2.2 - DIO
The Karbon 300 DIO terminals are optically isolated. This means that the terminal is separated from
other motherboard features for protection. In addition, the DIO requires external power from a
9-36VDC source through Pin 1 to function.

2.4 - Automotive Ignition Power Sensing (IGN)
The K300 3-pin power input terminal offers automotive ignition sensing. The ignition sensing timing
for power on and off delays can be modified through OnLogic’s microcontroller (MCU) using serial
commands. These commands allow setting the delay on startup after ignition is detected, the delay
until soft and hard shutdown when ignition is lost, and enabling/disabling ignition sensing. For more
information on ignition power sensing, and instructions on using these serial commands from
Windows or Linux, visit our Karbon series technical support site. 

2.6 - LAN
The dual LAN ports on Karbon 300 are PoE enabled for models K300-E3930-4P-P and
K300-E3950-8P-P. When PoE is disabled the LAN ports function as standard GbE ports. The single
LAN ports on all Karbon 300 models are standard GbE ports.

4 - Microcontroller
4.1 - Overview
The microcontroller on Karbon 300 controls several systems, including:
●Automotive ignition power sensing
●CAN bus
●DIO
●Status LEDs
●Power management and wake-up
●DisplayPort CEC and persistent EDID
A segment is exposed for user control via two serial ports. By reading and writing to these serial
ports, the user can send and receive CAN messages, read/set the DIO state, and select from a number
of configuration options. One port is dedicated to K300’s CAN bus, while another doubles as a serial
terminal and the DIO interface. Any configuration settings may be saved to non-volatile memory. This
means that upon a long power-off, the MCU settings will be retained.
To learn more about how to use the Karbon series MCU and Pykarbon interface tools, visit our Karbon
Series technical support site.
5 - Power Management
5.1 - Wake-Up Events
Karbon 300 supports multiple power states. The wake-up events can be configured in the MCU and
BIOS. This section describes the power management functions you can perform and gives
information on protection circuitry for power adapters.

5.2 - Protection Circuitry
Parameter
Value
Nominal operating voltage (Rated DC value of input)
9~36VDC
Undervoltage protection trip DC level (system turns off)
8.1V
Overvoltage protection trip DC level (system turns off)
42.5V
Maximum safe DC voltage (system not damaged)
50V
Minimum safe reverse voltage (system not damaged)
-40V
Ignition pin safe working voltage range (system not damaged)
-20~50V
These DC levels specified are the absolute max values for the pins for function and safety of the
system. The protection circuitry allows for brief transient voltages above these levels without the
system turning off (transients up to 50V for <30 ms).
A TVS protection on the input allows protection for:
●5000W peak pulse power capability at 10/1000µs waveform, repetition rate (duty cycles):
.01%
●IEC-61000-4-2 ESD 30kV(Air), 30kV (Contact)
●EFT protection in accordance with IEC 61000-4-4
