7.3.3
Micro SD Card
This is a socket for a standard micro SD card.
The SD Card can be used to record encoded video, upgrade the encoder firmware or other custom
functions.
7.3.4
Ethernet PHY, RS232
This header provides access to the Gb Ethernet side of the PHY on board the Main Encoder PCB. It
mates with J22 on the I/O Jack PCB. This connector also provides access to the Linux console, using
serial port 0, with RS232 levels.
The pin assignments are below.
The UART4_TXD and UART4_RXD signals are only present on the encoder version 2. The v1 encoder
has no connections to these pins.
The board set uses a 2x8 connector with 1.27mm pitch.
