10.2 Transmission Protocol - Monitoring
The ChronoPlayer can send several kinds of data onto the RS-232 port.
•
Custom data sent by the [RSxxx] tags (see the chapter Control of the ChronoPlayer with the Folders
and the Files).
•
Command data of the player sent in “Daisy Chain” mode.
•
Status data of the player sent in the “Monitoring” and “Advanced Monitoring” modes.
To define the kind of data sent through RS-232, 4 monitoring modes exist.
The monitoring mode is defined in the configuration file
config.txt
(see the chapter Configuration File).
The “Daisy Chain”, “Monitoring” and “Advanced Monitoring” modes operate besides the [RSxxx] tags.
•
Mode 0: No monitoring
Only the data from the [RSxxx] tags is sent onto the 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 one after another. By connecting the 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 input is resent to the others players in a chain.

Caution! If numerous players are connected in this way, a slight delay can exist at the end of the
chain.
