6.2 - Transmission Protocol - Monitoring
The MicroPlayer MKII can convey several kind of datas onto RS232 port.
- Personalised datas sent by tags [RSxxx] (see chapter "naming of files and folders).
- Command datas of the player sent in " Daisy Chain" mode
- Status datas of the player sent in mode "monitoring" and "advanced monitoring"
To define the kind of sent datas through RS232, 4 monitoring modes exist.
Mode 2 and 3 are defined in the configuration menu (see chapter configuration menu)
The "Daisy Chain " mode and the monitoring mode are added up with the sending information mode
through tags.
Mode 0: no monitoring mode
Only the datas sent through tags [RSxxx] are sent to TX output.
Mode 1: "Daisy Chain"
In this mode, any information received on the Rx line is resent out as received onto the line Tx.
This mode allows to chain up several players the ones after to the others. By connecting Tx output of the
first player to the Rx input of the second player and so on , the information received by the first player
on its Rx socket is resent to the others players in chain. Caution ! if numerous players are connected in
this way, a slight delay can exist on the end of the chain.
