There are two proprietary connectors - the "E-Monitor stand connector", which looks like a slightly

miniaturised 9-pin D-type socket and the "docking connector", which has 144 pins. As the

functionality of the E-Monitor stand is extremely basic, the primary purpose of this connector appears

to be the transmission of DC power.

The author has not managed to locate any freely available public available documentation about the

PR02X internals or pin-outs of the proprietary connectors and therefore, in order to understand how

it works, the first step is to disassemble to facilitate analysis.
