Introduction
The Manifold 2 is DJI’s second-generation microcomputer for DJI SDK developers. There are two
versions: Manifold 2-G (128GB), Manifold 2-C (256GB). The Manifold 2-G is equipped with the Wi-Fi-
ready NVIDIA®JetsonTM TX2 module, capable of rapid complex graphics processing. The Manifold 2-C
has an Intel®CoreTM i7-8550U processor, boasting excellent processing power and responsiveness.
With a variety of ports to connect different external devices, the Manifold 2 is compatible with many
DJI drone platforms, ight control systems and additional devices*. The Manifold 2 is exible and
expandable, making it the go-to tool for developers.
* Support for additional DJI products will be added as testing and development continues. Visit the Manifold 2 product page
on dji.com for the most current list. http://www.dji.com/manifold-2

Overview
Manifold 2
The illustrations below use the Manifold 2-G as an example. Unless otherwise specified, the
descriptions apply to the both models in the Manifold 2 series.
1. Ethernet Port (RJ-45)
Connect a network cable to the port to access the Internet.
2. USB 3.0 Ports (Type A)
Connect external USB 3.0 devices.
3. HDMI Output Port
Connect a display device.
4. Antenna Ports (for the Manifold 2-G only)
Mount the Wi-Fi antennas to the ports to access the Internet via Wi-Fi. Make sure that the two
antennas are vertical to each other or towards to the signal source. DO NOT block the antennas
with metal objects.
5. Power Ports
Connect an external power source to supply power for the Manifold 2. The ports are standard XT30
ports with an input voltage of 13.2 - 27 V for the Manifold 2-G and 15.2 - 27 V for the Manifold 2-C
and are independent from each other. When connecting power sources to both ports, the Manifold
2 will automatically choose the power source with a higher voltage.
6. Power Indicator
The indicator is on when the Manifold 2 is connected to a power source, and off when
disconnected.
7. USB 3.0 Port (Micro-B)
This port on the Manifold 2-G allows it to be used as both a host and a device. Use it as a host by
connecting a USB device using the OTG cable. Use it as a device for image backup and system
recovery or as a regular USB 3.0 device by connecting it to a host using a Micro USB cable.
This port on the Manifold 2-C allows the Manifold 2-C to be used as a host only. Connect the OTG
cable to the Manifold 2-C and then connect a USB device to the other end of the OTG cable.

The UART0 port is for the debug terminal with a baud rate of 115200. DO NOT connect
it to the DJI SDK API Port or any other non-string stream input port.
Access UART0 from ttyS0 in the kernel of the operating system, while access UART1 (for
the Manifold 2-G only) from ttTHS2 in the kernel of the operating system.
The UART ports of the Manifold 2-G support a baud rate up to 3M. The nominal baud
rate 921600 has an actual baud rate of 910000. As a result, when connecting other
devices that have a baud rate error against the nominal value, such as some OSDK
devices, the UART ports may not be able to communicate properly with these devices.
In these cases, it is recommended to use other baud rates.
The UART port of the Manifold 2-C supports a baud rate up to 115200.
9. CAN Ports (for the Manifold 2-G only)
Only the Manifold 2-G has CAN ports. The ports on the Manifold 2-C are marked with N/A. The
operating level of the CAN ports is 3.3 V TTL. The maximum transmission speed is 2 Mbps. These
ports cannot supply power to the external devices.

Manifold 2. DO NOT hot swap the devices connected to the I/O port to avoid damage to the
devices.

