Do you have any idea how much a pieces of Original Cisco Console Cable? Does DIY Cisco Console Cable cheaper?

According to the vendor ,the Original Cisco Console Cable worth approximate RM100 above (60USD++). Usually Cisco console cable only come with each Cisco product you bought, but I found that ebay just sold at around 5USD to 10USD exclude shipping fees, while local website sold at RM60 above.

Should be those user who bough a lot Cisco switches and router, and they only use few to configure their Cisco device.

I was thinking does any Cisco’s Freak out there custom DIY their own Cisco Console Cable? I guess I am one of the “freak” who plan to do it.

Before I get start to DIY Cisco Console Cable, I require to know the arrangement of the cable. Arrangement on the RJ45 pin and another end at DB9 port.

Let study on the serial port numbering location 1st (DB9),  and RJ45 numbering location 1st. below are the port number for DB9 connector and RJ45 port number:

The color code for Cisco Console Cable as below:

rj45-2 to db9-6

rj45-3  to  db9-2

rj45-4 to db9-5

rj45-5 to db9-5

rj45-6 to db9-3

rj45-7 to db9-4

rj45-8 to db9-7

To confirm the above Cisco Console Cable color code correct, I require to do some verification. I require a Multimeter, mostly I will prefer tone mode, which mean the positive (Red) and negative (Black) touch together, will hv beep sound from the multimeter.

I need to use either 1 end of the multimeter to point to the RJ45’s Pin 1, and another end touching each pin on the DB9 serial connector until the beep tone occur. Record down which pin is come from RJ45’s Pin 1 (as above stated, RJ45’s Pin 1 connected to Db9’s Pin 8)

Repeat the same step for RJ45’s Pin 2 until Pin 8, the result will be as above Cisco console cable color code.

After get known all the color code, now you require to get a soldering iron, and also a female db9 connector.
