9.4 Monitoring of the Player through the RS-232 Serial Link -
#RS_MONITORING:x
The ChronoPlayer has one serial input and one serial output complying with the RS-232 standard. This link
can be used to control the player but also to monitor him.
Four configurations are possible to define the kind of outgoing link.
Mode 0: No monitoring. No data is sent by the player.
•
Mode 1: "Daisy Chain" mode. This mode allows to chain up the players one after another with only
•
one RS-232 link. The Tx serial output of a player is connected to the Rx serial input of the next one
and so on. When the first player receives an instruction, this same instruction is sent to its output and
so on. Caution! When numerous players are chained up, a latency period can exist at the end of the
chain.
Mode 2: "Monitoring" mode. In this mode, the player sends some information about its status onto its
•
Tx serial output (see the chapter RS-232 Serial Link Protocol - Transmission Protocol - Monitoring).
An external device can therefore receive information to know if the player is playing or stopped.
These functions can be used to check the good functioning of the player.
Mode 3: "Advanced monitoring" mode. Besides the functions of the standard monitoring mode, the
•
advanced mode regularly sends information about the player status. A frame is sent or not every
250 ms depending on the status of the player among 3 possibilities:
1. Stopped - A frame indicating that the player does not play and is waiting for a command is sent.
2. Playing - A frame indicating that the player is playing a file is sent.
3. Other - No frame is sent: The player is not available. The memory card is defective or missing,
power supply default, the player is out of order, etc.
This mode is used in a context of security message management. A faulty frame reports an error and
allows to take corrective action.
