=== Формат заголовка пакета ===
e Header of a Packet consists of 3 bytes: two synchronization [SYNC] bytes (0xAA 0xAA), followed

by a [PLENGTH] (Payload length) byte:
{| class="wikitable"
|+Заголовок пакета
!байт синхронизации
!байт синхронизации
!байт длины пакета
|}
e two [SYNC] bytes are used to signal the beginning of a new arriving Packet and are bytes with

the value 0xAA (decimal 170). Synchronization is two bytes long, instead of only one, to reduce the

chance that [SYNC] (0xAA) bytes occurring within the Packet could be mistaken for the beginning

of a Packet. Although it is still possible for two consecutive [SYNC] bytes to appear within a Packet

(leading to a parser attempting to begin parsing the middle of a Packet as the beginning of a Packet) the

[PLENGTH] and [CHKSUM] combined ensure that such a "mis-sync'd Packet" will never be accidentally

interpreted as a valid packet (see Payload Checksum below for more details).

e [PLENGTH] byte indicates the length, in bytes, of the Packet's Data Payload [PAYLOAD…] section,

and may be any value from 0 up to 169. Any higher value indicates an error (PLENGTH TOO LARGE).

Be sure to note that [PLENGTH] is the length of the Packet's Data Payload, NOT of the entire Packet.

e Packet's complete length will always be [PLENGTH] + 4.
