These instructions will show you how to make a 9-pin serial to Ethernet cable. Serial cables are used to control and configure devices with serial ports. When converting one end to Ethernet, the signal is able to travel farther. When devices are spread out over a large area or placed inconveniently, such as ceiling-mounted projectors, being able to control multiple devices from one spot saves time and money. Only patience is required to make these cables; no prior knowledge necessary. It will take around an hour to complete a cable. After a few practice cables, they can be made in 10 to 15 minutes. With the ability to control devices from a stationary spot, you don't have to worry about searching for a remote or physically pushing buttons on the device.

Required Parts and Tools

Digital Multimeter
Wire Crimpers (Optional)
1 - RJ-45 connector (Optional)
Wire Strippers
Electrical Tape
[1]9-Pin Serial Cable
[1]Ethernet Cable
[2]4-Wire Splice Connectors

Step 1: Strip the Serial Cable

1) Cut the serial cable using the wire strippers, leaving a couple feet on the female end.

2) Using the strippers, remove roughly 2 inches of the cable covering on the cut end to expose the inner wires.
<p>good work....</p><p>I am new at instructables....I made this....Please give me some ideas...</p><p><a href="http://www.instructables.com/id/How-to-Make-Ethernet-Cable-checker/" rel="nofollow">http://www.instructables.com/id/How-to-Make-Ethern...</a></p>
<p>Why not just install a RJ-45 connector on the wires of the D-9 cable?</p>
<p>The title is somewhat misleading. This isn't a serial to Ethernet cable; it's a 9-pin D shell to RJ45 cable with no serial to Ethernet protocol conversion. Which is still useful of course, since some devices (switches/routers is what I've seen) have serial ports with an RJ45 connector.</p>
