This week we took a break from the engine project as we were awaiting cables in the mail. Monday consisted of running new POS-MV cable and insulated Cat5 cable from both engine rooms to the tech space through the tween deck. This project took some time because the pull stings we ran ended up getting wrapped around each other as one was pulled. The new Cat5 cable is for a new camera in each engine room to be able to see the engines and generators from a different vantage point. To end the day, we made new RJ45 connections for the Wi-Fi router and the clock display. We had to add keystones jacks to be able to create a patch cable to add in as well. The next day we replaced a Cat-5 cable we ran back in June with a different Cat-5 cable because Dennis “preferred the grey color to be structural cable and the green cable to be the patch cable.” That afternoon we learned all about DB-9 and DB-25 connection terminals as well as null modems, which are used to cross over the transmit and receive data line when trying to connect male to male or female to female cords. We used a manufactured R232 serial connection to be able to talk to each other’s computers and understand the concept before we create our own terminal emulation at some point when time allows. On Wednesday Jon, Kyle, and I started the AC wiring project and got as far as we could with the wire we had as we waited for more to come in the mail. Finally on Friday we finished the wiring, and the project was completed. Thursday and Friday Kyle and I disconnected the sensors from the transmissometer and removed them from their mounts. We then put new calibrated sensors and transmissometer into the cage and mounted them accordingly. After Kyle and I put everything back together we connected communications wire up to the transmissometer to ensure that everything was working correctly before we upload the new coefficients into the software.
Friday evening was a crew morale night and we went to Top Golf. It was great to spend time away from work in an incredibly fun environment.
