2.3.3 Onboard Serial Console Port
The serial console port is used for locally accessing SEC2 by RS232 port. The console port uses the
RJ45 connector and is next to Ethernet port.
Therefore, please be careful to plug in the right
connector!
In addition to the serial console signal, the console RJ45 port also provides GPIO (programmable I/O
signal) function. The GPIO port is CMOS I/O and programmable as digital input or output. Power up
setting is digital input mode with 75K ohm pull up resistor.
