As long as UNOcentral is connected to a power supply, the system will begin to operate.
Through the HDMI connection on the back of UNOcentral, UNOcentral's screen can be output
to displays with HDMI interfaces, such as computer monitors and TVs. UNOcentral is managed
through a web GUI. Users can remotely manage UNOcentral through the browsers of other
hosts, or directly output UNOcentral to a display and use a USB keyboard and mouse for man-
agement. To use UNOcentral remote management or other network services, it is recommend-
ed to connect the network cable to the LAN1 port on the back of UNOcentral (The MAC address
of LAN1 is provided on the UNOcentral’s label). As shown in Figure 1
If RS485 communication interface is used between UNOcentral and UNOnext, they must be
used Daisy-Chain, and the communication mode is Modbus/RTU protocol. It is recommend-
ed to use 22AWG multi-core shielded twisted pair cable or above to achieve the best re-
sults. The simple wiring instructions is below, please use the RS485 adapter include in the
box (Please plug-in on the COM1 of the UNOcentral).

UNOnext can directly connect to a controller with RS485 interface, up to 16 devices can be connect-
ed to one controller.
If the UART sengs of UNOnext have been modied, please modify to the default sengs
above before connecng to UNOcentral.
The Modbus slave address of UNOnext can be set by dip switch following below table. Oth-
ers detail UNOnext sengs can be referred the UNOnext user manual. Table 2 Set Modbus slave

7. Connect the HDMI cable, mouse, and keyboard to the screen to confirm that the number of
UNOnext is the same as the number and sensor data are shown on the screen.
If the sensor data does not show value at all or the number of devices is incorrect, please
check below checklists
◇Are all UNOnext power on?
◇Is RS485 wiring problem?
◇Do use the wrong pin hole?
◇Does follow RS485 installation guideline?
◇All of UNOnext should be used different modbus slave address.
