6.3 Connecting USB
The methods to connect the USB communication cable are as follows:
Insert one end of the USB communication cable to the USB port (see Figure 1-3) on the rear panel of the UPS and
connect the other end to the USB port of the computer. After the connection, you need to install the USB drive
program in the installation disk.
6.4 Connecting Serial Port Communication Cables
The methods to connect the serial port communication cable are as follows:
Insert one end of the DB9 serial port communication cable to the DB9 serial port (see port 5 in Figure 1-3) on the rear
panel of the UPS, and connect the other end to the DB9 port of the computer.
The pin function of DB9 is listed below:
6.5 Connecting Control Port
The control port adopts the standard RJ45 port, which supports the Modbus/Jbus port and connects the Vertiv
temperature/temperature & humidity sensor.
The user can select Modbus/Jbus protocol function or sensor function via the 'Settings' on the LCD.
6.6 Connecting Built-In Ethrenet Port
The built-in Ethernet port supports the HTTP protocol. The user can connect one end of the net cable to the Ethernet
port of the UPS and connect the other end to the built-in Ethernet port of the computer. The user can remotely access
the UPS via the IE, Chrome and Firefox, so as to monitor the UPS in real time.
Connect net cables: Connect one end of the net cable to the Ethernet port of the UPS and connect the other end to the
built-in Ethernet port (or the switch port, Router port) of the computer.
Set network parameters: The user should change the parameters (IP address, subnet mask, gateway address) of the
computer or the UPS, so as to make the computer communicate the UPS well.
To change the network parameters of the UPS, operate them via the 'Settings'->’Monitor’, as shown in Figure 6-4.
