# Site device installation — know it BEFORE you are standing in the booth
A field runbook: for every device we deploy, its **factory address and credentials**, the **tool**
you need, **what the app configures by itself** at assign time versus **what must be done by hand on
the device**, and the **traps already paid for** on park-buzi and the lab. The [[appliance-provisioning]]
runbook covers the booth PC (OS, disk, Docker, Periphery); this page covers everything plugged into
it. Written 2026-09-09 after an evening lost to a printer whose factory address nobody had written
down ([[k200l-printer]]).
Rule of thumb that explains most of this page: **every field device ships on its own private
subnet with DHCP off, and none of them announce themselves.** You bring a laptop that can take a
second static address, you put it on the device's factory subnet, you move the device to the site
plan, and only then does anything else see it.
## Before leaving the office
**Bring**
- A laptop with an Ethernet port and the right to add a **second static IPv4 address** to it
(Windows: adapter → IPv4 → Advanced → add). Under WSL, remember the source-address bug
([[wsl-dev-networking]]): after adding a temporary address, `ping` may work while HTTP times out.
- The Dingtian reader tool **`QRCode_v1_6_5.exe`** (Windows) — the only way to set a DT-008's IP,
server target, prefixes and symbologies. A browser is enough for everything else.
- Patch cables, a USB A–B cable (printers), the site's **address plan** (below) filled in, the
app **admin** password, and a fresh Komodo **onboarding key** if the booth PC is new
([[appliance-provisioning]] §7a).
- The **serials** if already known: DT-008 `cjihao` (on the reader's label / in the tool), camera
MAC/serial, printer model (label on the bottom — the K200L's own web UI calls it "POS-80").
**Address plan** — the device VLAN ([[network-isolation]]) is `10.0.10.0/24` on both sites so far,
**every device static, DHCP off everywhere**. The convention from park-buzi / park-lab:
| Address | Device | Factory address it came from |
| --- | --- | --- |
| 10.0.10.1 | VLAN gateway (switch/router) | — |
| 10.0.10.5 | [[dingtian-relay]] board (barriers + inputs) | `192.168.1.100` |
| 10.0.10.7 / .8 | [[dingtian-dt008-reader]] entry / exit (**unique IP each**) | `192.168.1.99` |
| 10.0.10.9 | entry-dispenser printer (park-buzi: Cashino KP-300H) | *not recorded — fill in* |
| 10.0.10.10 | booth-receipt printer (park-buzi: [[rongta-printer]]) | *not recorded — fill in* |
| 10.0.10.11 / .7 (lab) | [[k200l-printer]] | `192.168.123.100` |
| 10.0.10.12 / .13 | [[lpr-camera]] entry / exit (Hikvision DS-2CD1047G3H-LIU) | `192.168.1.64` (Hikvision default; needs activation) |
| 10.0.10.203 | the booth PC on the device VLAN (**the `backendIp` every device pushes to**) | — |
Fill the real numbers into the site record before you drive; the wizard asks for the booth's push
address once and writes it into the Dingtian and the cameras.
## 1. Dingtian relay board (DT-R004 family) — barriers, button, radar
**Factory:** IP `192.168.1.100`, web UI on port 80, login `admin` / `admin`, UDP `60000` (binary) /
`60001` (string), multicast discovery `224.0.2.11:60000`. See [[dingtian-relay]].
**By hand, on the device (browser at its factory address):** set the site IP / mask / gateway in
the Network page and reboot. That is the only thing you *must* do by hand. Optional but recommended:
in the web UI **disable the UDP2 "string" protocol** (a password-less relay-fire path); the app's
harden step tries to disable it and **warns if the device refused** — then do it here.
**Wiring:** button on **I1** (NO contact to GND, idles HIGH, pulls LOW on press); radar dry contact
on **I2**; barrier operator's open input on **relay 1** (entry) and **relay 2** (exit); a spare relay
for the entry button lamp ([[button-light-indicator]]). One board can carry both barriers; two
distant barriers = two boards ([[entry-exit-points]]).
**What the wizard does on assign** ([[first-run-setup]], [[device-input-flow]]): finds the board by
multicast ("Scan for controllers" — laptop/booth must share the L2 segment), checks and clears
`input_link_relay` (factory default auto-fires a relay from its input — the app must decide, not the
board), sets a random **relay password** (UDP binary), disables every other control channel, rotates
the web login, and writes the **input push** URL + per-device Digest credentials so button/radar
edges reach the booth PC. You enter the relay map (which relay is entry/exit/both) and the inputs
(button → its relay; radar → `presence`, `activeLow` if it idles opposite the button —
[[hikvision-radar]]).
**Traps**
- The HTTP CGI API is **unauthenticated** on this firmware; `admin/admin` gates only the web page.
Never enable `session_en` — it bricks the config API and only a **factory reset** recovers. The
VLAN is the boundary, not the login ([[dingtian-relay]] §Hardening).
- A relay password mismatch shows as **"offline despite ping"**: the status query is answered only
with the right password. Re-assign / re-enter the relay password in the device form.
