I’ve a power cable for a MAX BR1 Pro 5G for hooking it up to an alternate 12VDC power source. I just realized it has four (4) conductors, not two: Red, orange, brown, and black.
There was no accompanying documentation and there’s nothing in the modem’s user’s manual.
Help?
Hello James,
You can find this information on the manual here. Please check the page 231 and 232.
Also, there small symbols close to the power connector on the router showing each pin function.
Got it! Thanks 
In the meantime I simply tested the connector for the included PSU. Found +12VDC on the +DC In and IGN-I/P pins, -12VDC on the -DC In pin. Then toned-out the power cable.
Should I bond the IGN-I/P (orange) wire to +12VDC (red)? It appears the provided PSU does. (Probably doesn’t matter if IGN-I/P is not Enabled.)
Btw: Might not be a bad idea to add something like “power cable wiring” to that section. I’d searched on such terms and came up with nix.)
Hello James,
you can leave IGN-I/P (orange) unconnected if ignition function is not used.
The input voltage on the IGN-I/P (orange) wire is important only if you will enable ignition sensing function. To enable it go to Advanced → Misc → GPIO. Screenshot from router WEB configuration page is shown below.
In case you install router in a truck, bus or a car you can use IGN-I/P pin to control automatic router on/off once the engine of a vehicle is turned off. This is handy feature to save the accumulator.
For the Peplink team: Adding a bit more to the section, as James suggests, would indeed be helpful. Putting more detail where you show the 4 pin connector that “ignition sense wire need not be connected unless the ignition sense function is enabled in the configuration,” would have been helpful. I only found this detail here in this forum. The extra sentence or two in the manual would help those of us who are resellers, as well as end customers.
Thank you for your valuable suggestion. We’ve revised the ignition sensing part in the user manual. You may find the most updated ignition sensing information at P.231-232 here.
