CableWholesale DB9 Male/RJ45 Modular Adapter, Gray (31D1-17200)
This gray modular adapter converts from a DB9 male 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
