# Self-Streaming with Loop Back
## Overview
onocoy has introduced a Loop Back feature that allows miners to stream the data from their own stations back to themselves — without consuming Data Credits.
This is made possible through the use of NTRIP server credentials, which give miners direct, cost-free access to their own mountpoints.
***
## What Is Loop Back?
Loop Back enables a miner to act simultaneously as both a data provider and a data consumer for their own streams. Instead of paying Data Credits to access correction data from their own station, the miner can use a dedicated server credential to receive that data for free.
Key capabilities:
* Stream up to 3 simultaneous self-streams at no Data Credit cost
* Use any standard NTRIP client with the server credential username and password
* Ideal for local rovers, quality control setups, or redundant positioning workflows
## Getting Your Server Credential
Server credentials are managed directly from the onocoy dashboard. To create or edit one:
1. Navigate to your station's credential management section (go to onocoy console at then click "Reference Stations" then click "NTRIP Credentials").
2. Select Edit credential (click the pencil drawing of the credential you are interested in)
3. Now you can copy the credential and password and paste it into your rover settings as username/password combination.
4. If necessary, you can configure the coordinate frame in the following field:
Advanced Settings: Reference Frame (Self-Streaming)
* Default value: ITRF2020 (current epoch)
* Other reference frames may be available for your geographic area of interest.
This option is only relevant when using the credential to stream your own mountpoint back to yourself. It has no effect on how your data is broadcast to other network users.
***
## Connect Your Rover
Configure your rover with these settings:
* Set the NTRIP caster to and port `2101`
* Use port `2121` for TLS connections
* Choose your mountpoint name from the list in the console (In use by)
* Fill in your server credential as username/password
You should be good to go!
***
## Important Limitations
The loopback feature is scoped strictly to the miner's own mountpoint. This means:
* ✅ You can only stream your mountpoint associated with that specific credential
* ❌ You **cannot** stream any other mountpoints, including:
* EPHEMERIS streams
* NRBY (nearby stations) streams
* Any other network mountpoints
If you need access to other mountpoints (e.g., nearby reference stations or ephemeris data), you must use standard Data Credits rather than a server credential.
Prohibition of Resale: The data retrieved via loopback is for internal use only; redistribution or resale to third parties is prohibited
