Firmware-633 Format
The Wi-microDig MIDI implementation uses the following data format for all system exclusive messages:
| Byte | Description |
|---|---|
| 240 (F0h) | System Exclusive Status |
| 125 (7Dh) | Manufacturer ID |
| {DEV} | Device ID |
| {CMD} | Command or Message ID |
| [BODY] | Main Data |
| 247 (F7h) | End of System Exclusive |
Manufacturer ID
The Manufacturer ID identifies the manufacturer of a MIDI device. Infusion Systems uses the number 125 (7Dh). Infusion Systems does not own the manufacturer ID 125 (7Dh). This ID is usually reserved for general educational and/or research equipment. Please ensure that you do not have any devices with manufacturer ID 125 (7Dh) in your MIDI chain.
Device ID
The Device ID identifies a specific Wi-microDig in setups with multiple Wi-microDigs. This setting should remain 0 for use of the Wi-microDig in stand-alone mode. Host mode allows for device IDs other than 0.
Command and Message IDs and [Main Data]
The Command and Message IDs and [Main Data] form the protocol for communication with the Wi-microDig. The protocol consists of commands that are sent to the Wi-microDig and messages that are sent by the Wi-microDig.
