Performing a Loopback Test on the Spectre Cellular Router (v2)
Please Note

This procedure will explain how to perform a RS ‐ 232 loopback test using the DB9 to RJ45 cable
(Part Number KD ‐ 2) that comes with your Spectre Cellular Router (v2).

If you do not have this cable, then you can pinout a pigtail using an Ethernet cable. Link to the
cable pinout can be found here


This procedure was completed using model RT3G ‐ 302.

Please power up your unit and connect the KD ‐ 2 to your router.

For this test, I will be using PuTTY. However, you can use any Terminal Emulator Program.
1. Connect to the cellular router’s webpage. If it is still set at default, then the IP address will be
192.168.1.1. Once the page loads, you should be in the General Status section.
2. On the left side of the web page, there is a configuration section. Please click on the
appropriate Expansion port for your router. More specifically, there should be a label on the
back of the router that tells you what expansion module is in what port. For example, the label
on the router I am using for this test tells me port 2 is the RS ‐ 232 port. Thus, I will open
Expansion port 2.