- "Relay test" in Setup pulses real hardware and signs a ledger event — use it to prove wiring,
once per relay.
## 2. Dingtian DT-008 QR + RFID readers
**Factory:** IP `192.168.1.99`; no web UI — everything is set with **`QRCode_v1_6_5.exe`** over the
network. See [[dingtian-dt008-reader]].
**By hand, in the tool, per reader:**
1. **Unique device IP** (`.7` entry, `.8` exit). Two readers on one IP was the 2026-06-18
"wrong barrier" incident — scans land on the wrong device row.
2. **Server IP** = the booth PC (`10.0.10.203`), **server port** = the booth's HTTP port (80 behind
the prod proxy); "server language" can stay whatever it is (php/jsp/asp/aspx/cgi are all
served — the reader GETs `/qa/mcardsea.<ext>`).
3. **Output prefixes:** `QRCode Output Prefix` = `Q:`, `Card Output Prefix` = `K:` (channel
tagging — a printed clone of a card cannot pass as the card).
4. **Card Input format = `6H`** (defines the UID shape enrolled; changing it later orphans every
card).
5. **Symbologies: QR + Code128 only**, minimum decode length ≥ 10, checksums on — otherwise low
sun through the striped arm produces phantom 6-digit reads (park-buzi, July).
6. Note the **serial (`cjihao`)** — the wizard binds the reader by serial, not by IP.
**In the wizard:** add the reader with its serial, bind it to the controller relay it sits at
(direction is inherited from the relay). **Verify:** scan a card — the server log shows
`READ serial=… → device=… verdict=… dir=…`; the reader beeps **twice** on accept, once on refuse,
and only after the server's reply (no reply = no beep, the scan still happened).
**Trap:** a factory reset or a swapped unit silently loses items 3–5. Re-apply all of them.
## 3. Hikvision camera (DS-2CD1047G3H-LIU, AcuSense) — ANPR + snapshots
**Factory:** `192.168.1.64`, **inactive** until a password is set on first boot (browser at that
address or the SADP tool); after activation the login is `admin` / the password you chose. Site
convention so far: `admin` / `admin123` on the first units (change per site and record it). See
[[lpr-camera]].
**By hand, on the camera:**
1. Activate, set the site IP, disable DHCP. Time: NTP off-site is unavailable — the app re-syncs
the camera clock from the booth at every offline→ready edge ([[clock-integrity]]).
2. **Streams:** the snapshot the app pulls MUST come from the **sub stream** (`102`) — the main
stream's ISAPI snapshot returns **503 instantly, always, on this model**. Set the sub stream to
the highest resolution the camera allows.
3. **Event push:** Event → Motion Detection with the AcuSense **Detection Target = Vehicle** filter
ON, "Notify Surveillance Center" on, then Alarm Settings → **Alarm Server** →
`http://10.0.10.203/api/devices/hikvision/<deviceId>/event`. The `deviceId` exists only after
the wizard assign, so: **assign first, then come back to the camera**. Digest user/password if
the firmware allows it (the wizard shows them).
4. "Enable Hikvision-CGI" is a different legacy surface — **not** needed for ISAPI.
5. **Close the web UI / live view when done.** The camera has few connection slots; a browser left
open makes every snapshot pull 503 "Device Busy" ([[lpr-camera]] §503).
**In the wizard:** driver `hikvision`, host, `admin` password, channel 1, **stream = Sub**, ANPR on,
bind to the relay at that barrier, `alarmPushEnabled` on.
**Verify, do not assume:** drive a car through and look at `GET /api/events` (or the log) for an
alarm with `targetType=vehicle`. A camera configured for push that has sent **zero** alarms is
broken on its side: pull its *Diagnose Information*; `Main Db is broken` means a corrupt config
database → **factory reset**, then redo 1–3 (the Vehicle target filter defaults OFF after a reset).
Point the Alarm Server at a dumb HTTP sink on the laptop if you need to see the verbatim body
([[lpr-camera]] §"auto-enter but not auto-exit").
## 4. Radar (vehicle presence at the entry barrier)
A dry-contact sensor into a Dingtian input, nothing on the network. Check with the board's input
status (`00` query → `relays:inputs`) whether it **idles HIGH or LOW**; if it idles opposite the
button, set `activeLow` on that input in the wizard, or the gate inverts (tickets only when the
lane is empty). It is advisory: it gates the button, it never opens anything ([[hikvision-radar]],
[[entry-double-press]]).
