Inspired by “
Ford 1710 Rear Remote Valve“
Wanted to have rear-hydraulics for a log-splitter and maybe other tools. I chose to add a simple ‘changeover’ valve. By default hydraulic pressure is going to the 3-point hitch, when energizing the solenoid valve hydraulic pressure is sent to the log-splitter. The log-splitter has it’s own manual control valve.

Connecting to ABB B23 Modbus energymeter.
I have the USB-RS485 plugged into a Debian Linux pc system (x86_64). I used the ModPoll tool from
modbusdriver.com for basic connection testing. #./modpoll /dev/ttyUSB0 -b 9600 -p none -m rtu -a 1 -r 23296 -t 4:int -c 6
Offset addres 23296 (or hex 0x5B00) should have L1-N voltage.
Read 6 next values also (-c 6)
Gave me L-to-N and L-to-L voltages.
Wrote a small C application to poll every second and write to MariaDB/MySQL database table. Should be possible to recompile for Raspberry-PI (ARM) to.
Uses libmodbus(-dev) and libmariadbclient(-dev).
First switching power supply working.
I have an ARM board to be powered, which draws between 0.5 and 1.5 ampere’s on 5 volt. Tried using an standard 7805 (2 ampere spec), but the system would not boot. VOut dropped to 4.5 volts and 7805 was getting to hot with +/- 24 volt VIn.
So i made an circuit based on the LM2576T-5.
L1: Inductor 100uH
Recoverd from PC PSU
5.0 Amps Schottky Barrier Rectifier
C1: 470uF 35v
Reused from other project
C2: 3300uF 10v
Also recovered from PC PSU
F1: Fuse holder and 400mA
Stock, price n/a
Input voltage is an battery+solar power supply that varies between 23-24 to 29 volts.
Working power supply (left) with active load.
Bad output: (spikes)
What happens if an normal (or to slow) diode is used:
Yellow is regulator V-OUT.
Blue line represents voltage output for load (feedback signal).
Borrowed lm2576 library for
Eagle PCB Design from eaglecentral.ca | LM2576 circuit
Capture inverter data yourself? Or want to process generated data? Instead of using the Omnik Portal App?
I found out that it is possible to configure the wifi kit to send TCP/UDP packets to an remote server. After that i started googling around. With some minimal data i started write a small C program.
Some other related project on the internet:
GitHub – Woutrrr / Omnik-Data-Logger | Language: Python | Found first
GitHub – micromys / Omnik | Language: PHP
GitHub – arjenv / omnikstatus | Language: C | Found after completing my own script 🙁
Those scripts are polling the inverter each few minutes. When my research started, i found out, by configuring the web interface, that Omnik also offers the possibility to push TCP or UDP packets to an specified server. With this enabled i started testing en developing.
Reading the message (which byte means what?) was based on the GitHub projects. So someone else did the hard work 😉
Getting started… (read on)

The ReadyNAS Pro 6 has an serial port at RS232 level.
First tried to connect with an USB to TTL adapter. No luck. After some more reading and searching on the internet i just tried to connect with an USB to RS232 adapter. With positive results!
Counting from the USB ports:
1 – GND (pin 5 on RS232 /
DB9 adapter) 2 – TX (RX / pin 2 on RS232 /
DB9 adapter) 3 – RX (TX / pin 3 on RS232 /
Use PuTTY or Minicom and configure it with: 9600n8.
Hookup an USB keyboard to the ReadyNAS. (i use an usb port on the backside)
Power On the ReadyNAS, see PuTTY of Minicom showing the device booting up ! 🙂 (printscreen follows)
With the USB keyboard you can hit F3 and enter the BIOS.
Screen information will by sent to PuTTY or Minicom.
Note, there is also an VGA pin header on the main board. I will try that later, because i have to order some parts. (SUB-D 15 female for an flatcable, and an 16 pin flatcable connector)
Please have a look at these sites to:
ReadyNAS Pro 6 – Serial pin out
ReadyNAS Pro 6 – Breakout board – NIC, USB, COM
ReadyNAS Pro 6 – COM Pin header
