XC5 Hardware Interfaces

This section describes the characteristics and operation of all connectors on the XC2055 and XC4055.

Ethernet 

A single RJ45 jack is provided for connection to a local network conforming to IEEE 802.3 at up to 1000Mbps full duplex. 10base-T, 100base-TX and 1000base-T operation is supported.

HDMI Output

The HDMI^®-out connector is used to send digital video to HDMI-enabled sink devices. XC2055 has two HDMI outputs and the XC4055 has four HDMI outputs. One of the HDMI outputs on each device type is HDMI 2.1. CEC control is  supported over each HDMI interface independently, and it can maintain the configured multiscreen layout if one of the HDMI outputs loses sync.

The XC2055 connector can output a maximum video resolution of 7680x4320x60p, decoding up to 8-bit.

The XC4055 connector can output a maximum video resolution of 7680x4320x60p, decoding up to 10-bit

The XC2055 and XC4055 support HDR10 video, HLG, video rotation at 2160x3840x60p, and at least four 3840x2160x60p decodes simultaneously.

Power Connector

The power connector for the XC2055 and XC4055, which connects the power cord to the device, is rated for 19V. It uses a locking connector to prevent inadvertent disconnections.

GPIO 

The XC2055 and XC4055 have a 12-pin GPIO switch and LED connector. The port can supply 3.3V@1Amp to PWR pins and sink or source 24mA on each button pin. Auxiliary power is 1A.

The GPIO connector functions are: 

3.5mm IR Input/Output

The IR blaster can transmit and receive a variety of common Consumer-IR formats including NEC and RC5. RC5 encoding is also supported. The two transported bit values of the signal (0 and 1) are encoded using differing lengths of low-time IR pulses.

The 3.5mm IR in/out port has the following pinout:

• Tip: 3V@50mA

• Ring: IR Input

• Sleeve: IR Output

• : Receive

• Sleeve: Ground

3.5mm Serial

The UART interface has a 3.5mm (⅛") jack for connection of external devices that use a standard asynchronous serial protocol. It uses TTL for communication. The 3.5mm serial connector has a driver/receiver which converts TIA/RS-232-F voltage levels for the processor. The port is tolerant up to ±30-V inputs.

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: Transmit

• Ring: Receive

• Sleeve: Ground

BrightSign players are DTE devices, so communication with another DTE 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 uses a DE9 serial port, the serial cable should be wired as shown in the following diagram:

USB

The XC2055 and XC4055 have one USB-A and one USB-C 3.0 port to connect USB-compatible devices.

These devices provide 5V 1A over each USB port for peripheral devices.

3.5mm Audio Connector

The XC2055 and XC4055 have an analog audio jack.

The analog audio connector has the following pinout:

• Tip: Left audio

• Ring: Right audio

• Sleeve: Ground for audio signal

WiFi Antenna Connectors

The XC2055 and XC4055 have two SMA connectors to allow easy installation of external WiFi antennas.

SD card / SSD Interface

The µSD card supports UHS-1 SDR-104.

The SSD interface is NVMe, PCIe 3.0 4x.

XC5 players will accept NVMe SSDs in M.2 2242 or 2280 (but not 2260) form factors of SX id type (single-sided form factor). Double-sided drives (DX id type)* will not fit because the back side of the SSD is essentially flush against the motherboard. For example, a 2280-S1 module will fit a BrightSign player but a 2280-D2 module would not.

NVMe drives with heat sinks are not compatible with our players.
