Volume folder setting
The name of the folder can act on the output volume. This function is used to broadcast messages loud
more or less than others files.
The increase or decrease of the volume by the volume tags is always done relatively the main volume.
The xx parameter of the tag [V+xx] and [V-xx] is the number of volume steps to increase or decrease the
main volume. It is always written with 2 digits (example: 01, 32, 64). It is between 00 and 64.
Example :
001[V+05]: increase the volume level from 5 steps during the folder playback
001[V-03] : decrease the volume level form 3 steps during the folder playback
At the end of the reading of the folder, the volume level goes back to its previous level.
- If the variation values exceed the minimum or maximum values of the player, the levels are settled to
their maximum or minimum.
●
[NT]
-
This option defines the interruption mode of the folder currently read.
If this option is registered in the folder name, the read file cannot be interrupted and instructions received
are ignored.
Without this option, the reading of the currently read folder can be interrupted at any time by an
external action. (input, RS232 ...)
Example:
001 [NT] - The folder can NOT be interrupted.
In that case, an action on one of the input contacts, through RS232 or other is ignored and the reading of
the current file is not stopped. Caution! The action is not memorised and the triggering information is lost.
Note: the [NT] tag work exclusively on the change folder commands. The PLAY, STOP, NEXT FILE or
PREVIOUS FILE commands are immediately executed.
●
[RSxxx] –
This tag allows to send bytes onto the RS232 output.
When the folder is called, a list of bytes is transferred by the serial link in order to control other devices
(another player, switching grid, projector, ..) The bytes to send are included in a text file that will be
especially created for.
Value by default : 19200 Bauds - 8 bits – no parity – 1 bit start – 1 bit stop
(modifiable through the config.txt file)
The xxx parameter of the tag [RSxxx] is the number of serial command to send (number of the line in the
«serial.txt» file). It is always written with 3 digits (example: 001, 045, 999). It is between 001 and 999.
The file definition of the bytes to send must be named : serial.txt
This file will be copied at the root of the media ( memory card/flash drive)
This file is a text file (raw text without page setting ) that can be created with any easy text editor like
«notepad» from windows or similar. When saving, use «ANSI» coding. Do not use special characters.
The file «serial.txt» of RS232 codes is a text file containing one or several lines. Each of these lines will
include a sequence of bytes expressed in hexadecimal and separated by a space ( from 00h to FFh). You
must only indicate the two characters of the wished hexadecimal value.
