BrightSign 4K242, 4K1042, 4K1142
SDHC/SDXC and MicroSD Slots
The 4K series has one SDHC/SDXC and one internal MicroSD card slot, both capable of transferring a 25 Mbit/sec video
stream, one 5.1 AC3 stream (pass-through), and three stereo PCM tracks simultaneously. There is no inherent limit on
the storage capacity of SD cards used for 4K series players.
NAND Flash
BrightSign players have a built-in NAND flash. All the code for the player is stored on the NAND flash, and it may also be
possible to store some content on the NAND flash, which is connected directly to the CPU.
Ethernet
The 10/100/1000 Base-T Ethernet is implemented on 4K players by directly interfacing with the BCM7252/BCM7444. The
player has on-board Ethernet magnetics and termination for the RJ-45 cable.
USB 2.0/3.0
The USB 2.0/3.0 high-speed host controller is implemented internally on the BCM7252/BCM7444 SOC. The board utilizes
over-current protected switches that can be used to turn the power to USB devices on or off or to detect over-current
situations.
