If the player loses the network connection, it will attempt to reconnect until the connection is re-established. If a player loses connection while a presentation is displayed, it will continue to display the presentation until new content is downloaded. If a player is downloading content when the connection is lost, it will resume downloading once the connection is re-established.

When using BrightAuthor:connected the playerthe player's status is status is accessible in the Network tab. The player's status is displayed to the immediate left of the Player ID in All Devices, or within the group where the device is assigned to. Player status is only available for devices connected to the internet.

If a player loses power, it will automatically start playing your content, presentation, or custom script when it powers up again. If there is a presentation script (autorun.brs) on a storage device, the unit will start the presentation from the beginning. If there is no presentation script present on the storage device(s), a unit will play alphabetically any content it finds in the root of the storage.

Any BrightSign player with a serial port can send and receive commands over serial using BrightAuthor:connected/BrightAuthor or a custom script (for example, to turn displays on or off and interact with devices with controllers such as Crestron, Alcorn or AMX).

Newer player models have a 3.5mm serial port, older models have a DE-9/DB-9 serial port:

• 3.5mm: XC4055, XC2055, XD1035, XT1145, XT2145, XT1144, XD1034, HD1025, HD1024, XT1143, XD1033, HD1023

• 3.5mm via USB: LS425, LS424, LS423 (via USB converter cable, available on the BrightSign store)

• DE-9/DB-9: 4K1142, 4K1042, XD1132, XD1032, XD1230, HD1022, HD1020, AU320. The DE-9/DB-9 connector is fully RS-232 compatible but the 3.5mm serial transmit pin does not comply with voltage levels for RS-232 signaling (which requires a voltage below -3V for logical 1). The serial port can interoperate successfully with most RS-232 receivers, but some devices (including some projectors and Crestron equipment) will not accept 0V as logical 1. In these instances, you can connect the player to the serial device using a USB-to-serial cable.