## 5. Printers — three models, one byte stream, different status
All print the same ESC/POS bytes over **raw TCP 9100** or **USB (`/dev/usb/lpN`)**; what differs
is whether the app can see paper/cover state ([[printer-status-monitoring]],
[[printer-usb-transport]]). Roles: **entry-dispenser** outside at the lane, **booth-receipt**
inside (receipts, subscription cards, Z-reports, and the backup for entry tickets), **wash-desk**
if the site has a Car Wash ([[printer-roles-failover]]). Higher `failoverRank` = tried first.
| Model | Factory network | Config UI | App driver | Live status |
| --- | --- | --- | --- | --- |
| [[k200l-printer]] (Xprinter/ICS K200L, "POS-80" board; **the park-buzi unit**) | `192.168.123.100/24`, DHCP off | browser, port 80, no login: Configuration → fixed IP → Save → Restart | **`k200l`** | over LAN: cover / paper / cutter / off-line from `/prt_status.htm`; over USB: reachability only |
| [[rongta-printer]] (RP-series) | *not recorded — fill in* | status page `/prn_stat.htm` on port 80 | `rongta` | over LAN: full; USB: reachability |
| Cashino KP-300H | *not recorded — fill in* | *not recorded* | `escpos` (generic) | reachability only, by design — no trustworthy status source |
**Prefer LAN over USB** wherever a cable can reach: the booth sees a real amber "cover open, paper
out" while a roll is changed, and the `usblp` path (udev rule, node renumbering, the park-buzi
"offline after reload" mystery) drops out of the picture. USB needs the appliance's `usblp` +
udev rule ([[printer-usb-transport]] §Provisioning) and the printer shows up as `/dev/usb/lpN`,
numbered by plug order.
**Verify:** the wizard's "Test" only *probes* (opens the port / the device node) — it prints
nothing. Print something real: a subscription with a QR credential auto-prints its card and has a
**Reprint card** button; a payment prints a receipt; a wash till prints slips. Check the Cashino's
barcode with a real ticket (the KP-300H garbled overflowing barcodes until the geometry fix).
## 6. Order of work on site
1. Address plan on paper; VLAN ports patched; booth PC up with its device-VLAN address.
2. Dingtian: factory address → site address (browser) → wire button, radar, barriers.
3. Wizard: **controllers first** (the relay map + inputs); "Relay test" each barrier.
4. Readers: tool (IP, server, prefixes, format, symbologies) → wizard (serial, bind) → scan test.
5. Cameras: activate → IP → sub stream → wizard assign → Alarm Server + Vehicle target → drive-through
test → close the browser.
6. Printers: site address → wizard (role, rank) → print a card.
7. Walk-through: button + radar → ticket; QR entry then exit; RFID; a subscriber's plate at the
camera; pay at the booth → receipt → exit; paper reload on each printer while watching the
footer.
8. Record in the site record: every IP, serial, camera password, printer model, which relay is
which, photos of the labels. Remove the temporary laptop addresses. Log out of every device UI.
## Gaps to fill next time you hold the hardware
- Factory address and configuration tool of the **Cashino KP-300H** and the **Rongta RP** units
(both still unknown here).
- The exact screens in `QRCode_v1_6_5.exe` for the reader's IP and server target (a screenshot).
- Whether the camera activation was done with SADP or the browser at park-buzi, and the per-site
camera password location.
- Where the **site record** lives (a page per site under `wiki/entities/`? — park-buzi and park-2
have none yet; the Komodo stack env is the closest thing).

Same printer unit on `park-lab` (real Linux host, booth image stage-2d9bb15, prod compose, dev DB
snapshot with the USB printer as booth-receipt, cards via subscription reprint): paper out → cover
→ reload → reprint — no error. Printer, USB transport and compose wiring cleared in isolation;

park-buzi is shut down (staff shortage). Recorded on [[printer-usb-transport]]: the three

## [2026-09-09] build | K200L printer identified + `k200l` driver with live status; network setup recorded
The bottom label says **Model K200L** (Xprinter/ICS XP-K200L family, USB+LAN, ESC/POS); the LAN
board ("J-Speed Ethernet WebConfig 1.02") calls it "POS-80", as does the USB descriptor. User
configured it from factory 192.168.123.100 (DHCP off, web UI on :80, no auth) to 10.0.10.7 on the
lab; added as booth printer on `park-lab` on the generic driver → badge stayed green with the cover
open, because the generic driver is reachability-only by design. Found the board's status page:
**`/prt_status.htm`**, the Rongta's five rows exactly, but the reply has NO status line/headers
(node:http: "Parse Error: Expected HTTP/"; curl: 000/empty) — so a Rongta-path option would not
have worked. Per the user ("this is not rongta", "create a new printer"): the Rongta driver is
untouched; new **`printer-k200l.ts`** (`k200l`) delegates printing to the generic ESC/POS device
and reads the page over a raw socket, tolerant of both reply shapes; mapping mirrors the Rongta
(unreachable → offline, page not understood → degraded never ready, faults → degraded named, USB →
floor). Tests replay the captured headerless page (10 new, devices suite 76 green); live probe
against 10.0.10.7 → ready; bench with cover open showed "cover open, paper out, printer off-line".
Consequence for park-buzi: over USB the app never saw cover/paper state at all — the reported
"offline" is a probe failure (errno still to be pulled). Pages: new [[k200l-printer]] (names,
network setup runbook, board quirks, status page, park-buzi implication), [[rongta-printer]],
