{{% controller-page "sotp031201" %}}
This controller has one handle with several notch cartridges (P4/B7, P4/B2-B7, P5/B5, P5/B7, B5/B8, P13/B7), a D-Pad and 7 buttons (Select, Start, A, B, C, D, ATS). The A button can distinguish between "soft" and "hard" presses. In addition, the controller has four lamps.
Internally, it is a vendor-specific class device. The USB descriptors and the reported data change depending on the notch cartridge inserted.

P5/B5 cartridge
When this cartridge is inserted, the controller emulates the Train Mascon. The buttons are mapped 1:1 except the D button, which is mapped to the Close (閉) button.
The lamps are used as follows, from top to bottom: doors, ATS, 45 and 15.
P5/B8 cartridge
When this cartridge is inserted, the controller emulates the Two handle controller "Type 2". The buttons are mapped 1:1 and ATS is mapped to START. The reverser is mapped to the D-pad UP and DOWN buttons.
Only the top lamp is used, for the doors.
P4/B7, P4/B2-B7, P5/B7, P13/B7 cartridges
When any of these cartridges is inserted, the controller functions similarly to the P5/B5 mode and data changes depending on the amount of notches. The specific cartridge in use can be detected by looking at the bcdDevice value from the standard USB descriptor:
| P4/B7 | P4/B2-B7 | P5/B7 | P13/B7 |
|---|---|---|---|
| 0x0300 | 0x0400 | 0x0800 | 0x0A00 |
Input
The controller sends reports to the host (PS2) formed by 4 bytes:
| Byte 1 | Byte 2 | Byte 3 | Byte 4 |
|---|---|---|---|
| 0x01 | Reverser+handle | Buttons 1 | Buttons 2 |
The reverser+handle byte combines two values representing the state of the reverser and the power/brake handle. The handle notch is represented sequentially starting from 0x1 (Emergency), brake notches from highest to lowest, N and power notches from lowest to highest.
| Forward | Neutral | Backwards |
|---|---|---|
| 0x8X | 0x0X | 0x4X |
Note: the P5/B7 and P13/B7 cartridges do not make use of the reverser and use both nibbles for the handle notch.
The first button byte uses six bits to represent the state of the physical buttons. 0 means that the button is released and 1 that it is pressed. A bitmask can be used to retrieve the buttons.
| Bit 0 | Bit 1 | Bit 2 | Bit 3 | Bit 4 | Bit 5 |
|---|---|---|---|---|---|
| ATS | D | A (soft) | A (hard) | B | C |
The second button byte also uses six bits to represent the state of the physical buttons.
| Bit 0 | Bit 1 | Bit 2 | Bit 3 | Bit 4 | Bit 5 |
|---|---|---|---|---|---|
| START | SELECT | UP | DOWN | LEFT | RIGHT |
Output
The controller supports receiving data via a control transfer to turn on/off the lamps. The setup packet is as follows:
| bmRequestType | bRequest | wValue | wIndex | wLength |
|---|---|---|---|---|
| 0x40 | 0x50 | Lamp data | 0x0000 | 0x0000 |
Changing wValue controls the lamps with the logic below.
- Door lamp: 0x0X is Off, 0x1X is On.
- Signal lamp: 0xX0 is Off, 0xX1 is ATS, 0xX2 is 45, 0xX3 is 15.
