The plug is a right-side positive, keyed and locking 4-pin connector. DE9 RS-232 Connector The RS-232 interface is a male DE9 connector. The BrightSign XDx32 players are DTE devices, similar to a PC. The input to the chip accepts a range between +25V and -25V, so it is compatible with +12V/-12V signaling. The baud rate of the RS-232 interface (which is controlled by system software) is 115200, with no parity, 8 data bits, and 1 stop bit. The RS-232 interface supports RTS/CTS hardware flow control, but no software flow control. The maximum cable length is 50 meters, and the total cable capacitance is 2500pF. Note: A lower capacitance cable allows you to use cable lengths beyond 50 meters. The following diagram illustrates the behavior of the TX and RX signal: 9 All information provided in this reference manual applies to products under development.

This connector is used to allow the player to control external LEDs or other devices requiring 24mA of current or less. Connect the LED outputs to the LED ANODE and connect the LED CATHODE to the ground. If you want to connect another device, then the output is capable of sourcing or sinking up to 3.3V at 24mA, but there is a series resistor of 100Ω in each line. The connector also allows the connecting of external contact closures to the ground. In order to connect a switch, connect one side of the switch to the switch input, and connect the other side to one of the ground pins on the DA15 connector. The connector can also supply 3.3V at up to 500mA to an external device. The 3.3V output is polyfuse-protected and can source up to 500mA. If one BrightSign player is driving the inputs on another BrightSign player, then you can drive at most three inputs from one output. The following calculations explain this limitation: 10 All information provided in this reference manual applies to products under development.

It accepts inputs of up to 1920x1080@60p, with 24-bits RGB. The signaling conforms to the DVI 1.0, HDMI 1.4, and HDCP 1.2 standards. The HDMI signaling has CEC (but no ARC or HEC) 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. 3.5mm IR Out 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 • Ring: IR Input • Sleeve: IR Output Note: The sleeve is used as a ground during input operations. S/PDIF Out The SPDIF_OPT signal is generated within the BCM7421 CPU, which has a direct connection to the S/PDIF port. Wireless BrightSign XDx32 players feature a six-pin connector on top of the printed circuit board (PCB) within the case. This connector allows installation of a peripheral wireless module that supports 802.11 a/b/g/n WiFi protocols. 15 All information provided in this reference manual applies to products under development.

The power supply on the BrightSign XDx32 series is 36W and 12V at 3A. These players will use approximately 1A of power when playing a 720p or 1080i MPEG2 HD source file. An additional 2A of power is available for peripherals connected to the player. The user should not connect any combination of peripherals that will exceed 2A draw. If more than 2A is drawn, the external power supply may shut down due to over-current conditions. The unit will not be damaged, but it may reboot or not operate properly until the overload is removed. If the device is being powered by the power supply, the 2A can be shared in any way among the following connectors: Connector Maximum Power Usage Ethernet Approx. 180mA (when transferring data) USB 500mA (on each connector) DE9 5V 500mA DA15 3.3V 500mA HDMI 5V 500mA IR blaster output 300mA If the device is being powered by PoE, only 1A is available for all connectors (or possibly less if the device is running a resource-intensive presentation). It can be shared in any way among the following connectors: 16 All information provided in this reference manual applies to products under development.

