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 and audio 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:
Pin | Primary | Secondary | Tertiary |
|---|---|---|---|
1 | GND |

3 | Button0 | UART1_RXD |
|
4 | Button1 | I.R_IN |
|
5 | Button2 | SPDIF1_OUT |
|
6 | Button3 | PWM |
|
7 | GND |
|
|
8 | 3.3V PWR |
|
|
9 | Button4 | UART0_RXD | I2C_SCL |
10 | Button5 | UART0_TXD | I2C_SDA |
11 | Button6 | UART1_TXD |
|
12 | Button7 | I.R_OUT |

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
The sleeve is used as a ground during input operations. |
: 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 a combination analog/optical audio jack. 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. Dolby audio is supported as a paid license.
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.
