Instruction Sheet
Warning
9Please read this instruction carefully before use.
9Switch off the power before wiring.
9DVP04AD-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of
airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance
staff from operating the device (e.g. key or specific tools are required to open the enclosure) in case
danger and damage on the device may occur.
9DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may
occur. Check all the wiring again before switching on the power.
9DO NOT touch any terminal when the power is switched on. DO NOT touch any internal circuit in 1
minute after the power is switched off.
9Make sure the groud terminal is correctly grounded in order to prevent electromagnetic
interference.

DVP-EH2 MPU program, DVP04AD-H2 is able to read and write the data in the module. There are 49 16-bit
control registers (CR) in DVP04AD-H2.
The user can select voltage or current output by wiring. Range of voltage output: ±10VDC (resolution: 1.25mV).
Range of current output: ±20mA (resolution: 5μA).

LSB (Least Significant Bit): For voltage input 1LSB = 10V/8,000 = 1.25mV。
For current input 1LSB = 20mA/4,000 = 5μA。
Explanations:
1. CR#0: Model name. The user can read the model name from the program and see if the extension module
exists.
2. CR#1: The working mode of the two channels in the analog output module. There are 4 modes for each channel
which can be set up separately. For example, if the user needs to set up CH1: mode 2 (b2 ~ b0 = 010) and CH2:
mode 1 (b5 ~ b3 = 001), CR#1 has to be set as H000A and the higher bits (b12 ~ b15) have to be reserved.
Default value = H’0000.

3. CR#2 ~ CR#5: The settings of average times of the signals at CH1 ~ CH4. Range: K1 ~ K20 (default = K10).
Please note that the average time settings at CR#2 ~ CR#5 only need to be written in once.
4. CR#6 ~ CR#9: The average of the signals at CH1 ~ CH4 obtained from the settings in CR#2 ~ CR#5. For
example, if the settings in CR#2 ~ CR#5 is 10, the content in CR#6 ~ CR#9 will be the average of the most
recent 10 signals at CH1 ~ CH4.
CR#10, CR#11, CR#16, CR#17, CR#22, CR#23, CR#28 and CR#29 are reserved.
5. CR#12 ~ CR#15: The present value of input signals at CH1 ~ CH4.
6. CR#18 ~ CR#21: The adjusted OFFSET value of CH1 ~ CH4, representing the analog input voltage or current
when the analog signal is converted into digital value 0.
The adjustable range of voltage: -5V ~ +5V (-4,000LSB ~ +4,000LSB)
The adjustable range of current: -20mA ~ +20mA (-4,000LSB ~ +4,000LSB)
7. CR#24 ~ CR#27: The adjusted GAIN value of CH1 ~ CH4, representing the analog input voltage or current when
the analog signal is converted into digital value 4,000.
The adjustable range of voltage: -4V ~ +20V (-3,200LSB ~ +16,000LSB)
The adjustable range of current: -16mA ~ +52mA (-3,200LSB ~ +10,400LSB)
Please note that: GAIN value – OFFSET value = +800LSB ~ +12,000LSB (voltage) or +800LSB ~ +6,400LSB (current)
When GAIN – OFFSET is small (steep oblique), the resolution of input signal will be finer and variation on the
digital value will be greater. When GAIN – OFFSET is big (gradual oblique), the resolution of input signal will be
rougher and variation on the digital value will be smaller.

9. CR#31: The setting of RS-485 communication address (Range: 01 ~ 255, default = K1).
10. CR#32: The setting of RS-485 communication speed. b0: 4,800bps; b1: 9,600bps (default); b2: 19,200bps; b3:
38,400bps; b4: 57,600bps; b5: 115,200bps; b6 ~ b13: reserved; b14: high/low bit exchange of CRC checksum
(only valid in RTU mode); b15 = 0: ASCII mode; b15 = 1: RTU mode. ASCII data format: 7-bit, Even bit, 1 stop
bit (7, E, 1); RTU data format: 8-bit, Even bit, 1 stop bit (8, E, 1).
11. CR#33: For authorizations on some internal functions, e.g. OFFSET/GAIN tuning. The latched function will
store the output setting in the internal memory before the power is cut off.
12. CR#34: Firmware version of the model.
13. CR#35 ~ CR#48: Parameters for system use.
14. CR#0 ~ CR#34: The corresponding parameter addresses H’4032 ~ H’4022 are for users to read/write data by
RS-485 communication. When using RS-485, the user has to separate the module with MPU first.
a. Communication baud rate: 4,800/9,600/19,200/38,400/57,600/115,200bps
b. Modbus ASCII/RTU communication protocols: ASCII data format (7-bit, Even bit, 1 stop bit (7, E, 1)); RTU
data format (8-bit, Even bit, 1 stop bit (8, E, 1)).
c. Function: H’03 (read register data); H’06 (write 1 word datum to register); H’10 (write many word data to
register)
d. Latched CR should be written by RS-485 communication to stay latched. CR will not be latched if written by
MPU through TO/DTO instruction.

5μA.

Trial Operation & Troubleshooting
LED Display
1. When the module is powered for the first time, POWER LED will be on and ERROR LED will be on for 0.5
second. After this, A/D LED will start to flash.
2. When the power supply is normal, POWER LED will be on and ERROR LED should be off. When the
power supply is less than 19.5V, ERROR LED will keep being on until the power supply is higher than
19.5V.
3. When controlled by RS-485, the RS-485 LED on the module will flash after receiving the RS-485
instruction.
4. When the input or output value exceeds the upper bound or falls below the lower bound after conversion,
ERROR LED will flash.

1. When M1083 = Off, during the execution of FROM/TO instruction, all external or internal
interruption subroutines will be forbidden. The interruptions are allowed only after FROM/TO
instruction finishes its execution. FROM/TO instruction can also be used in an interruption
subroutine.
2. When M1083 = On and an interruption signal occurs during the execution of FROM/TO
instruction, the interruption will be processed first (with a 100us delay) and the execution of
FROM/TO will be stopped. After the interruption subroutine finishes its execution, the
program will jump to the next instructio of FROM/TO. FROM/TO cannot be used in an
interruption subroutine.
