On-Board Switch
The on-board switch is connected to the GPIO02. The GPIO02 is pulled low when the service (SVC) button is pressed.
Conversely, a pull-up on the button normally sets the GPIO02 to be pulled high.
Reset Switch/GPIO Button
The on-board switch is connected to the reset circuit. Pressing down the reset button will send an initial signal to the
system software, and holding the reset button low for approximately 4 seconds will cause a hard reset.
SDHC/SDXC Slot
The HD222 and HD1022 series has one SDHC/SDXC slot 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 with the player.
NAND Flash
BrightSign players have a built-in NAND flash. All the code for the player is stored on the NAND flash. It may also be
possible to store some content on the NAND flash, which is connected directly to the CPU.
Ethernet
The 10/100 Base-T Ethernet is implemented on the players by directly interfacing with the BCM7241. The player has on-
board Ethernet magnetics and termination for the RJ-45 cable.
