KB232 PS/2 to RS-232 Keyboard Adapter

The KB232 PS/2 Keyboard RS-232 adapter allows a standard "PC type" PS/2 style keyboard to be connected to an RS-232 port of a computer or other equipment using RS-232 communications. The KB232 can be useful in embedded computing environments when PS/2 or USB ports are not available.

Keys with ASCII equivalents are translated into ASCII characters. This means that standard alphanumeric keys, number keys, and punctuations are translated to their logical equivalents.

The KB232 comes in two version. The standard KB232 has a metalized plastic shell, and the KB232 has a molded shell. The KB232E is a bit more rugged, and is RoHS (lead-free), which allows it to be shipped to Euro markets.

The KB232 adapter can "steal" power from the RS-232 connection to power itself and a low power keyboard. It can also accept either +9 volt or +12 volt power from an external power supply.

Custom keyboard mappings can be loaded to change the ASCII character (or characters) assigned to the keyboard keys. These are stored in non-volatile flash memory.

A kit that includes a full-size PS/2 keyboard and a KB232 adapter is also available. The keyboard in this kit has been determined to be the lowest power full-sized PS/2 keyboard made, and has been tested to work with the KB232 without the need of an external power supply on most desktop PC's.