respectively.
8. UART Ports

Power Distribution Unit
Connect the Power Distribution Unit to a power source to power the Manifold 2 and other external
devices for debugging. Make sure to connect corresponding devices according to the specications
of the ports.
1. Low Power Output Port (XT30)
The maximum continuous current is 15 A and the maximum peak current is 30A. The power input
of this port is from Port 7 (Power Adapter Input Port).
2-6. High Power Output Port (XT30)
The maximum continuous current is 15 A and the maximum peak current is 30A. The ve ports are
parallel with power input from Port 8 (High Power Input Port).
7. Power Adapter Input Port
Connect the power adapter to the AC power source (100 - 240 V, 50/60 Hz), and then Port 1 can
supply power to the Manifold 2 continuously. Many of DJI’s power adapters are compatible with
this port. Refer to the Specications for details.
The following situation is an example to use this port. Connect this port to a power source, and
connect Port 1 to the power port of the Manifold 2. The Manifold 2 will stay powered on even when
replacing the input battery connected to Port 8 on the Power Distribution Unit.
8. High Power Input Port (XT60)
Connect a 4S - 6S LiPo battery to supply power to the Manifold 2 and other devices through Ports
2 - 6 on this unit. The maximum continuous current is 30 A and the maximum peak current is 60 A.
Port 1 and one of Ports 2 - 6 can be connected to the two power ports on the Manifold 2
simultaneously by independent power sources to the Manifold 2.
It is recommended to use the Power Distribution Unit for power management since its
electromagnetic compatibility can reduce interference to the GNSS or Wi-Fi signal from the
power supply.
Connect high-power devices to Ports 2 - 6 in increasing order of power consumption to help
reduce heat generation.

System Conguration
Users can perform basic setup in the terminal interface.
Basic Configuration
The Manifold 2 comes with the Ubuntu 16.04 operating system pre-installed. After powering on
the Manifold 2, then connect a monitor with a HDMI port, mouse and keyboard to log in with the
information below.
User name: dji Password: dji
Network Configuration
Access the Internet using a network cable or Wi-Fi (for the Manifold 2-G only). If DHCP service is
available on the connected network, an IP address will be assigned to the Manifold 2 automatically.
Otherwise, run the following commands to obtain an IP address:
Wired Network
$ sudo ifcong eth0 xxx.xxx.xxx.xxx
$ ifcong
Wireless Network
$ sudo ifcong wlan0 xxx.xxx.xxx.xxx
$ ifcong
“xxx.xxx.xxx.xxx” is the IP address that you wish to use. The commands above can also be used to
check if the conguration is correct.

BIOS Settings
The Manifold 2-C’s built-in CMOS battery could run out if unused for a long time, which could result in
a loss of BIOS settings. Follow the instructions below to re-load the BIOS settings.
1. Power on the Manifold 2-C. If the CMOS battery has run out, the information on the terminal screen
will prompt for user conguration.
2. Press the Esc or Del key on the keyboard to enter BIOS.
3. Press F3 to load the default BIOS settings, and then press F4 to save and exit.
Make sure to operate the above BIOS settings after the CMOS battery runs out. Otherwise, a
hardware error may occur on the Manifold 2-C.
To avoid damage from a dead CMOS battery, it is recommended to keep the Manifold 2-C
powered on for at least 30 minutes to charge the CMOS battery when using for the rst time
or after long-term storage without power supply.
System Image
Only the Manifold 2-G supports Recovery mode, System Recovery, and Image Backup. Connect the
Manifold 2-G to a host and enter Recovery mode to recover the system and create an image backup.
The method of system recovery for the Manifold 2-C is similar to a regular X86 computer.
Preparation
1. Prepare a computer with the Ubuntu operating system as a host, for example a Manifold 2-C. Make
sure there is at least 32 GB on the hard disk.
2. Download the latest image from the following link. The image le includes the ofcial DJI image
and tools for image backup and system recovery.
https://www.dji.com/manifold-2/info#downloads
Entering Recovery Mode
1. Connect the Button I/O Extension Unit to the Manifold 2-G.
2. Connect the USB 3.0 port (Micro-B) on the Manifold 2-G to the host.
3. Connect the Manifold 2-G to a power source.
4. Press and hold the RCV button on the Button I/O Extension Unit, then press and hold the RST
button. Release both buttons after two seconds.
5. Type in $ lsusb in the terminal of the host. An NVIDIA device will be listed to indicate that the
Manifold 2-G has entered Recovery mode. If not, check if the connection and operation for
entering Recovery mode are correct, and try again.
Image Backup
Users can create an image backup to recover the system. There is no need to create an image
backup if users recover the system using the ofcial DJI image.
