digicon Tx1500 - Serial Communication

Torniquete
Tx1500
7.5. Serial communication
Turnstile Tx1500 Duo
's control board allows serial configur
ation of the equipment. The
communication protocol used is as follows:
Where:
- represents beginning of transmission (0x02)STX
- is the byte with the least significant size componentSize(LSB)
- is the byte with the most significant size componentSize(MSB)
- is the information sent to the equipment (one or two bytes);Commands
- is the XOR operation for all bytes sent, from STX to CommandsBCC
The following table shows the enabling commands that can be sent to

FUNCTION
0x48 H
Clears direction from right to left
0x41 A Clears direction from left to right
0x44 D Clears both directions
0x43 C Back to controlling (command used to leave free state)
0x4C L Turnstile free (include free direction <0x4C> + <0x48>)
0x53 S
Direction programming (include direction to be programmed <0x53>
+ <0x48>)

ª
ACK, indicates command OK
0x15 §
NACK, indicates invalid command
0x1A
®
Return command form right to left (RET1)
0x1B
¬
Return command from left to right (RET2)
Free from left to right (1 passage):
0x02 0x02 0x00 0x48 0x48
Configure from left to right as always free:
0x02 0x03 0x00 0x4C 0x48 0x05
Return OK command:
0x02 0x02 0x00 0x06 0x06
ATTENTION:
- Size corresponds to the number of bytes sent (total command
bytes: 1).
- The protocol communication rate is 115,200 bps.
