AT506-3W-123 has ten FIFO message buffers, the related features for the return
message is to inform user the buffer is full or buffer empty, as below :
1) Buffer full: The maximum display buffer size is 10 records. When the buffer of
AT506-3W-123 is full and still send 11
th
data to it, then the original first
data will be dropped out automatically and meanwhile AT506-3W-123 will
send one message back to inform this situation.
Sub-command = 64H, please refer 4.4.10.
Data(0) = 02H, Mean the AT506-3W-123’s buffer is full
2) Buffer empty: When the stored messages in buffer keep to be confirmed back till the
last one is confirmed back, at this moment, AT506-3W-123 will send
one message back to inform this “buffer empty” situation.
Sub-command = 64H, please refer 4.4.10.
Data(0) = 03H, Mean the AT506-3W-123’s buffer is empty
4.5.4 Protocol for AT530/AT730
The RS-232 communication mode of RS232 Converter is fixed to be as follows :
Baud Rate 9600 bps
Parity None
Data Length 8 bits
Stop Bits 1 bit
4.5.4.1 Configure the data receiving block time interval.
