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 10/100/1000 base t operation is supported 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 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 gpio the xc2055 and xc4055 have a 12 pin gpio switch and led connector, which allows the player to control external leds or other devices the port can supply 3 3v\@300ma to pwr pins (available in rev g and higher) and sink or source 24ma on each button pin auxiliary power is 1a the gpio port is a standard design manufactured by phoenix contact, wurth electronics, and others pluggable gpio terminal blocks can be inserted into the gpio connector to make bare wire contacts (see here https //www digikey com/short/3101mw for an example part) these terminal blocks can be purchased from the brightsign store https //www brightsign biz/digital signage products/accessories/gpio terminal block if you wish to source your own terminal blocks, make sure to use 4 pin or 6 pin blocks (12 pin blocks are extremely difficult to remove from the gpio port) 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 gpio also allows for 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 gpio connector 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 the gpio outputs have 100ω series resistors; the gpio inputs have 1k pullup resistors to 3 3v; and the input threshold is 2v high and 8v low the high voltage is not problematic, but the low voltage can be if there are too many inputs connected to one output 1 out driving 1 in v=3 3 100/(100+1,000)=0 3 1 out driving 2 in v=3 3 100/(100+500)=0 55 1 out driving 3 in v=3 3 100/(100+333 3)=0 76 1 out driving 4 in v=3 3 100/(100+250)= 94 (this is too high, so 1 output driving 3 inputs is the maximum) gpio pinout the following table illustrates the pinout of the gpio on the xc5 pin primary secondary tertiary 1 gnd 2 3 3v pwr 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 the following schematic illustrates the pinout of the gpio connector 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 serial the xc5 contains an uart (asynchronous serial) interface it is a 3 5mm (⅛") jack that connects a serial modem or other devices that use a serial connector, and it uses ttl for communication this 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 this 3 5mm serial port has the following configuration (from the perspective of the player) tip receive ring transmit 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 audio connector the xc2055 and xc4055 have a 3 5mm analog audio jack the analog audio connector has the following pinout tip left audio ring right audio sleeve ground for audio signal 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 wifi & antennas the xc2055 and xc4055 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 microsd card / ssd 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 d4 drives may fit but have not been tested
