Title: Interface ASCII to USB
Post by: Walt on September 24, 2010, 04:44:05 am

I have a test equipment. The access is only via a external USB ASCII keyboard (computer keyboard) connected at the USB keyboard connector of the test equipment.

I would like to send ASCII strings from a computer (test sequences) via USB Keyboard input of the test equipment instead of manual keyboard entries.
Is a solution available for such a application?
I have no access to the software of the test equipment, so I would like to simulate the ASCII keyboard with a computer.

Thank you for your help
Walt

There is no such thing as an ASCII USB keyboard. Keyboards do not send characters, they send keycodes, what characters are generated from this depends on the operating system and the language (localisation) you are using.

I am sure what you want to do (emulate keyboard input into your test system) is readily available, probably as a combination of hardware and software that would run on your PC.

I just did a quick Google on "usb keyboard emulation" and saw tons of possible solutions; you could easily narrow down search results.
