The description of the format is as follows.
Name | Descriptions |
SOF | Start of Frame. Always set or receive the value as “02H” |
|
|
Device Code | This indicates the destination of communication. |
| Set “000000” when accessing the camera’s function settings |
| Set “100000” when accessing the camera’s extended function settings. |
| Please refer to the “Camera Command List” and “Description of the Camera Control |
| Commands”. |
Read / Write | This specifies “Read” or “Write” to command numbers. |
| Set (or receive) “0” to send the read command. |
| Set (or receive) “1” to send the write command. |
|
|
Page | This specifies page selection (access selection to registers or EEPROM) of command. |
Selection |
|
| Set “0” to access the command register of the camera. |
| Read command: To obtain the current data from the command register. |
| Write command: To set a data into the command register. |
| The previously stored data is replaced by this data. However, the data in the EEPROM is not |
| replaced. |
| Set ”1” to access the EEPROM of the camera. |
| Read command: To read stored data from the EEPROM. |
| Write command: To store data into the EEPROM as default value. |
| The camera returns the receiving code “01H” to the PC after storing data in the EEPROM. |
|
|
Command | This indicates the contents of the data sent or received. Refer to the following page for the |
Code | details. |
|
|
Data Length | This indicates the data length (unit: byte). |
| Receiving Frame: |
| The data length is dependent on each read command sent. |
| The data length is defined as “00H” when sending the write command. |
| The data length of error response is defined as “00H”. |
| Sending frame: |
| The data length is 1 byte dummy data when sending the read command, and that data is |
| not referenced. |
| The data length is dependent on each “write command” sent. |
|
|
Data | This indicates write data or read data according to command type. |
|
|
EOF | End of Frame. Always set or receive the value as “03H” |
|
|
Receiving | This indicates results of the command sent |
Code |
|
| 01H: OK (ACK), 10H: NG (NAC), 12H: Command number error (Not matching), |
| 13H: Communication frame error (only for Gamma data upload), |
| 14H: Time out error (Two seconds), |
| 15H: Check sum error (only for Gamma data upload), |
| 16H: Data length error (Not matching), 17H: EEPROM write error |
