I planned to use a lot of cheap usb to rs232 converter. I didn't know about console server. They seem very neat! I have only two question:
1- They seem to all use RJ45 i'd imagine that i would use a cable RJ45<->RS232. I found some on amazon, but i don't know if they are standard or i need to look for some specific type of cable.
2- Do they allow the "master" ethernet port to talk to all serial port at the same time? I found some conflitting information about it. If not the usb<->rs232 seem a better solution.
Thank you a lot!
- icedchai 8y ago1) Yes, you will need those cables... The RJ45<->RS232 cables are not standardized. You will need to buy the exact cable, or do some research to make your own: Example: http://pages.cs.wisc.edu/~ajkunen/wiring.html http://pages.cs.wisc.edu/~ajkunen/wiring.html 2) The ethernet port can communicate with all serial ports. Depending on the model, you can program the serial port for PPP, SLIP, telnet, SSH, etc. Back in the old dialup ISP days, we connected modems to these terminal servers and users could either telnet to a host, or initiate a PPP session. And yes, you can basically build your own terminal server with a bunch of those USB<->RS232 adapters.
