Bi-Directional Communication (Response)¶
ListOperationalStates¶
The result of the request from Bi-Directional Communication (Request) channel and ListOperationalStates. The Payload part will contain the list of activated Operational States. Where each byte will be equal to Channel Data Classifier ID.
The Message by Control Protocol (SACP) will have the next structure:
| Part | Field name | Length (bits) | Value |
|---|---|---|---|
| Header | Channel | 2 | 0x03 |
| Data Classifier | 6 | 0x09 | |
| SARP | 16 | Routing Protocol (SARP) address information | |
| ACK | 1 | Acknowledgment flag | |
| TTL | 4 | Time to live | |
| Data length | 11 | 0x1 | |
| Payload | Data | 8 | The Channel Data Classifier ID |
Note
If device has more than one activated Operational State then the
Payload part of Message will have the next sequence of bytes ->
cdcID1, cdcID2, ..., cdcIDN
ConfigurePinMode¶
The result of the request from Bi-Directional Communication (Request) channel and ConfigurePinMode. The Payload part will contain the list of pins that was successfully configured with specified mode.

Note
If you specified more than one Pin using single Message then the
Payload part of Message will have the next sequence of bytes ->
pin1, pin2, ..., pinN
ReadDigitalPin¶
The result of the request from Bi-Directional Communication (Request) channel and
ReadDigitalPin. The Payload part will contain the result from
requested pins. The result value can be as 0x1 (high level) or 0x0

| Data Classifier | 6 | 0x0B | |
| SARP | 16 | Routing Protocol (SARP) address information | |
| ACK | 1 | Acknowledgment flag | |
| TTL | 4 | Time to live | |
| Data length | 11 | 0x1 | |
| Payload | Data | 8 | The value (0x1 or
0x0) |
Note
If you specified more than one Pin using single Message then the
Payload part of Message will have the next sequence of bytes ->
value1, value2, ..., valueN
WriteDigitalPin¶
The result of the request from Bi-Directional Communication (Request) channel and WriteDigitalPin. The Payload part will contain the list of pins that was successfully updated with specified levels.

| Part | Field name | Length (bits) | Value |
|---|---|---|---|
| Header | Channel | 2 | 0x03 |
| Data Classifier | 6 | 0x0C | |
| SARP | 16 | Routing Protocol (SARP) address information | |
| ACK | 1 | Acknowledgment flag | |
| TTL | 4 | Time to live | |
| Data length | 11 | 0x1 | |
| Payload | Data | 8 | The number of the pin |
Note
If you specified more than one Pin using single Message then the
Payload part of Message will have the next sequence of bytes ->
pin1, pin2, ..., pinN
ConfigureAnalogReference¶
The result of the request from Bi-Directional Communication (Request) channel and
ConfigureAnalogReference. The first byte of Payload part will contain 0x01
