SERIAL COMMUNICATION PROTOCOL

Here is the complete list of commands provided through the serial connection. The pinout is indicated on the enclosure.
Typically, commands will return ACK in case of success and NACK in case of failure.
Note that if the serial interface was disabled using REST API, commands will not be parsed, and no response will be provided.
Baud rate: 9600 // Data bits: 8 // Stop bits: 1 // Parity: None // Flow control: None

The sign specifies the direction.
We multiply the argument by the camera
smallest step, and if the speed is too fast, we go
as fast as the camera allows. We recommend
using values between -10 and 10.| Relative pan
TILT| 1 argument (integer)
The sign specifies the direction.
We multiply the argument by the camera
smallest step, and if the speed is too fast, we go
as fast as the camera allows. We recommend
using values between -10 and 10.| Relative tilt
ZOOM| 1 argument (integer)
The sign specifies the direction.
We multiply the argument by the camera
smallest step, and if the speed is too fast, we go
as fast as the camera allows. We recommend
using values between -10 and 10.| Relative zoom
SETHDMI| 1 argument (integer)
0 => 1080P60
1 => 1080P50
2 => 720P60
3 => 720P50
4 => 4K24
5 => 4K25
6 => 4K30| Set HDMI output mode
SETVIDEOFORMAT| 1 argument (integer)
0 => 1st preferred format
1 => 2nd preferred format
2 => 3rd preferred format
3 => 4th preferred format| Set USB video input format

LAN COMMUNICATION PROTOCOL

You can access the device settings through its LAN interface. The LAN interface uses DHCP. You can obtain the IP from the Inogeni Control App or from the serial port IP command.

CDC-NCM COMMUNICATION PROTOCOL

The device can also be controlled through the CDC-NCM interface exposed on the USB2.0 device port.
This interface has the same functions as the LAN interface, except the requests are done through USB in order to ease configuration.
CDC-NCM IP address: 169.254.10.10

WEBPAGE

Here is the webpage that can be used to configure and upgrade the device.
The username is “admin” and the default password is “admin”.

The first time you access the webpage, your web browser is likely to complain that the connection is insecure. The reason for this is that we are using a self-signed HTTPS certificate because certificate providers will not provide certificates for addresses that are not globally accessible.
The webpage can set HDMI resolution, USB video input format, webpage password, or the REST API access token. Please note that in the case of the REST API token, we can only ask for the device to generate a new randomly generated token. It can also be used to upgrade the device firmware.

REST API

The REST API needs to have Authorization: Bearer in the HTTP header. The response will be JSON formatted with a “message” field containing a JSON string explaining the cause of the error if any. Note that we are using a self-signed certificate.
Here is the complete list of commands supported through the REST API

GET
https:///api/v1/status.| | 200 => success
401 => authorization error| A JSON object with multiple
fields
