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).

The BrightSign App allows you to send predefined UDP messages to players through an iPhone or iPad. It works on any player with ethernet or wireless. See this link for details.

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.

See Serial Port Configurationfor more information.

Do BrightSign players support storage hot swapping?

Yes, SD and USB storage devices are detected as soon as they're plugged in. So, if you plug in a USB stick with a firmware update, then the player will try to install it immediately upon detection. 

Note that removing a storage device will unmount the file system for that drive until the device is rebooted. This means that you cannot, for example, remove an SD card and then insert one containing a new presentation to switch playback--the player will need to be rebooted for the new content to play.
