be set different time for Pulse duration. The resolution is 0.1
second. By default both relays are activated manualy by web interface of the Status
web page.
Only one parameter can be assigned for relay activation, at the same time.
When the relay is triggered automatically by a parameter then button for manual
operation on the Status page hides.
For loads greater than 3A/30V DC an external relay should be used !

Dynamic DNS
Dynamic DNS service lets you assign a fixed host and domain name to a dynamic
Internet IP address .
SUN-2242 supports Dynamic DNS services from DynDNS and No-IP.
Firmware update
On this web page you can update SUN-2242 with the new firmware.
Please keep in mind not to power off the device during the update! It can damage
