How to create DB9 to RJ45 tunnel adaptor and test

PURPOSE

Procedure to setup a DB9 connector and where to purchase a tester, including how to use the tester on the DB9 connectors on the Micrologic Tunnel Controller Computers as well as how to interpret the results of the test.

PROCESS

DB9 Pin Out Guide

Micrologic Controller DB9 Pin Out:

Isolate the Brown, Gray, White, and Red wires.
Cut the rest of the wires, we will not need them
Grab Brown or Gray wire and insert it into the #2 hole on the head of the DB9
Grab White wire and insert it into the #3 hole on the head of the DB9
Grab Red wire and insert into the #5 hole on the head of the DB9
Attach the head to the body of the the adaptor.

ICS Tunnel Master Jr. Output/Input Pin outs are as follows:

Strip the CAT5/CAT6 cable to see all 4 pair wires
Take Solid Blue wire only and wire it to GND on ICS phoenix connector
Take Brown wire only and wire it to RXD on ICS phoenix connector
Take White/Brown wire only and wire it to TXD on ICS phoenix connector

Testing DB9

Where to Purchase - Amazon Link
The RS-232 Tester that is recommended is the CableMax RS-232 LED Link tester DB-9 Male to DB-9 Female.
NOTE: While other testers are available this article only covers recommended tester.

How to Test

The RS-232 Tester can be used to confirm functionality in 2 ways.

OPTION 1: Plugging the female end into the Tunnel Controller COM Port and plugging the existing DB9-RJ45 adapter into the male end.

OPTION 2: Plugging the female side into the Tunnel Controller COM Port and using a female configurable DB9 plugged into the male end.

If this option is selected, a DB9 loop-back connector must be made from a female configurable DB9 adapter following the referenced configuration below:
Pins 2 and 3 are terminated to each other in a loop.
Pin 5 is seated but is not terminated to anything. End should be taped off for safety.

How to Interpret Results

The results of the DB9 Test can be interpreted base off the following diagrams:

Orange lights are only observed with the DB9 Loopback module (Option 2) plugged in whereas the green lights will be observed when using the in-line method (Option 1).

Anything deviating from the diagrams above is NOT a good result and could be indicative of an issue.

This is an example:
