This section describes the characteristics and operation of all connectors on the XD235 and XD1035.
Power Connector
The power connector for the XD235 and XD1035, which connects the power cord to the device, is rated for 12V @3A. The plug is a right-side positive, locking 2-pin (1x2) connector.
HDMI Output
The HDMI-out connector is used to send digital video and audio to HDMI-enabled sink devices. The HDMI® output on the XD235 and XD1035 is HDMI 2.0a. CEC control is supported over the HDMI interface independently. This connector can output a maximum video resolution of 3840x2160x60p.
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).
This ethernet connection delivers power on PoE Type 1 at up to 12.95W and as PoE Type 2 (PoE+) at up to 25.5W to the XD235 and/or XD1035 units.
3.5mm Audio Connector
The XD235 and XD1035 have a combination 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.
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:
XT245, XT1145, XT2145, and CV-UHD3.
Ethernet
This connection is used to connect an ethernet cable for internet access. The XT245, XT1145, XT2145, and CV-UHD3 wired ethernet connection is capable of 10/100/1000 Mbps.
HDMI Input
The HDMI-in connector is used to receive digital video and audio from HDMI-enabled source devices. This connector on all XT5 and CV-UHD3 devices is capable of accepting a maximum video resolution of 4096x2160x60p. HDMI input is not available on the XT245.
The HDMI signaling has CEC functionality. The CEC channel is electrically coupled to the corresponding signal on the HDMI output, and the CEC commands will pass through the player even when it does not have power.
HDMI Output
The HDMI-out connector is used to send digital video and audio to HDMI-enabled sink devices. The XT245, XT1145 and CV-UHD3 have an HDMI output and the XT2145 has two HDMI outputs. The HDMI output is capable of HDMI 2.1, and one of the HDMI outputs on the XT2145 is HDMI 2.1.
CEC control and AVI are supported over each HDMI interface independently, and it can maintain the configured multiscreen layout if one of the HDMI outputs loses sync.
Power Connector
The power connector for the XT245, XT1145, XT2145, and CV-UHD3, which connects the power cord to the device, is rated for 12V 3A. It uses a locking connector to prevent inadvertent disconnections.
GPIO
The XT245, XT1145, XT2145, and CV-UHD3 have a 12-pin GPIO switch and an LED connector, which allows the player to control external LEDs or other devices requiring 24mA of current or less. The port can supply 3.3V@500mA to PWR pins.
3.5mm IR Input/Output
The IR blaster generates or receives a space-encoded NEC or Pronto Hex signal. 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: 3.3V@50mA
- Ring: IR Input
- Sleeve: IR Output
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:
USB
The XT245 does not have a USB port.
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 3.3V@300mA to PWR pins and sink or source 24mA on each button pin. Auxiliary power is 1A.
WiFi Antenna Connectors
The XD235 and XD1035 have two SMA connectors XT1145, XT2145, and CV-UHD3 have one USB-A 2.0 and one USB-C port to connect USB-compatible devices. The USB-C port supports both device and host mode, and BrightSign USB accessories (for example, the USB-C to GPIO Panda device).
3.5mm Audio Connector
The XT245, XT1145, XT2145, and CV-UHD3 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. EAC3 and AC3 are also supported.
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:
- Tip: Left audio
- Ring: Right audio
- Sleeve: Ground for audio signal
WiFi Antenna Connectors
The XT245, XT1145, XT2145, and CV-UHD3 have a two SMT type SMA connectors and an M.2 connector to allow easy installation of external WiFi antennas. . Both devices contain an internal M.2 PCIe card that enables WiFi/Bluetooth.
