Rj45 to serial connector not recognising printer

Hi there,

You should have a DB9 to RJ45 converter in the box. This converter is used to change from DB9 serial to RJ45, which is the port on the DSR that is used to connect to the serial console.

Should you do not have such connector, call Avocent Tech Support, they will help you to get that converter.


The NullModem Cable might also be requiered


Also remember:

9600
8
none
1
none

Kindly post more of your details like:
OS (win 7; vista; or xp)
Anti-Virus (norton; mcaffee; etc...)
based on your problem theres a possibility that the printer is not yet connected to your network or something is blocking it from being detected. have you urgent so call now our technician and fir your issues.

This is for a newbridge or alcatel 3624 mainstreet channelbank - do not use the modem side, only use the terminal side - all is needed is Rx, Tx, and ground - if looking from the "window" side of rj45 connector, or pins-side up on rj45 socket.

Nowadays most routers come with RJ45 connectors. That is a connector for network cable.
You might be talking about a serial port, found on many security systems.
If you want to connect the security system, you need a serial cable to connect the security system with your computer, and thru a specialized software (more certain provided by the security equipment, be able to perform the task you have in mind.

If you have a BackUPS CS, you are probably either using it with the USB cable that is supplied or with the 940-0128A supplied by APC, which permits running the UPS in dumb mode. By building your own cable, you can now run the BackUPS CS models (and perhaps also the ES models) using smart signalling and have all the same information that is available as running it in USB mode.
The jack in the UPS may be easily use a 8 pin RJ45 connector. It is easy to construct the cable by cutting off one end of a standard RJ45-8 ethernet cable and wiring the other end (three wires) into a standard DB9F female serial port connector.

i have same problem on my motherboard and it is due to damage, check and see if your RJ45 (lan) is disabled in the system bios.then see if you are not drawing more than 500ma on the usb. good luck!

without the port you cant connect
