Peplink 10ft DC Power Cable – 4-Pin to Direct Wire with Ignition Sense (ACW-634)

Hardwire your Peplink or Pepwave router straight into a vehicle or equipment DC power system with the Peplink ACW-634 10ft DC Power Cable. One end has the 4-pin Molex Micro-Fit connector used on Peplink mobile routers; the other end is bare, direct-wire leads ready for your fuse block, battery or power distribution panel. It is the Peplink-recommended way to permanently install a router in a vehicle and to use ignition sensing.

Ignition Sense: Router Power That Follows the Key

The 4-pin connector carries more than just power. Along with the positive and ground leads, it has a dedicated ignition input (IGN) lead and an I/O (GPIO) lead. Wire the IGN lead to an ignition-switched (accessory) circuit and the router knows when the engine is on or off.

• Key on: the router powers up and connects automatically. No buttons to press.
• Key off: the router stays online for a delay you choose, then shuts down cleanly so it never drains the battery.
• Short stops covered: fueling, deliveries and quick stops don't drop the connection, because the router waits out the delay before powering down.

Ignition sensing is turned on in the router's web admin under Advanced > Misc. Settings > GPIO. If you don't need it, simply leave the IGN lead insulated and unconnected.

12V to 52V DC Wiring

The ACW-634 is built for hardwired DC installs across 12V to 52V DC systems, covering cars, vans and pickups (12V), trucks, buses and heavy equipment (24V), and 48V marine, solar, telecom and battery-bank systems.

Important: the safe input voltage depends on your router model. For example, the BR1 Pro 5G accepts 10V–30V DC, while the Transit Duo Pro accepts 12V–56V DC. Please check your router's DC input rating before connecting, or reach out to Crosstalk Mobile if you're unsure.

1. Positive (+): connect to a constant (always-on) fused positive source.
2. Ground (–): connect to chassis ground or the negative bus bar.
3. Ignition (IGN): connect to a fused, ignition-switched circuit. Leave unconnected if not used.
4. I/O (GPIO): optional; leave insulated unless you use the router's GPIO features.

Install tips: add an inline fuse close to the power source, match each lead to the pin labels in your router's hardware guide, and secure the cable away from heat and moving parts. For fleet or commercial installs, Crosstalk Mobile can help plan the wiring.

Frequently Asked Questions

Do I have to connect the ignition (IGN) wire?
No. If you don't need ignition sensing, leave the IGN lead insulated and unconnected and the router will run whenever power is applied.

Can I use this on a 24V truck or 48V system?
The cable can be used across 12V–52V DC systems, but your router must also support that voltage. Check your router's DC input rating, or contact us and we'll confirm before you wire it.

Do I need a fuse?
Yes. The cable has no built-in fuse, so install an inline fuse close to the power source, sized to your router's power requirements.

Which routers does it fit?
Any Peplink router with the 4-pin Molex Micro-Fit power port, including the BR1 Mini, BR1 Pro 5G, BR2 Pro, Transit and B One series listed above.
