UC-7112-LX Plus - User Guide 8
„Connect to gateway“ window with a list of available devices will be displayed. Select required device and fill
username, password then click on “Connect” button. For connection you need to be in the same subnet as UC-
7112 device. In case if your device is in different subnet, you should adjust LAN parameters.
Note: Host address can be written manually in case device was not detected. This problem could be caused by
firewall for instance.
IMPORTANT: Default Username is „admin “. Default Password is „rw“. Default IP address for
LAN1: 192.168.3.127 and for LAN2: 192.168.4.127
Note: In case of connection failure see Troubleshooting (page 17).

communication with PV inverters (Hybrid application)
In Gateway tab fill information about project. Especially name and version are important to fill. The name will
be visible during detection of gateways.
Note: Port P1 is determined for connecting InteliSys Hybrid controller only. Port P2 and Port ETH1 can be used
for connecting e.g. PV inverters. In case of predefined configuration, the P1 port can be used with different
device.
Add Device from list by click on button „ Add device” in ETH1 or P2 tab.

UC-7112-LX Plus - User Guide 11
Set Device address and set constants. If the device is connected via ETH1, the IP address needs to be set.

This chapter describes typical usage of UC-7112-LX Plus communication gateway module.
4.1 Communication with PV inverters
With proper configuration UC-7112-LX Plus can manage communication with photovoltaic (PV) inverters and
share this data to InteliSysNTC Hybrid controller. Configuration can be crated by selecting devices from list, as
described in chapter Creating configuration.
If there are used more PV inverters, the UC-7112-LX Plus will calculate totals from all kind of available values,
eg.: sum of all active powers, sum of all reactive powers...
Note: Available communication for PV inverter is Modbus RTU (RS485, RS422 or RS232) or Modbus TCP
(Ethernet).
Note: If you didn’t find your PV inverter in list of supported inverters, contact your local distributor or ComAp
technical support
4.1.1 Settings InteliSysNTC Hybrid
InteliSysNTC Hybrid needs to be configured properly to establish connection with UC-7112-LX Plus. RS485(2)
port is dedicated for connection UC-7112-LX Plus
Recommended settings:
Setpoints - Comms settings Value
RS232(2) mode MODBUS-DIRECT
RS232(2)MBCSpd 57600 bps
Contr. address 32
Controlles address and baudrate must match settings from Port P1.

UC-7112-LX Plus - User Guide 16
4.2 Communication with 3rd party devices
UC-7112-LX Plus can be a communication gateway between 3rd party devices and ComAp WebSupervisor.
UC-7112-LX Plus obtains data from Modbus 3rd party device and transfers this data to the WebSupervisor.
Communication channel is ethernet connection with RJ45 connector.
For registration the unit at WebSupervisor it is needed to get AirGate ID, Controller address and access code.
AirGate ID see Getting AirGate ID on page 14
Default access code 0
Default Controller address 1
Note: This feature is available at WebSupervisor Pro paid version.
Note: If you didn’t find your 3rd party device in list of supported devices, contact your local distributor or ComAp
technical support
4.3 Communication with MTU MIP4000
UC-7112-LX Plus enabling the connection between MTU MIP4000 engine controller and ComAp controller. For

5 Troubleshooting
5.1 Device is not detectable via ComAp Communication Gateway Configurator 17
5.2 InteliSys NTC Hybrid displays "WrnConCommErr" 17
5.3 Not possible to connect 17
5.4 Getting data for technical support 18
6back to Table of contents
5.1 Device is not detectable via ComAp
Communication Gateway Configurator
Check the setting of IP address. Module's IP address should be in the same range as computer's IP
address. Default IP address of module is 192.168.3.127 with mask 255.255.255.0 for LAN1 port. And
192.168.4.127 for LAN2 port. LAN settings can be changed even if the device is in different sub-network.
Check the firewall setting in your computer. For detecting the device are used UDP broadcast packets. If
the problem remains try to start computer in emergency mode - but have in mind that the computer is not
secured by firewall in that time, so it is recommended to disconnect computer from the internet.
Check the wiring. It is recommended to use direct cross wired cable between computer and UC-7112-LX
Plus
Check the status of "Ready" LED. The LED should flash with 2 seconds period.
5.2 InteliSys NTC Hybrid displays
"WrnConCommErr"
In case that UC-7112-LX Plus is used for communication with PV inverters the alarm message
"WrnConCommErr" can be displayed if the communication between UC-7112-LX Plus and InteliSys NTC
Hybrid is not successfully established.
This message appears every time when the system is started and is active for tens of seconds.
Check wiring and settings see Settings InteliSysNTC Hybrid on page 15
Check if TX LED at UC-7112-LX Plus is flashing. If TX is flashing and RX not it means that InteliSys NTC
Hybrid is not responding and the wrong setting is at InteliSys NTC Hybrid. If the TX LED is not flashing the
configuration in UC-7112-LX Plus is not correct, please make sure UC-7112-LX Plus has configuration
related to PV inverters.
5.3 Not possible to connect
In case you can detect the device, but attempt for connecting is not successful, try to check network settings.
To change network settings computer don’t needs to be in the same sub-network as UC-7112-LX Plus, but for
connection computer have to be in the same sub-network.

UC-7112-LX Plus - User Guide 18
If the UC-7112-LX Plus is connected into network with DHCP server (most of office networks), you can try to
set UC-7112-LX Plus to obtain IP address automatically.
After Download is completed, check Use DHCP option and click on “Upload Settings” button.
5.4 Getting data for technical support
You can get “support file” by clicking on “Diagnostics” button in the upper bar of ComAp Communication
Gateway Configurator 2 and then “Save Support file”. This file could be useful for troubleshooting with ComAp
