IOTester product package
Includes:
- IOTester box.
- USB cable to PC.
- Power adaptor 100V-240V AC to 5V DC. EU, US, UK connectors. Can also supply small target systems such as display modules.
- 2 x Target test cables. Makes it easy to adapt IOTester to different display connector pin orders.
- Win32, Win64 driver software for XP, Vista, Win7, Win8, Win10
- Full documentation and example PC projects. (Addition: Ready-made IOTester example and PC compilation projects are included with all RAMTEX GUI display driver libraries).
Additional hardware support: FCC/FCB target interface boards
The boards make it easy to create an interface between the IOTester target connectors and display modules with FCC/FCB type connectors.
