The XD235 and XD1035 support HDR video, video rotation at 2160x3840x60p, and at least two simultaneous 1920x1080x60p decodes.
USB
The XD1035 has one USB-A and one USB-C port to connect USB-compatible devices. The USB-C port supports both device and host mode and USB-C to any GP800-C device. Both ports meet USB 2.0 specifications.
The XD235 does not support USB ports.
Ethernet
A single RJ45 jack is provided for connection that supports 10base-T, 100base-T, and 1000base-T operations, as well as Power over Ethernet (PoE).
...
LS425 has full HD HDMI® output and the LS445 has a UHD/4K HDMI output. The LS425 is capable of outputting HD video (up to a maximum video resolution of 2048x1048x60p), while the LS445 can output 4K video resolutions (including 1920x1200x60p, and up to 3840x2160x60p)
Power Connector
The power connector for the LS425 and LS445, which connects the power cord to the device, is rated for 12V@1.5A. The connector is used for power input only—it does not transfer data.

port. To transmit a digital audio signal, use a TOSLINK optical audio cable with a 3.5mm connector. Analog and digital audio cannot be transmitted simultaneously.
The full-scale voltage output of the analog audio is 2V RMS. The minimum load impedance is 32Ω.
The analog audio connector has the following pinout:

The sleeve is used as a ground during input operations.
3.5mm Serial
The XD1035 has a UART (asynchronous serial) interface in a 3.5 mm mini-jack that uses RS-232 levels for communication. The receiver will tolerate input voltages between -30V and +30V, with anything below 3V interpreted as a logical 1. The transmitter drives +8V for logical 0 and -8V for logical 1.
The default baud rate of the interface is 115200, with no parity, 8 data bits, and 1 stop bit. These settings can be configured in the software. The serial interface supports TX, RX, and ground only—RTS/CTS hardware flow control is not supported. The following diagram illustrates the behavior of the TX and RX signal:
The 3.5mm serial port has the following configuration (from the perspective of the player):
- Tip: Receive
- Ring: Transmit
- Sleeve: Ground
BrightSign players are DCE devices, so communication with another DCE device that uses a 3.5mm port would require a null-modem cable or converter that transposes the TX/RX signals. If the device communicating with the player is a DTE device with a DE9 serial port (performing asynchronous transmission), the serial cable should be wired as shown in the following diagram:
GPIO
The XD235 and XD1035 have a 12-pin GPIO switch and an LED connector, which allows the player to control external LEDs or other devices. The port can supply 5V@1Amp to PWR pins and sink or source 24mA on each button pin. Auxiliary power is 1A.
WiFi Antenna Connectors
...
output is via USB-C.
USB-C
A USB-C 3.0 port connects to USB-compatible devices. The USB-C port supports both device and host mode, and supports custom cable solutions such as USB-C to GPIO cable, USB-C to USB-A and 3.5 serial cable, and USB-C to IR.
WiFi & Antennas
The LS425 and LS445 models come equipped with an M.2 connector slot and two SMT-mounted SMA connectors. The M.2 slot supports M.2 PCIe cards for WiFi and Bluetooth connectivity (sold separately), while the SMA connectors facilitate the connection of external antennas.
