power connector the power connector for the xdx32 series is rated for 12v @ 3a the plug is a right side positive, keyed and locking 4 pin connector de 9 rs 232 connector the rs 232 interface is a male de 9 (more commonly referred to as db 9) 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 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 the following table illustrates the pinout of the de9 serial connector on the xdx32 series pin description pin description 1 nc 2 receive data into the player 3 transmit data out of the player 4 available 5v\@500ma 5 ground 6 nc 7 nc 8 nc 9 nc da15 switch / led connector the switch/led connector is a da15 female 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 the gpio outputs have 100ω series resistors; the gpio inputs have 1k pullup resistors to 3 3v; and the input threshold on the 541 chips 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) the following table illustrates the pinout of the da15 on the xdx32 series of players pin description pin description 1 ir blaster input 2 ground 3 button 6 i/o 4 button 5 i/o 5 button 3 i/o 6 ground 7 button 1 i/o 8 +3 3v output at 500ma 9 ground 10 button 7 i/o 11 ground 12 button 4 i/o 13 button 2 i/o 14 ground 15 button 0 i/o here is the da15 female as viewed from the front of a xdx32 player a button/led/ir board can be used to demonstrate the gpio and ir functions on a brightsign player this board is built by a third party manufacturer and can be purchased upon request ethernet brightsign xdx32 players have an rj45 connector for 10/100 base t ethernet, as well as power over ethernet (poe) capabilities the maximum ethernet cable length is 91 meters for poe applications and 100 meters for non poe applications to operate using poe, xdx32 players require type 2 poe supplying a minimum of 25w the equipment should be connected only to poe networks without routing to the outside plant the following table illustrates the pinout of the rj45 pin description pin description 1 tx+ 2 tx 3 rx+ 4 bi+ 5 bi 6 rx 7 bi+ 8 bi usb the xd1032 and xd1132 have two high speed (480 mbit) usb host ports, which also support usb 2 0 powered devices (up to 500ma for each port) the maximum length for the usb cable is 5 meters the following table illustrates the pinout of the usb host port pin description pin description 1 vbus 2 d 3 d+ 4 ground de15 vga connector the vga connector is able to output rgb video the following table illustrates the pinout of the de15 vga connector pin description pin description 1 red analog video output 2 green analog video output 3 blue analog video output 4 nc 5 digital ground 6 analog ground 7 analog ground 8 analog ground 9 +5v ddc supply 10 digital ground 11 nc 12 ddc sda 13 hsync output 14 vsync output 15 ddc scl rca component hd video connector component video is provided over the vga connector to display component video, you will need to use a vga to component converter see audio/video/image docid\ loevgvyhzty5gpexkt5bb for more details 3 5mm audio connector all xdx32 models have a single 3 5mm female audio connector, which transmits an analog stereo signal the full scale voltage output of the audio is 2v rms the minimum load impedance of the audio connector is 32ω the brightsign expansion module allows you to drive up to three sets of 5w headphones directly the audio connector has the following pinout tip left audio ring right audio sleeve ground for audio signal hdmi out connector the hdmi® out connector is used to send digital video and audio to hdmi enabled sink devices the following table illustrates the pinout of the hdmi connector pin description pin description 1 tx2p 2 ground 3 tx2n 4 tx1p 5 ground 6 tx1n 7 tx0p 8 ground 9 tx0n 10 txcp 11 ground 12 txcn 13 cec 14 nc 15 ddc scl 16 ddc sda 17 ground 18 +5v ddc 19 hpd (hot plug detect) hdmi in connector the hdmi in connector is used to receive digital video and audio from hdmi enabled source devices 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\@50ma ring ir input sleeve ir output 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
