If you run into issues step 1 is to make sure the static route is working. Type in the IP address of the JAP device you are working with and ensure the web page loads.

The JAP receivers only typically require 1 setting to be changed.

Log into the JAP device by going to its IP address with your browser then selct the Functions Tab and scroll down to Serial over IP

Select CLI Access and then Apply.

Then go to the System Tab at the top Then Utilities then click Reboot

IMPORTANT: Make sure to set the bottom of the JAP Serial pins to null modem. If you need help with this please contact us.


This is the default pin lay out on the bottom of the JAP receiver. You must move both pins down for the IR Flux too work.

This is how the pins should look after you move both of them down.

Hooking up the flux

Some Flux Kits come with a power converter cable which allows you to use the 5V DC plug on the JAP receiver (when powered via POE) to power the Flux. Others may require the 5V Power supply that is included.
