INTRODUCTION 1
Network Module MB-GATEWAY is used to connect EXHAUSTO air handling units to the computer network
(Ethernet). Module functions:
• TCP/IP Modbus gateway
• IPV4 protocol
• WEB server
• FTP server
• Building of Modbus commands using HTTP requests
• Authorized connection
• Automatic data communication between Modbus units
• Updating of the module rmware using MicroSD memory card (the update can be loaded using
FTP client as well)
• RT clock
• Galvanically insulated RS485 communication line
If the network module is not installed factory, you may install it as an option. To do this you need an ins-
tallation kit consisting of:
1. MB-GATEWAY module with 4GB MicroSD memory card;
2. Sticker with a MAC address and elds for writing down connection settings
3. UTP cable (0.5 m)
4. RS485 communication cable with RJ11 plugs (2 m)
5. Adapter
6. Installation Manual
EN
1 and 2 – power supply connection (e.g. from another (standalone)
power supply). 12 V DC/ AC to 25 V DC/AC supply voltage is used,
power supply should be at least 2 W. Polarity of the power supply
terminals is not important.
3 – GND of RS485 communication line
4 – D0 (-) of RS485 communication line
5 – D1 (+) of RS485 communication line
Note: Communication line is galvanically insulated from the power
supply.
External PS – power supply with AC/DC adapter (included).
Ethernet RJ45 – network adapter connector.
RS485 RJ11 – RS485 communication line connector.

The module can be installed in any convenient for user place (mounting rail is recommended), where
the following conditions are ensured:
• ambient temperature -20 ... 70 °C
• relative humidity 30% ... 85% (without condensation);
• protection against vertical falling water drops (IP 20).
If you are going to use some MB-GATEWAYs in the same LAN, you need to change their IP addresses. LAN
cannot have more than one unit using the same IP address, thus for conguring of the MB-GATEWAY you
need to connect it directly to the PC.
Step-by-step conguration:
1 Apply static TCP/IP settings for the network interface card in the PC that will be used to connect the
unit. These settings depend on the OS used, see the OS documentation:
• IP address should begin with 192.168.0 and end with number 1 to 254 except 51, for example:
192.168.0.11
• Subnet mask: 255.255.255.0.
2 Connect the power supply (included).
3 Connect the MB-GATEWAY to the properly congured PC using UTP (RJ45) cable (included). If the
connection does not work (the PC does not support Auto MDI-X), connect the PC and MB-GATEWAY to
the switch.
4 Enter the MB-GATEWAY IP address (the default one is 192.168.0.51) into the browser (Google Chro-
me is recommended) address bar.
5 Each page is password protected. When you open the conguration page, you will be asked to en-
ter user name and password. Default user name is “admin”, password – “admin”. We recommend to change
password for security. If you forget your login details you can restore the parameters to factory default
settings (see “Restoring factory defaults”).
6 If you performed the above steps properly, the MB-GATEWAY conguration page opens. Here you
can select the language, set IP address, Modbus (RS485) baudrate, Modbus (RS485) parity, date and time,
change user name and password, page theme, open the help le, air hand¬ling unit controller’s WEB
page.
If you cannot connect to the device (have forgotten the password, IP address etc.), you always can restore
the factory defaults. Steps of restoring the factory defaults:
1 Turn o the power supply.
2 Open the top ap.
3 Holding down the button turn on the power supply.
4 When you release the button, the factory defaults are restored (note: you will need to re-enter set-
tings).
Step-by-step rmware update:
1 Download (http://salda.lt/lt/products/category/products/) the update FIRMWARE.BIN and save to
the MicroSD root directory:
a. if you update using FTP client, you do not need to turn o the power supply;
2.5 Updating of the rmware using MicroSD card
2.4 Restoring factory defaults

5
2
b. If you save the le to the MicroSD card that is removed from the module, turn o the module power
supply before inserting the card back. When you have the card inserted, turn the power supply on.
2 If there is a proper le, the module will start the update procedure. Every ~1 second RJ45 LEDs are
ashing in an alternating way. Do not turn o the power supply until the process is not nished.
3 In ~2 min. the module will nish the update and restart to the normal state.
4 When the update is nished, the le FIRMWARE.BIN is automatically deleted.
Indications of the RJ45 connector LEDs:
• Both LED indicators ashes slowly and synchronously – MB-GATEWAY has no rmware installed.
• LED indicators ashes slowly in an alternating way – the rmware is being updated.
• LED indicators are o – no power supply and/or connection to the Ethernet.
2.6 FTP server
This module has the built-in FTP server too, so you do not need to remove the MicroSD memory card to
access and edit the data on it. FTP server has the same connection data as the protected WEB pages. For
the FTP client software use the “Passive Mode” setting.
