5 - RS232 serial link protocol

The  VP200HDi  can  communicate  with  other  devices  by  receiving    instructions  onto  the  Rx  input  or
transferring  data  through    its  Tx  output.  The  player  complies  with  the  RS232  norm  (see  annex  for
features).
Value by default: 19200 Bauds - 8 bits - no parity - 1 bit start - 1 bit stop

5.1 - Reception Protocol

With the input protocol, the player can receive instructions to launch a folder playback or sets  the volume
control. On the other hand , in a framework of using several players on the same link, the player answers
to its own number ( defined in the file  congig.txt, see chapter related  ) or to a general command

The reception protocol is made of a 3 bytes frame.

      

Byte 1 (statut)           +

     Byte 2 (command)         +             Byte 3 (data)

Reminder:
- a byte is composed of 8 bits: b7 b6 b5 b3 b2 b1 b0
- a binary representation is noted: 10000000b or in hexadecimal : 80h

Byte 1 : Status - 1xxxxxxxb

The byte status is a synchonization information of frame. Its Byte 8 ( b7) is always at 1. All others bytes
( commands or datas )  have their byte 8 to 0.

b7 = 1: refer to a status byte
b6 - b0: identification of the player to be addressed  from 001 to 127 (000001b - 1111111b)

- The address of the player is by default (ID)  001. You can modify it in the configuration file.
- Several players may have the same identification number to create groups.
- Identification 000 is the "overall" code, all players are concerned by the command (unique command for
all the players).
Example:

80h = "overall" code for all the players
81h = player n°001
9Eh = player n° 030
FFh = player n°127

Byte  2  (Command)  0xxxxxxxb  +  Octet  3  (Data)  0xxxxxxxb

The  Byte 2 is a  command and the byte3  is a  data that completes the command byte. A command byte
is always followed by a byte of data. A full frame is therefore made of 3 bytes.

b7 = 0 : refer to a byte of command or data
b6, b5, b4, b3, b2, b1, b0 : command code sent to the player
