| I have a 2514 Router and I want to use all ports for Ethernet.
I was going to get a DB25 to Serial Cable will that work?
If not, what will I need to do? | |

| Why would you want to do that? | |

Woah. I guess I never thought of it that way. Put the crack pipe down! DB25 typically is serial! EIA/TIA-232 (used to be called RS-232). | |

| I was trying to say going from the DB60 to a AUI connection or RJ45.
I never been too good at remembering the connection thingies | |

| Is the N+ by your name mean Network+?
A+ and Network+ and you don't know the difference between serial and ethernet!

| You can't tell me that you never ask a quesitons about protocols or anyhting network related now that your certified in "everything"! | |

| Are you trying to make a serial port into an ether port? | |
| wirechild 2002-04-26, 5:42 pm |
| I have asked plenty of questions and YES some of them were very stupid. However, I would expect that EVERYONE that has made it past A+ and Network+ would know the difference between serial and ethernet. What good is a cert if you don't know anything? | |
| Taqwus 2002-04-26, 7:09 pm |
| I thought about using it to hook to Ethernet port or computer,(Don't know what type os speeds I could get though, but I could also use it as a serial. If it is cheaper to get converters then to get the DTE/DCE cable I could use a switch as a central location point.
As for wanting to get the DB60 to a DB25 I have the converters to go from that to RJ45 and I can run 2 or 3 Cat 5 cables in the space of 1 DTE/DCE
Also, would you care to enlighten us as to the differnece between the Ethernet and Serial Standards
And remember,
It takes the biggest of us to help, while the littlest of us only can ridicule.
Hope that helped | |

| People usually don't ask quesitns they already know the answer to. | |

| If you were a business owner would want someone working on your equipment and or network that does not know the difference between a serial and ethernet interface. I guess I could use my ISDN port to hookup to my OC3 module just got to find the right converter. Now is that RJ45 or RJ48?
If you get time browse on over to comptia.org and view the exam ojectives and both A+ and Network+ include Serial and Ethernet topologies.
www.ieee.org and www.eia.org | |

| You still didnt anwser the question you just made a referal to someplace else, guess you couldnt remember it off the top your head.
P.S. I searched the Network+ Exam Objectives pdf and the word "serial" doesnt even appear on it
Also, if you would have read my question
you would have noticed that I asked if it was possible to go from one to the other
With all the different type of converters I was not sure if it wasnt possible. I was not sure if you could use an asynchronous serial port to connect to a ethernet port. I didnt even know you could go from USB to Serial till I saw one the other day.
If you still do not understand here is a scenario. I was trying to accomplish something simailar
You have 2 2514 routers
Router 1 has E0 hooked to a 2828, E1 goes to a 1900 and S0 goes to a CSU/DSU, S1 is not used
Router 2 has E0 hooked to a 2828, E1 is unused. S0 Hooked up to a backup ISDN line and S1 hooked up to another CSU/DSU.
You have to hook the routers together by using only a cable. You have only S1 from Router 1 and E1 from Router 2 to use.
How do you solve it, with only using cable/converters
I am curious, are you this abusive to you customers? | |
| mikeghet 2002-04-26, 11:43 pm |
| I am not sure if you can get a converter from eo to so. what I would do if you can is use a serial crossover cable. This will connect to your serial ports of course. It is a dce on one end and a dte on the otherer. IF I remember the one you set the clock rate on is the dce. Of course that is where the dce end of the cable would go into. | |

| Taqwus,
I have been in this business a while, and I can't think of any way that you can possibly connect your S1 to your E1. There are no converters that can do such a thing because the technology is completely different. You need to understand ho ethernet works. Serial interfaces can work with different technologies but ethernet is based on ARPA and MAC addresses while serial interfaces use Frame-Relay, HDLC, and others. | |
| Taqwus 2002-04-27, 11:14 am |
| Thanks,
I guess if you could do that you would just have to get generic modules and convert them to whatever | |

First, did you search A+?
Second, my point was that you still have a ton of learning to do about the very basics before you attempt anything like you asked... I don't think this is the proper forum for explaining ethernet standards vs. serial standards. Try asking your questions in the A+ and or Network+ forums or for that matter even the CCNA forum.
Third, I spoon feed my customers with as much of this stuff as they want to know and are willing to pay for. | |

| A converter dont do this.
To do this you need some kind of bridge. | |
| Taqwus 2002-05-03, 11:12 am |
| Did a search for Ethernet and found nothing on Comptia's A+ pdf
Also, Asking questions (Eventhough they seem "stupid") is a form of learning and is encouraged in every enviorment
PS When you teach something you will remember up to 90% of it as when you read stuff you retain about 20% | |

| I don't know of any way that you could connect a Serial and an Ethernet. I don't think you would find converters to make it either. May be it exists but I haven't come accross it yet.
Your options at this point is getting another router with at least an Ethernet and a Serial. Also you will need a hub/switch. If you could get these 2 devices, you could then set up a connection between the 2 routers you already have. |
