"No, not exactly as you described. You have to apply a momentary ground to pin 8 "
If you are already controlling the KPA500 by using the PC serial port you can wake it up by sending P - P Power On The P command will cause the KPA500 to perform internal firmware checks, then execute the main firmware to power up the amplifier. This is the command to use to remotely power up the KPA500. No response is sent from the KPA500 after receiving this command. To turn it off you need the ^ON command: ^ON (Power Status & Off, GET/SET) SET format: ^ON0; turns the KPA500 off. RSP format: ^ONn; where n = 1. No response if off. Note: if a ON; quickly follows a ON0; you _may_ see a ON0; response. See the ‘P’ command in the BootLoader section for a serial command to turn on the KPA500.
