OPERATING MANUAL
DPH5005 Digital Power Supply Upper Computer
(For Win7 and above)
1 Communication Board Connetion
1.1 Wire Communication Board Connection
Open data package, double click CH341SER.EXE and install drive
program of communication board.
After installation, please use the attach cable to connect
digital power supply with communication board, and use USB cable to
connect Micro UBB port with PC.
Digital power supply communication data setting:
Keep pressing ↑button to power on, then enter into data setting
interface. Press ↑or↓ to choose data, then press knob to adjust the
value. After adjustment, press twice shortly SET key to exist data
setting, and those data are stored automatically.
COMM: Communication stitch setting, ON represents opening
communication, OFF represents closing communication.
ADDR: Digital power supply address code, range 001-255.
BAUD: Communication baud rate, 2400,4800,9600,19200 adjusting.
BPIN: Bluetooth PIN Code Pairing, 0000-9999, useless for wire
communication.

1.2 Bluetooth communication board
Bluetooth communication board is Bluetooth 2.0 protocol. Please
use the attached cable to connect digital power supply with
bluetooth communication board. After power on, the LED on the
board will blink; so the bluetooth is in the state of searching.
Now open the PC bluetooth and right click bluetooth icon to add
device. Laptop can use its own blue teeth, and desktop can use the
attached USB bluetooth adapter. When you insert the adapter into
desktop, the driver will be installed automatically, and there
will be bluetooth icon on desk state bar.

After searching, the bluetooth device will show and the last 3 bit
001 of name represent address code of digital power supply.
When connect bluetooth device, please enter pairing code, the
default password is 1234.

After connecting, the system will download and install Virtual
serial port driver of bluetooth automatically. The smaller number
CMO is what we use, eg COM3, we need to choose COM3 on upper
computer.
If we need to adjust communication data, the operation is similar
as wire communication.
Note:
1, The power supply voltage of communication interface is DC 3.3V and power supply
ability is limit. Don’t connect other big power bluetooth or WIFI module, otherwise it
will be burnt.
2, when using the bluetooth communication function, if power off for digital power
supply, you need to choose COM interface to connect bluetooth module again after
power on.
3, If the LED on bluetooth module is blinking, it shows it is on the state of
disconnection. If LED is lighting, it shows it is on the state of connection
4, When using bluetooth function, don’t put bluetooth module in the metal box,
otherwise it will affect signal strength.
5, When changing communication data of digital power supply, you must disconnect
bluetooth with PC, the LED will be blinking. Otherwise you can change the data of
bluetooth board.
6, For computer operating system, please install official version. if you install pirated
or lite operating system, there may be a lack of bluetooth virtual serial port driver on
those operating system, and the system can’t assign COM port to bluetooth board.
And it can’t communicate with the upper computer.
2.Instal the upper computer software
Open data package, unzip upper computer software.
Hangzhou Ruideng Technology Co., Ltd.
Double click setup.exe and install upper computer software.
Select installation directory, and click next.
Click next to install, and wait installation to complete.

3 Software operating
Double click short-cut icon on the desk to open upper computer
software.
After opening software, select serial port, baud rate and slave address, and cli
ck online to communicate. After online, all the button of digital power supply are locked
automatically; click “open” to open output of digital power supply. Basic function contai
ns voltage and current setting, quick call out and brightness adjustment function. Advanc
ed function contains data group reads and writes, automatic test, voltage scan and current scan
function.

DPH5005 CNC Power Communication Protocol V1.2
Communication protocol overview:
The communication protocol for this device is specifically MODBUS RTU. This can be used via RS232, RS485 or
Bluetooth serial interface.
Note, This product only supports MODBUS RTU Function Codes 0x03 (03H), 0x06 (06H), 0x10 (10H)
II. Communication protocol described:
Message transmission is asynchronous, Modbus-RTU is in 11-bit bytes.
(For a full description of the general MODBUS RTU Protocol see http://modbus.org/docs/PI_MBUS_300.pdf)
Modbus is a generic protocol. The implementation of the location and function of registers is specific to the
designer of this device however the format of the command structure for the Modbus Communication is fixed and
as detailed in the above referenced document. Below is a brief introduction to the Standard Modbus RTU
protocol and the registers and Modbus RTU Function Codes used in this specific device.

Before sending data, the bus silent period (no data transmition time) is more than 3.5 character, (eg: Baud rate is
9600, the time is 5ms).
RTU messages start with a silent interval of at least 3.5 character time periods.Following the last transmitted
character, a similar interval of at least 3.5 character times marks the end of the message. A new message can
begin after this interval.
The entire message frame must be transmitted as a continuous stream. If a silent interval of more than 3.5
character times occurs before completion of the frame, the receiving device flushes the incomplete message and
assumes that the next byte will be the address field of a new message.
Similarly, if a new message begins earlier than 3.5 character times following a previous message, then the
receiving device will consider it to be a continuation of the previous message. This will set an error, as the value
in the final CRC field will not be valid for the combined messages.
1.1 Address Field:
The address field of a message frame contains eight bits, from 1 to 255. This byte shows the slaver of setting
address by user will receive the message form main. Every slaver must have unique address field, and only the
salver fits the address field, it can respond loopback message. When slaver send the message back, the
loopback data will begin with its own address filed. The address field sent by the main is the address filed the
salver received, and the loopback address filed is the loopback slaver filed address. The corresponding address
filed show where it come from.
1.2 Function Field:
The Function Code field tells the addressed slave what function to perform. This device only supports the
functions 0x03 0x06 0x10.
Function code

Operations (binary)
0x03
Read Holding Register

0x06
Write single register
Writes binary data to a single register.
0x10
