How to install this program step by step?

Unzip the zip file to disk

Connect Zed Bull device with the USB cable

Star EXE list all COM port and Click Start automatic search Zed Bull hardware and create file ZEDBULL.COMPORT

If exist ZEDBULL.COMPORT file and hardware opened okay then no automatic comport search panel

Exe work Read 4D chip; ZEDBULL display RESP data to manual mode edit program RESP textbox

If no exist pg4 data after TPX cloner pg4 read manual mode (COPY 4D; TPX Cloner; …..) pg4 to manual mode edit program PG4 textbox

Pg4 name edit and Click ADD TO DATABASE

All project reload enabled okay

In case of problems emergency exit -> Right Mouse but

Q&A for you reference:

Q: I have Mini Zed Bull clone but without RJ45 connecter. Does your program work with my zed bull?

A: RJ45 connecter. That’s no problem.

Option1. Right point can be incorporated within MAX232 chip 4 pieces of capacitor.

Connect point 1. GND2. + 5V 3.RxD 4.RxD to Max232 and to RS232 1.RxD 2.TxD 3 GND 4 optional +12V If TPX cloner hardware tape hack.

Option2. Or hack2 no need max232. Zed bull to RS232 connected GND RDX TXD logic0 0Volt Logic1 +5V

Then work TPX cloner, 2 pin build to free RS232 pin.

This 2 version

  1. Serial comport mode -9V +9V communication
  2. Direct mode without voltage driver chip
