------_=_NextPart_001_01C33ED3.B765E71A Content-Type: text/plain James, BNC networks use one pair of wires (coaxial), and rj45 uses 2 pairs (UTP = unshielded twisted pair). I don't bievlieve there are simple converters for this. A common solution for few devices with mixed BNC and RJ45 is this: buy a small hub with enough rj45 ports (maybe some spares...), and one BNC. You can connect all the BNC devices in one chain. for the DB9/RJ45 adaptors: this is used for serial communication lines. there is no electronics in it, just wires from one connector to the other. mostly the rj45 is in fact rj11 or rj12, which have 4 or 6 connections instead of 8. De Vrede, Dirk -----Original Message----- (...) So, I'm just wondering if there are BNC to rj45 adaptors that could help me get this card operational on my network? Any other gotchas involved in trying to mix coaxial and UTP networking stuff? Relatedly, while researching adaptors I ran across some thingies and am just trying to confirm what they are and what they do. These are a plastic housing that covers a plug for DB9 or DB25 ports, and in the housing is an rj45 jack. It looks like these things are made for plugging UTP network cables into serial or parallel ports. Has anyone seen or used these? Can anyone help me understand what they are for? Are they for doing networking via serial or parallel port, as opposed to through a NIC? Thanks for any help in clarifying this dilemma.
