XTx43 Hardware Interfaces

this section describes the characteristics and operation of all connectors on the xt243 and xt1143 power connector the power connector for the xt243 and xt1143 is rated for 12v\@3a the plug is a right side positive, locking 2 pin (1x2) connector 3 5mm serial the uart (asynchronous serial) interface is a 3 5mm (1/8") 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 xtx43 units that are rev h or later support full rs 232 signaling the serial transmit pin on earlier versions of the xtx43 does not comply with voltage levels for rs 232 signaling (which requires a voltage below 3v for logical 1) in practice, the serial port can interoperate successfully with the majority of rs 232 receivers, but some devices (including some projectors and crestron equipment) require strict conformance to rs 232 levels and will not accept 0v as logical 1 in these instances, you can connect the brightsign player to the serial device using a usb to serial cable 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 gpio the xt243 and xt1143 have a 12 pin gpio switch and led connector, which allows the player to control external leds or other devices requiring 24ma of current or less 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 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 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 true false

91 meters for poe applications and 100 meters for non poe applications; the allowed length can be higher or lower depending on the quality of the cable the equipment should be connected only to poe networks without routing to the outside plant usb the xt1143 has two usb 2 0 ports one type a and one type c the type a connector can act as a dedicated charging port (dcp) when the two data pins are shorted together, and the type c connector can operate as either a host or a device (i e a dual role port) the type a connector can supply up to 1 5a of power for peripherals, while the type c connector can supply up to 1a note that these values are subject to a xtx43 environmental & power docid\ t8fl8caru0cbdgquengej for peripherals both ports are capable of transfer speeds up to 480
