What am I supposed to deal with???
Hi all, Can anyone tell me what I have? It's a black box, a little larger than a credit card (7cm wide by 12cm long, 2.5cm tall at the front and 5cm tall at the back (think a wedge shape)). On the top it has a red and a green LED and a port (0.5cm wide by 1.5cm long). On the back it has a standard PS2 port and a 9V 20mA dc connector. On the bottom all it says is that it's a KB69273. Inside, the circuit board says it is an RU board (CP10 94V-0) and has A207454AB printed on the board. The last bit of identification is a RoHS sticker which reads C2818577. Any help would be gratefully accepted!
I considered a security logging feature or something similar. I didn’t think about a remote connection for a device. Thanks.
It seems to be a PS2 connector, possibly for both signals and power. Opening it up might help you understand its function through the components.
It's an MSP430 chip paired with an RS232 interface, making this application tailored. I think it's probably a safety feature for a machine—perhaps a key insertion triggers the MCU to confirm with a clear "OK" response, while the LEDs indicate status that might not always be directly useful.
