The Pro-160 display adaptor board allows the LCD from the Pro-160 to be mounted separately from the controller itself for more convenient viewing. It also has a keypad to make profile changes possible without needing to access the controller itself.
The LCD can also be mounted separately from the adaptor board as here.
The adaptor board is supplied with 2 x 1m leads, but longer leads are available.
Versions are available with and without a spare LCD.
