HOW TO CONNECT?
Operating System: Windows
USB Connection: Requires a USB-C or Micro-USB cable for a direct connection to the gimbal/Payloads
USB-C Configuration for Gremsy Payloads (PC Connection)
Gremsy payloads support USB Ethernet connection for direct access and configuration. To establish communication between the payload and your PC, you must manually configure the IPv4 settings on your PC to match the payload’s subnet.
This guide outlines the USB-C connection and IP configuration steps for the following payloads:
VIO
ZIO
G-Hadron (Mainboard)
Note: Ensure the chosen IP address on your PC does not conflict with the payload's IP or any other devices on the network.
1. VIO Payload Configuration
Payload IP Address:
192.168.55.1
Connection Port: USB-C located on the bottom of the camera
Steps:
Connect the USB-C cable from the bottom of the VIO camera to your PC.
On your PC, go to: Control Panel > Network and Sharing Center > Change adapter settings
Right-click the new Ethernet device (USB Ethernet), choose Properties.
Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
Set the static IP address of your PC to something in the same subnet, e.g.:
IP address:
192.168.55.10
Subnet mask:
255.255.255.0
Leave Default gateway blank
Click OK to apply changes.
2. ZIO Payload Configuration
Payload IP Address:
192.168.12.240
Connection Port: USB-C located on the side of the camera
Steps:
Connect the USB-C cable from the side of the ZIO camera to your PC.
Configure the PC’s IP to an address in the
192.168.12.x
range, e.g.:IP address:
192.168.12.10
Subnet mask:
255.255.255.0
Leave Default gateway blank
3. G-Hadron Mainboard Configuration
Payload IP Address:
192.168.144.25
Connection Port: USB-C (marked as HOST) on the mainboard
Steps:
Connect the USB-C cable from the HOST port of the G-Hadron mainboard to your PC.
Configure the PC’s IP to an address in the
192.168.144.x
range, e.g.:IP address:
192.168.144.10
Subnet mask:
255.255.255.0
Leave Default gateway blank
4. Connect to Gremsy Payload Assistance Desktop
Step 1: Launch the Application
Open the Payload Assistance Desktop application on your PC.
Step 2: Verify Application Status
Upon launch, the interface will display a "Disconnect" status if the connection has not been initialized.
Step 3: Configure RTSP and Control Settings
Click on the
SETTING
button in the main interface.In the settings panel, locate the RTSP URL section.
Example RTSP URL Format:
rtsp://<IP>:8554/<mountpoint>
Example:
rtsp://192.168.55.1:8554/payload
8554 is the default video stream port.
/payload
is the mount point and can be verified in the Web Setting interface of the payload.The IP address depends on the payload being used.
Note: The RTSP URL format is universal; only the IP address and mount point need to be adjusted to match the connected payload.
