1. Try to DIY Cisco Console Cable
Cisco Console Cable, Original Cisco Console Cable, needed to connect
Cisco routers, Cisco switches or Cisco firewalls to your PC. What is its
price commonly? Does DIY Cisco Console Cable cheaper and more
convenient and interesting?
Usually Cisco console cable only comes with each Cisco product you
bought. Should be those user who bought a lot Cisco switches and router,
and they only use few to configure their Cisco device.
To DIY your own Cisco Console Cable is cool and can help you save
money, more important, it can improve your ability to make somesmall
kits and accessories by yourself. That’s cool!

2. Beforegetting start to DIY Cisco Console Cable, we should know the
arrangement of the cable.Arrangement on the RJ45 pin and another end
at DB9 port.Let’s have a look at the serial port numbering location 1st
(DB9), and RJ45 numbering location 1st. The following is the port
number for DB9 connector and RJ45 port number:
DB 9 Port Pin Number
RJ45 Pin Number
The color code for Cisco Console Cable as below:
rj45-1 to db9-8
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

3. rj45-7 to db9-4
rj45-8 to db9-7
To confirm the above Cisco Console Cable color code correct, we should
do some verification. Multimeter, mostly people prefer tone mode,
which mean the positive (Red) and negative (Black) touch together, will
hv beep sound from the multimeter.
Mini gender changer, male to male type:

4. We can connectthis mini gender changer to the Cisco Console Cable’s
Serial Port end as shown the picture below:
We 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

5. (as above stated, RJ45′ s Pin 1 connected to Db9′ s Pin
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 we need to get a soldering iron,
and also a female db9 connector.

6. Solder the RJ45 cable to the DB9 Connector according to the cisco
console cable color code above

7. We can get variety of db9 connector which comes with cover, just like as
below. We donot know what this kind of connector call, but it is very
convenient just to have 1 pcs of this DB9 to RJ45 connector.

8. Is it interesting and challenging? Ifinterested, have a try.
