Connecting QX through USB to Parallel Adapter

[Guest guest]

Could someone please tell me the purpose of the usb adapter?

thanks d

does it have to be used, is it just an extension?

I recently purchased a used QX (White Box) and connected it to my

laptop via a USB adapter. Has anyone had success in using a USB

adapter? I've been told (by the seller) that I cannot hook up the QX

this way and that is why the lights are not coming on and the unit is

not functioning.

I have been using a port replicator (usb to parallel

port adapter) and the lights do not work. I have spent a great deal of

time trying to make them work. I now understand that this adapter was

made so that older printers could be used with newer model usb port

computers. It is possible to connect a QXCI box with the replicator, but

detailed data flows from computer to printer, not the other way around.

All that a printer needs to convey thru parallel port is " yess, I'm

ready for the data, or " no, I'm not ready " .

So the client is receiving signals from your QXCI, but the computer is

only receiving minimal info via parallel port, the rest in subspace. If

your lights are not on, you must also be getting the window that asks if

the client is hooked up properly because the signal is weak.

As has been discussed earlier, " intent is everything " . I have

had good success with no lights on the box. I think your choice is a

financial one. But I look forward to upgrading my computer next week and

knowing for sure that all is functioning perfectly.

Regarding parallel ports:

Bill himself says that if you use a parallel port, one of the pins

has power in it. Thus, you do not need batteries nor the power cable for the

old QXCI. The SCIO is not that way. It requires a power supply externally.

Parallel ports are managed from within the motherboad BIOS (Basic Input

Output System). It is here where you state if the parallel port will be

" bi-directional " or not. The notion that a printer port only sends data is

wrong. True, by setting your parallel port settings to bi-directional it

speeds up the data throughput, it still sends and recieves. Bi-directional

allows the computer to be sending data to the printer at the same time the

printer sends acknowledgment back. Without it, the processes each take

turns. So, if you use a traditional parallel port to connect to your device,

it will be communicating back to the computer. It has to.

Now, the port replicator is another matter altogether. I do not know if it

supplies power to one of the pins in the parallel port or not. Also, I have

never used one so I am not familiar with how to make sure it is set to

bi-directional.

I do know though, that if the printer/qxci/scio cannot return signals back

to the computer, it will not work. And it is pretty much guaranteed that if

they build a parallel port replicator, it is capable of recieving signals.

Printers, harddrives, network connections, serial ports, pretty much any

port in your computer requires acknowlegment from the other end of the

connection in order to do anything.

The QX works perfectly after installing a PCMCIA card with a parallel

port. A USB adapter did not work. Considering MOST new laptops do not

have parallel ports, this is a viable alternative.

If your QX is connected and working, you don't need a USB adapter.

Most new computers lack a parallel/serial port and feature newer USB

ports. The QX requires a 25-Pin cable. I was unable to get a USB cable

with a 25-Pin adapter on the end to work. (I tried 2 separate cables.)

Quantum Life recommended a PCMCIA card with a parallel port and that

worked. :-)
