Hello, we shortened the connections of the DVL A-50 by terminating it with a Seacon MCIL8F connector, but the DVL stopped working. We replaced the original cable with a non-twisted pair cable and we are wondering how this affects the communication. The DVL’s communication takes place over Ethernet, but we cannot receive data through the terminal. We have checked the power connections and voltage levels and there are no anomalies. If the lack of twisted pairs causes signal loss, would it make sense to test at a short distance? Also, can missing shielding affect the communication? If anyone has a similar experience or can suggest a solution, I would be grateful if you could share your ideas.
Thank you!
Hi @omer_1 -
Twisted pairs are indeed essential to standard ethernet communications - a section untwisted of any length can induce issues with the high-frequency communications.
Replacing the straight wire used with one that uses twisted pairs should solve the issue - MCBH connectors can typically pass ethernet signals even though the signals will be “untwisted” for a very short distance through the pins of the connectors…
