On-site — plug the phone in
A field phone with an OTG serial cable plugs into the console port — ready in seconds, serial settings auto-matched.
Bridge to the cloud
The field phone registers its Console ID and keeps a secure relay link to the cloud.
One-tap invite
Generate a one-time invite link or QR code and hand it to the remote engineer.
Engineer joins in any browser
No client, no VPN — opening the link drops them straight into the live session.
Work the device live
Type, paste configs and capture boot logs with real-time echo — as if you were right there.
Collaborate with the team
Pull a few engineers into the same session — they join from anywhere, see everything and pitch in together.

From cable to first commandField creates a session code
Open the field page on a phone — it generates a 5-character Console ID (one letter + four digits, e.g. A1203). Share the invite link with the remote engineer.
OTG into the console port
USB-C / OTG → USB-RS232 adapter → console cable into the device port. In Chrome tap “Open serial”, default 9600-8-N-1.
Remote engineer starts typing
The invite link opens straight into a terminal. Anyone can watch; the most recent typer holds the keyboard. Paste configs and capture logs on the fly.

Questions, answered

How are the pieces connected? See the wiring diagram
i Only a phone plus an OTG serial cable is needed on site. Data travels over an encrypted path through the cloud relay, and the engineer simply joins from a browser — no public IP and no config changes on the device.
What hardware do I need on-site, and what does it cost?
An Android phone (Chrome or the native app), a USB-C/OTG to RS232 adapter (FTDI / CH340 / CP210x — driverless), and the device's own console cable. Total cost is tens of dollars — not a several-thousand-dollar dedicated console server.
Which devices are supported?
Anything with an RS232 console port: Cisco/Huawei switches and routers, firewalls, APs, server management serial ports. Baud rate is configurable, default 9600-8-N-1.
Does it work on iOS?
The field bridge needs Web Serial: Android Chrome or the native app works. iOS Safari doesn't support Web Serial yet — use a PC / Raspberry Pi running bridge-node instead. The engineer side is unlimited: any PC / Mac / phone browser can join the terminal.
Is it secure? Can others stumble into my session?
Everything runs over HTTPS / WSS, and session-level end-to-end encryption (AES-256-GCM) is one tap away — the key rides only in the invite link or is derived locally from a passphrase, so even the relay can't read the serial data. A field device must register its Console ID (with a device label) before it appears on the cloud, and the field side can require in-person approval before an engineer joins. A console ID only becomes valid after the field side registers it — you can't create a session from an unregistered ID.
What if several engineers join at once?
Multiple engineers can be online in one session: viewers watch read-only output, while keyboard control is held by exactly one person at a time and can be handed over. One keyboard, shared screen.
What happens if the field connection drops?
When the field side disconnects, the session is kept for a grace period; it reconnects automatically when the network recovers, and remote engineers see a clear notice instead of a dead terminal.
How much does it cost? Free, Sign up or Pro?
The field bridge is always free. On the engineer side there are three tiers: Free (guest, no account) — quick to try but ~30 minutes/day per console and solo only; Sign up — a free account removes the time limit, enables multi-engineer viewing/collaboration and 1 simultaneous console; Pro for concurrent consoles and priority relays — $5 for 30 days, one-time, auto-expires back to free. Buy Pro with a card: the card button above opens our payment partner's secure checkout, and your account is activated right after payment. Already have an activation code?
