Modular Adapter Black DB9 Female to RJ45 Jack Part 31D1-1740BK

This black modular adapter converts from a DB9 female to an RJ45 socket. By its very nature the pin outs are user configurable to match any needs you may have. The leads are "flying leads" to provide you with more leeway when inserting the pins. A modular adapter is typically used to traverse log distances over a 8 conductor phone line / network cable.
