E. Using the maintenance port for comms and soldering instructions
1. Initially we used for all applications the maintenance port located underneath with the female amphenol
connector underneath the unit to the right of the toggles. It is still a good option as then you don’t need
to open the CT-12K case to communicate with it via a laptop.
2. 1 amphenol connector. ~$40. PT06E-12-8P male from alliedelec.com 800 433-5700.

3. Connect the amphenol connector to the.
Amphenol to serial cable or create a 9 pin to 9 pin cable for the on-site storage if you’re not using the maintenance
port (you don’t need any special serial cables for the Ethernet option)
1. 1 9 pin female serial line connector and cover. ~$2 for connector and
another ~$2 for cover
2. Solder amphenol connector first as there are a number of parts that you
may forget to put on properly
3. Poke with paperclip/pin, the holes in the rubber seal labeled “A”, “B”, and
“C”.
4. Solder beginning with red lead and work up to black. Pic to right is looking
at it from the back where you are soldering
5. Slide/connect all the pieces of the connector
6. See diagram for 9 pin; view is from back where you are soldering
