2.2 Communication Wiring
By default, its address is 1, and the DIP switches are in the off state.
The host computer software can use the default address 1 to
communicate with the device (or broadcast address 254, which is only
applicable when one device is mounted on the network).

2.3 DO Wiring
The relay is single-pole, double-throw, and each circuit has three terminals, one
group is normally ON and the other is normally OFF (normally ON contacts are
generally used), and the terminal identification is subject to the indications on the
film.

3 Parameters and Working Mode Configuration
3.1 Device and PC Connection Settings
The USB end of the USB to RS485/RS232 converter is directly connected to the
USB port of computer, and 485/232 end is wired according to the wiring method in
"Chapter 2.2 Communication Wiring".
Serial port number query method: Open "My Computer - Device Manager - Port
(COM and LPT)" and the COM number that appears after the USB to 485/232
device is inserted is the serial port number.
3.2 Device Address
3.2.1 Introduction
The Offset Address of this device is 1 by default, and the broadcast address is
254 to communicate, but 0 cannot be used.
Communication address = Hardware address (DIP switch address) + Offset
address.
The device’s Factory default settings of communication address is 1.
With DIP switch, users can quickly modify the device address.
（1）The address is "31" when all 5 dial codes are dialed above;
（2）The address is "0" When all t5 dial codes are dialed below;
（3）The leftmost 1 is the lowest digit in binary;；
（4）DIP address table:

3.2.1 Device Communication Address Reading
After the device is connected normally, click "read address" on the serial relay
debugging software to read the current address of the device [only support
broadcast read address when there is one device on the bus].
3.2.2 Software Address Setting and Reading
Click "Read" or "Set" to read or set the software address of the device (address
parameters stored in the device).

（1）The Modbus device command supports the following Modbus addresses:
00001 to 09999 are discrete outputs (coils)
10001 to 19999 are discrete inputs (contacts)
30001 to 39999 are input registers (usually analog inputs)
40001 to 49999 are holding registers (usually store device configuration information)
In 5-bit code format, the first character determines register type, and the remaining 4
characters represent address.
Address 1 starts from 0, such as 00001 corresponds to 0000.

The bit 8 of the data of register 30009 is the same as the data of register 00001.
The same is true for the optocoupler input. Bit8 and bit9 of register 30003 and
registers 10001 and 10002 all correspond to the specified hardware.
The register address is in accordance with the PLC naming rules, the real address is
to remove the highest bit, and then subtract 1
