Kesesuaian proyek
Untuk mesin dan proyek yang sesuai
Sinyal kebutuhan
- Sites without reliable local network or a local PC.
- Machines that expose serial, RS485, pulse, or relay signals.
- Projects that need heartbeat, session, fault, or meter data.
- Teams that want data in their own backend, not a closed portal.
Yang perlu dikirim
- Foto mesin atau papan saat ini
- Catatan interface atau wiring
- Aksi target setelah API atau pembayaran
- Apakah perlu upload data
Kurang cocok jika
- The machine has no usable data or control interface.
- You need guaranteed cellular coverage before a site survey.
- You only need a local dashboard with no backend integration.
Model integrasi
Dari perintah API ke aksi mesin
Sistem pembayaran atau backend Anda mengirim perintah, QuLink menjalankan aksi mesin dan mengirim hasilnya. Interface dikonfirmasi pada sampel.

Alur kerja
Dari interface mesin ke hasil yang dikontrol API.
Map the command
Define the API command, machine action, result fields, timeout, and fault behavior.
Test one machine
Validate the command, machine action, result, and reconnect behavior on a sample.
Configure the rollout
Confirm connector, firmware, quantity, and support before production.
Contoh API
Contoh perintah server atau webhook untuk aksi machine-side.
Field perintah bergantung pada interface mesin, profil firmware, dan apakah pembayaran atau aplikasi Anda yang memicu aksi.
POST /v1/devices/SITE-12/events
{
"event": "telemetry",
"device_id": "SITE-12",
"fields": ["heartbeat", "session_state", "fault"]
}

Ceritakan apa yang harus mesin lakukan, kirim, atau laporkan.
Kirim model mesin, foto controller, dan aksi yang dibutuhkan. Kami konfirmasi jalur interface Pengendali IoT 4G dan langkah uji sampel.
A good first message
If you are unsure about the exact interface, send what you have. Photos often answer more than a long spec.
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after payment or API command
- Need data upload? expected quantity?
Fastest first step
- Send a machine photo
- Describe the action after API or payment
- Tell us if data upload is needed
FAQ
Pertanyaan yang biasanya muncul sebelum uji sampel.
Does it work with our own backend?
Yes. Event delivery can be configured for your HTTP API, webhook, or MQTT broker, depending on the project.
What data can it report?
It depends on the machine interface. Heartbeat, session state, relay or pulse events, and fault signals are common starting points.
Does it need a SIM card?
Yes for cellular operation. SIM, antenna, and site coverage are confirmed during the sample test.
What should I send first?
Controller model, serial or pulse interface, data fields needed, and where the data should go.
