4.8. 

UART transmission (RS232, RS422, RS485 or similar)

4.8.1. 

Bit transmission layer (physical layer)

A full or half-duplex connection such as RS232, RS422 or RS485 is used for the physical layer.

4.8.2. 

Data link layer

Transmission is in frames and blocks. A block comprises a maximum of 256 frames. A frame comprises a 

maximum of 256 bytes, of which a maximum of 250 bytes can be user data. The result is a maximum block size of  

64000 bytes of user data.
The data link layer is used to safeguard the data between sender and recipient. The sender receives a response 

from the recipient for each frame received. If the sender does not receive a response from the recipient within a 

time window of 350 milliseconds after sending a frame, the frame sent is repeated until the error counter signals  

the cancellation of the transmission.

4.8.2.1. 

Structure of a frame

5A LL SS FF DD ... DD P1 P2

5A: 

Start code for synchronisation

LL: 

Number of bytes in the frame not including the start code

SS: 

Status byte

FF: 

Frame number

DD: 

User data

P1: 

16-bit checksum low byte

P2: 

16-bit checksum high byte

4.8.2.2. 

Start code and synchronisation

The start code is used to synchronise the recipient to the sender. It further allows the receiver to synchronise to the  

start of a frame when no data have been received for 15 milliseconds.

4.8.2.3. 

Status byte

The status byte has the following significance:

50: 

Data packet

A0: 

Response: “OK”

A1: 

Response: “Memory error” (the receiver was unable to allocate any memory for the data block received)

A response is only 3 bytes long and is not CRC checked.

“OK” response: 5A 02 A0

“Memory error” response: 5A 02 A1