Power Supply There are seven voltage levels present in the player: 12V, 5V, 3.3V, 2.5V, 1.8V, 1.5V, and 1V. Reset BrightSign XDx32 players have a Low Voltage Reset circuit. This circuit will hold the RESET_L signal low until a valid 3.3V power source is present. BCM7434 CPU BrightSign XDx32 players utilize a BCM7434 Multimedia CPU. This CPU runs on 3.3V, 2.5V, and 1V and runs from a 27MHz oscillator. The CPU is reset by the RESET_L signal from the low voltage reset circuit going into the RESET_IN pin on the CPU. When the RESET_IN pin goes from low to high, the BCM7434 will boot from the NAND flash. Built-in Flash The boot code in the BCM7434 instructs it to continue the boot process by reading additional code from the onboard NAND flash, which can be updated in the field, either from a SDHC/SDXC flash card or a USB mass-storage device. Part of the NAND flash is also used to hold non-volatile parameters. The contents of the boot flash are copied into the SDRAM. The CPU then jumps to the boot code. SDRAM BrightSign XDx32 players contain four banks of DDR SDRAM (two 2GB banks and two 4GB banks). When the CPU boots, it will copy the code from the NAND flash device into the SDRAM and then execute the code from the SDRAM. The SDRAM runs at a clock rate of 800MHz, with a data rate of 1600MHz. 18 All information provided in this reference manual applies to products under development. The characteristics and specifications of these products are subject to change without notice. BrightSign assumes no obligation regarding future manufacturing unless otherwise agreed to in writing. © BrightSign LLC, 2015 BrightSign XD232, XD1032, XD1132 Serial Port The XD1032 and XD1132 have a built in UART that communicates with the RS-232 level shifter. The MAX232 uses a capacitive voltage switcher to create valid RS-232 voltage levels for the transmit pin. Video Encoder and Filter The BCM7421 streams decoded video using a single-data rate clock. It also streams the same video out of the on-board DACs. Audio Outputs BrightSign XDx32 players each have a single high quality audio DAC device, which takes in digital audio signals from the CPU in an I2S audio format. The AUD_LRCIN is the framing signal for the audio and runs at the frame rate of the audio source (usually either 44.1KHz or 48KHz). The AUD_BITCLK signal is typically 32 times higher than the AUD_LRCIN. The audio output is fed through an amplifier and sent directly to the audio output jack. It can drive a 32Ω load with a 2V RMS signal. On-Board LEDs There are eight on-board LEDs that indicate the following: LED Indication Green power (Pwr) Displays when the board is powered up and not in reset mode. Green file-system activity Flashes any time there is file-system activity (on any storage device) (Bsy) Green MicroSD activity Displays when a MicroSD card is present. (µSD) Green network activity (Svr) Displays when the player is connected to the BrightSign Network. Green Ethernet activity Flashes when the player is connecting to the network. Displays when connected. 19 All information provided in this reference manual applies to products under development.

Displays when connected. Yellow update (Upd) Flashes when the board is being upgraded. Red status (Err) Flashes a certain number of times to indicate which error is occurring. The flash codes are described below. 2 Unspecified error 3 Network recovery script is preparing to run on a device configured for network recovery. 4 No upgrade file found 5 Failed to load kernel module 6 Board is not capable of running the current firmware version. 7 A piece of on-board hardware is not working correctly 8 Problem related to the storage device (either the USB drive or SD card) 9 Problem related to the registry/NAND 10 The autorun script encountered a load/run error. 11 WiFi-related error (mainly, WiFi not found on USB) 12 Unable to find a bootable image On-Board Switch The on-board switch is connected to the GPIO02. The GPIO02 is pulled low when the service (SVC) button is pressed. Conversely, a pull-up on the button normally sets the GPIO02 to be pulled high. 20 All information provided in this reference manual applies to products under development.

BrightSign assumes no obligation regarding future manufacturing unless otherwise agreed to in writing. © BrightSign LLC, 2015 BrightSign XD232, XD1032, XD1132 Reset Switch/GPIO Button The on-board switch is connected to the reset circuit. Pressing down the reset button will cause the GPIO07 to go low. Holding the reset button low for approximately 10 seconds will cause a hard reset. When the board goes into reset mode, the power LED will be dark until the reset button is released. SDHC/SDXC and MicroSD Slots The XDx32 series has one SDHC/SDXC and one internal MicroSD card slot, both capable of transferring a 25 Mbit/sec video stream, one 5.1 AC3 stream (pass-through), and three stereo PCM tracks simultaneously. There is no inherent limit on the storage capacity of SD cards used for XDx32 players. NAND Flash BrightSign players have a built-in NAND flash. All the code for the player is stored on the NAND flash. It may also be possible to store some content on the NAND flash, which is connected directly to the CPU. Ethernet The 10/100 Base-T Ethernet is implemented on XDx32 players by directly interfacing with the BCM7434. The player has on-board Ethernet magnetics and termination for the RJ-45 cable. USB The USB 2.0 high-speed host controller is implemented internally in the BCM7434 SOC. The board utilizes over-current protected switches that can be used to turn the power to USB devices on or off or to detect over-current situations. 21 All information provided in this reference manual applies to products under development.
