Do BrightSign players support serial control?

Yes, any BrightSign player with a serial port can send and receive commands over serial using a BrightAuthor interactive playlist or custom script. You can use the BrightSign player with controllers like Amx or Crestron. You can also use serial to turn on and off displays and interact with other devices. Visit this FAQ for more details.

Older models have a DE9 serial port, while newer models have a 3.5mm serial port:

  • DE9: 4K1142, 4K1042, XD1132, XD1032, XD1230, HD1022, HD1020, AU320
  • 3.5mm: XT1143, XD1033, HD1023
  • 3.5mm via USB: LS423 (via USB converter cable, available on the BrightSign store)


RS-232 Compatibility

While the DE9 connector is fully RS-232 compatible, the 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). In practice, the serial port can interoperate successfully with the majority of RS-232 receivers, but some devices (including some projectors and Crestron equipment) require strict conformance to RS-232 levels and will not accept 0V as logical 1. In these instances, you can connect the BrightSign player to the serial device using a USB-to-serial cable.
