The modes are defined in the configuration file (see related chapter)
Note : The different transmission modes are not compatible with the Show Control mode sending serial
command included in the sequence file. If a sequence file is read, the serial link is desactivated. To
prevent any conflict, we suggest to desactivated the transmission mode in the menu option.
Mode 1 : "Daisy Chain" (default mode)
In this mode, any information received on the Rx line is sent out as received on the line Tx. Several
EventPlayers can be linked by connecting the Tx output of the first one onto the Rx input of the next one
and so on... Data received by the first player on Rx are sent out on Tx and received on the Rx input of
the next player in the chain. Note: if a large number of players are connected this way, a slight delay may
occur at the end of the chain.
Mode 2 : "Surveillance"
In these Surveillance modes, the player is sending status report information onto its Tx output; for each
change of status, the player is sending the related information onto the Tx output. It is not possible to link
up several players. The data can then be processed and analysed by a controller, computer, security
device.
The transmission protocol, as the reception protocol, is made of a 3 byte frame.
Byte 1 : Statut
> b7 = 1 : indicates the status byte
> b6 - b0 : identification of the sending player from 001 to 127 (000001b - 1111111b)
The default address (ID) is 001. Setup in the Option menu.
Byte 2 (Command)
Unique value: 00000000b (00h).
The command code is 0000b, the other bits are reserved and have the 0 value.
Byte 3 (Data)
00000000b (00h) :

USB mode, insert of a memory card...
00000001b (01h) :
