◇ Instructions for connecting amplifier and computer ( RS485 ):
Hardware preparation ：
a 、 Recommended configuration of computer: Windows XP and above, Windows 10
recommended.Display resolution greater than 1366 x 768 ；
b 、 USB-RS485 adapter: it is recommended to adopt the USB to serial port scheme of CH340,
485half duplex communication; and correctly install the USB to serial port driver; (the
following figure shows the common adapter, only connect two wires a and B to the RJ45
port of power amplifier)
c 、 Adapter to RJ45 port of power amplifier: Category 5 line and above.
◇ Online steps ：
a 、 Connect the hardware as shown in the figure below ：
Connection precautions:
I 、 In order to ensure the normal communication, the RJ45 port at the end of the bus needs
to be equipped with a 120ohm impedance matcher;
II
、 The line sequence of USB-RS485 adapter and RJ45 port of power amplifier shall be the
same, RJ45 Pin1 = 485 A, RJ45 Pin2 = 485 B;
b
、 The 485 address and baud rate of the machine can be set through the front panel rotary
