Data Field U.K.
Besides the SID, the Data Field shall also contain other parameters: a transfer request parameter (TRTP) and Counter bytes.
[F1If the data to be handled is larger than the available space in one message, it will be split in several submessages. Each submessage shall have the same Header and SID, but will contain a 2-bytes counter, Counter Current (CC) and Counter Max (CM), to indicate the submessage number. To enable error checking and abort the receiving device acknowledges every submessage. The receiving device can accept the submessage, ask for it to be re-transmitted, request the sending device to start again or abort the transmission.]
Textual Amendments
If not used, CC and CM shall be given the value 0xFF.
For instance, the following message
| HEADER | SID | TRTP | CC | CM | DATA | CS |
|---|---|---|---|---|---|---|
| 3 bytes | Longer than 255 bytes | 1 byte | ||||
Shall be transmitted as such:
| HEADER | SID | TRTP | 01 | n | DATA | CS |
|---|---|---|---|---|---|---|
| 3 bytes | 255 bytes | 1 byte | ||||
| HEADER | SID | TRTP | 02 | n | DATA | CS |
|---|---|---|---|---|---|---|
| 3 bytes | 255 bytes | 1 byte | ||||
…
| HEADER | SID | TRTP | N | N | DATA | CS |
|---|---|---|---|---|---|---|
| 3 bytes | Max. 255 bytes | 1 byte | ||||
Table 3 contains the messages the VU and the ITS Unit shall be able to exchange. The content of each parameter is given in hexadecimal. Aren't represented in the table CC and CM for clarity, see above for complete format.
