Power Connector
The power connector for the XD series is rated for 12V @ 3A. The plug for the connector is a keyed and locking 4-pin connector. It is right-side positive.
DE-9 RS-232 Connector
The RS-232 connector is a male DE-9 (more commonly referred to as DB-9) connector. Like PCs, BrightSign XD players are DTE devices. The input to the chip accepts a range between +25V and -25V, so it is compatible with standard +12V and -12V signaling.
The baud rate is 115200, with no parity, 8 data bits, and 1 stop bit. There is no hardware or software flow control. The maximum cable length is 50 meters, and the total cable capacitance is 2500pF.
| Note |
|---|
NoteA 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 on the XD series of players:
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:
| Note |
|---|
NoteThe 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 XD series of players:

1 | IR blaster input | 2 | Ground |
3 | Button 6 I/O | 4 | Button 5 I/O |
5 | Button 3 I/O | 6 | Ground |

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 XD players have a standard RJ45 connector for 10/100 base-T Ethernet. The maximum length for the Ethernet cable is 100 meters. The following table illustrates the pinout of the RJ45:

5 | RC to ground | 6 | RX- |
7 | RC to ground | 8 | RC to ground |
USB
The XD1030 and XD1230 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.

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 this FAQ for more details.
3.5mm Audio Connector
The XD230, XD1030, and XD1230 each have one 3.5mm female audio connector, which transmits a stereo signal. The full-scale voltage output of the audio is 2V RMS. The output impedance of the audio connector is 32Ω.

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:

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 players even when they do not have power.
3.5mm IR Out
The IR blaster generates a space-encoded (NEC) signal. The two transported bit values of the NEC signal (0 and 1) are encoded using differing lengths of low-time IR pulses.
