This section of the wiki is a sounding board for decoding of the serial protocol, and the verified/agreed upon results posted to protocol.md. Text between question marks indicate unknown, uncertain, or unverified items. Please help determine the purpose of each message, and each byte in each message by posting byte streams and their context in the Examples section.
The internal serial bus is RS-485 at 115200 baud, 8 bits per byte, no parity, 1 stop bit (115200/8-N-1). The plug connector is a Molex 430250400 (or equivalent, see here or here), with the pinout shown below. Wire colors may vary. Connections may be added by connecting to open receptacles on the Main Board, or using Y-splitters. Be sure to keep the wires twisted and/or wrapped to reduce noise injection. It is also recommended to attach pin 3 to the return of the connecting device to reduce common-mode voltage.
| Pin | Signal |
|---|---|
| 1 | RS-485 B (TX+/RX+/D+) |
| 2 | Supply (+12 to 15VDC) |
| 3 | Return (0VDC) |
| 4 | RS-485 A (TX-/RX-/D-) |
| Byte | Name | Description/Values |
|---|---|---|
| 0 | Delimiter | 0x7E |
| 1 | Length | N - 2 (minimum of 5) |
| 2 | Channel | (see Channels) |
| 3 | ?? | 0xAF when Byte 2 is 0xFF, otherwise 0xBF |
| 4 | Type Code | (see Message Types) |
| 5 to N - 2 | Arguments | Optional, usually the same for each message type |
| N - 1 | Checksum | CRC-8 of bytes 1 through N-2, polynomial=0x07, initial=0x02, final XOR=0x02 |
| N | Delimiter | 0x7E |
The protocol uses an addressing scheme to provide direct traffic between devices. Some messages use multicast (broadcast) channels, while others use unicast (point-to-point) channels. Clients should only listen to multicast channels and their own channel, which is assigned my the Main Board. New channel assignments are incremented by one from the previous assignment, except when the assignment reaches 0x3F, the next assignment is 0x30. In addition, the Main Board does not send CTS messages to channels 0x30-0x3F, so these channels are probably not meant to be used. The only known way to "reset" channel assignment is to perform a power cycle.
| Channel(s) | Type | Description |
|---|---|---|
| 0x0A | Unicast | ?Assigned to the Wifi Module? |
| 0x0C | Unicast | ?? |
| 0x10-0x2F | Unicast | Assigned to clients, Main Board provides CTS |
| 0x30-0x3F | ?Unicast? | Assigned to clients, Main Board does not provide CTS |
| 0xFE | Multicast | Used by Main Board and clients for channel assignment |
| 0xFF | Multicast | Used by Main Board for broadcasting to all clients |
Clients are essentially devices on the RS-485 bus other than the Main Board, such as Top Side Panels, WiFi Modules, or the App.

A New Client Clear to Send message is sent by the Main Board at 10 Hz during start up and 1 Hz otherwise. This message is for flow control (prevents collisions on the RS-485 bus), as it indicates it is safe for a client to send a Channel Assignment Request. It is unclear how multiple clients avoid collisions.
Type Code: 0x00
Length: 5
A Channel Assignment Request is sent by a (new) client that has not been assigned a channel, immediately after a New Client Clear to Send message is received.
Type Code: 0x01
Length: 8
Arguments:
| Byte | Values/Description |
|---|---|
| 0 | ?Device Type? 0x02=?Top Side Panel? |
| 1 | ?? |

Examples:
08 FE BF 01 02 76 57 (SpaTouch1 connected before power-on)
08 FE BF 01 02 F2 47 (TP900 connected before power-on)
08 FE BF 01 02 F1 73 (TP900 connected after power-on)
A Channel Assignment Response is sent by the Main Board after a Channel Assignment Request. Depending on the arguments of the request, the response may include a new channel, or re-use an existing channel, though the details of this are unclear.
Type Code: 0x02
Length: 8
Arguments:
| Byte | Values/Description |
|---|---|
| 0 | Channel |
| 1 | 0xF1=??, 0xF2=?? |
| 2 | 0x47=??,0x93=?? |
Examples:
08 FE BF 10 76 57 (Request arguments are 0x02, 0x76, 0x57)
08 FE BF 10 F2 47 (Request arguments are 0x02, 0xF2, 0x47)
08 FE BF 11 F1 93 (Request arguments are 0x02, 0xF1, 0x73)
A Clear to Send message is sent by the Main Board at 60 Hz, unless it is sending another message. This message is for flow control (prevents collisions on the RS-485 bus), as indicates it is safe for a client to send a message. Therefore, a client should only send messages immediately after detecting a Clear to Send message with its assigned channel.
Type Code: 0x06
