Introduction
The remote plug appears thus:
| Pin | Function |
|---|---|
| 1 | GND |
| 2 | Button |
| 3 | LCD |
| 4 | VCC |
The LCD wire lets the Walkman control the remote's LCD, and the Button wire lets the remote control the Walkman.
The protocol is described in patent US6203344.
Controlling the host device
The host device (Sony Walkman) can be controlled only through the "Button" pin.
When a button is pressed on the remote, a resistance is placed across pin 2 and 4 of the remote connector. Below are the resistance values required to simulate certain keypresses:

| Volume + | 9900 |
| Track Mark | 11900 |
| Play mode | 14300 |
