Machine data transmission

Machine data upload board for self-service equipment.

Use QuLink when a machine does not only need control, but also needs to send status, telemetry, sensor values, usage logs, fault alerts, or operation results to your cloud.

Project fit

Data problems this solves

Buyer signals

Operators need to know whether machines are online, faulted, idle, or running.
Smart cabinets, vending, charging, water, and service devices need usage or result upload.
Legacy machines need 4G connectivity or a server callback without a full controller rebuild.
OEM projects need telemetry, logs, and remote status as part of the board design.

What to send first

Machine photo or existing board photo
Interface or wiring note if available
Target action after API command or payment
Whether telemetry or data upload is required

Integration model

Data bridge between machine and server

QuLink reads machine-side signals or protocol data, normalizes them as events, and sends them to your backend for operations, billing, support, or analytics.

Data sources: sensor input, UART, RS485, serial frame, controller status, vend/session result
Connectivity: 4G/cellular module, server callback, webhook, project-specific integration
Events: device.online, telemetry.updated, machine.fault, session.completed, vend.result
Project mode: retrofit data bridge, connected machine rollout, OEM telemetry board

Workflow

From machine interface to API-controlled result.

Choose data points

Define what the machine should send: status, fault, metering, result, sensor, or usage data.

Confirm source interface

Check whether data comes from GPIO, serial, RS485, MDB, sensors, or a custom controller.

Map events

QuLink converts machine signals into webhook events your server can process.

Verify in field

Test online/offline behavior, retries, data format, and fault conditions with real machines.

API example

A clear server command or webhook for the machine-side action.

The exact command fields depend on machine interface, firmware profile, and whether payment or your own app triggers the action.

POST /webhooks/qulink
{
  "event": "telemetry.updated",
  "device_id": "CABINET-31",
  "telemetry": {
    "online": true,
    "temperature_c": 4.8,
    "door_open": false
  }
}

Start the project

Send the first machine details before writing a full spec.

Send the machine type, data points needed, signal/protocol source, connectivity requirement, and target server workflow.

Useful first message

Machine type and target country
Machine photo, board photo, or wiring photo
Action after API command or payment
Data upload and estimated quantity

FAQ

Questions buyers usually ask before a sample test.

Can QuLink upload data without controlling the machine?

Yes. Some projects use QuLink mainly as a data bridge, while others combine data upload with control commands.

Can it work with RS485 or UART?

Yes, serial, UART, and RS485 projects can be evaluated based on frame format and device behavior.

Can data be sent to our own server?

Yes. Your backend remains the owner of the data workflow; QuLink provides the machine-side bridge and callbacks.
