Questions & Answers

Is this a true 25 wire DB25 cable? The one listed on Amazon only has 8 wires inside :/

Asked by: inspyre
This cable is a NULL MODEM cable, and only has the 9 wires needed for that connection. If you require all 25 wires, you may have a different pin out and i suggest you contact support for further assistance.
