DE9 RS-232 Serial The RS-232 interface is a male DE9 connector. The BrightSign 4K player is a DTE device, 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 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: All information provided in this reference manual applies to products under development. - Page 14 All information provided in this reference manual applies to products under development.

The SPDIF_OPT signal is generated within the BCM7444 CPU, which is connected directly to the SPDIF output. Wireless BrightSign 4K 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. -

Power Supply There are several voltage levels present in BrightSign 4K players. Reset BrightSign 4K 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. BCM7444/7252 CPU The 4K242 and 4K1042 utilize a BCM7252 CPU, while the 4K1142 utilizes a BCM7444 CPU. -

Audio Outputs BrightSign 4K 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). -
