Use the diagram as a starting point for your installation. Replace the example equipment and cable lengths with your own, and check the connections against your exact model's instructions.
3 m one way
12 V system
Sized against ABYC E-11. The design current is the part's continuous draw. The length is one way; voltage drop includes an equal-length return.
The editable example uses 3.048 m (10 ft) runs unless a shorter run is stated. Metric overviews round these to 3 m. Adapt the parts and lengths to your installation before choosing cable and protection.

Installation notes
Guidance for this model, with sources linked beside the relevant advice.
Verified against the manufacturer's documentation (rev. RUTX11 datasheet v12, ©2025; official quick start and power documentation), checked 2026-10-01. Manufacturer documentation →
This is the standard RUTX11, a mobile router with LTE, Wi-Fi and Ethernet. The manufacturer datasheet, power section, page 11, specifies 9–50 V DC and 16 W maximum consumption. It separately limits railway order code RUTX11 020G00 to 24–36 V; that variant is outside this entry. At nominal 12 V, 16 W corresponds to approximately 1.33 A. This maximum budget is not an idle-current measurement.
The official powering guide identifies the 4-pin DC connector and its supply/ground contacts. The remaining connector positions are digital I/O, not additional power terminals. This catalog exposes only the positive and return of the DC input. Check the device's connector diagram rather than relying on the connector's physical orientation or another router's cable colors.
LAN1 also supports passive PoE, Mode B, 9–50 V, but it is not IEEE 802.3af, 802.3at or 802.3bt PoE. That is an alternative power arrangement, not an output modeled by the two catalog terminals. Do not assume an ordinary active-PoE switch will power it. The reviewed sources do not prescribe an external DC branch-fuse rating; protect the installation's feed for its wiring and applicable supply requirements.
Install in a dry location with room for airflow and antenna cables; the datasheet rates the enclosure IP30, not watertight. Fit the correct mobile and Wi-Fi antennas, insert the SIM according to the official quick-start guide, and follow its first-login and password setup before relying on connectivity. Keep radio/antenna installation within the manufacturer's guidance for the intended region.
Measure supply at the router under load, then check the DC plug, polarity and upstream protection. For network failures, distinguish mobile registration, SIM/PIN or APN problems from loss of power; use the router's status information rather than repeated factory resets. The terminal boundary of 16 W / 9 V, about 1.78 A, is a calculated input-current planning envelope across the specified voltage range, not a separately published connector rating. Energy estimates use 12 V nominal and should be replaced with measurements for the actual radio traffic and accessories.
Build it out
Add RUTX11 standard to your diagram, then connect your batteries, chargers and loads. Crimp calculates cable sizes and checks the connections as you draw.
Every cable you draw there is sized against ABYC E-11, from the same tables as the reference on this page.
Technical reference
Check the model, ratings and connection points against your own unit before choosing installation hardware.
Check stud sizes, fuse type, run length and how warm the space gets against the gear you actually have before you order.
Catalog connection points, current direction and planning limits. Check the manufacturer's pinout and connector ratings before installation.

Method & provenance
Manufacturer specifications describe the equipment. Crimp calculates cable results from the circuit and assumptions you enter.
From the maker
Manufacturer, model, ratings and which terminal does what come from the catalog. A newer revision, or the nameplate on the unit in your hand, can say something different — when it does, the nameplate wins.
ABYC E-11
Sized against ABYC E-11. Boats built to UK or EU rules answer to ISO 13297 — check these figures against it before you build. The run length and the current above are what drive the result. Crimp doesn't know how warm your space gets; draw the cable inside an engine-bay zone on the canvas and it sizes for the heat.
Next step
Open this example as a new project. Add your equipment and cable lengths, then review the sizing and checks for your setup.
