Question about Magma PCI DMA Serial Adapter

1 Answer

No output from serial ports

I have a problem which randomly appears. I have an ISDN terminal adapter connected to the serial port. This will work completly fine, then occasionally I get a timeout waiting for DCD, when I monitored the port with a "tap" on the times I get the timeout, it appears nothing comes out of the port. Has anyone else experienced the same or similar, and possible a fix. many thanks rems

This sounds like an IRQ inturrupt issue. Do you have other serial devices on this computer? If so, you might consider removing any other serial devices and see if the problem resolves itself. If it does, you will need to reconfigure one of the devices to another IRQ so that they don't interfere with each other. Dan

Have two computers to connect to a printer. One computer uses a serial the other a parallel port. The printer has only one usb port. Is there a dual cable or adapter available to make the transition?


You won't find a cable or adapter that will allow both computers to connect simultaneously to the printer. This is because the printers would interfere with each other's signals. That said, adapters are available, but not cheap. Again, the problem is the language that each type of connector uses is different. On top of that, chances are that the printer software would not allow you to select a serial port output on the printer knowing it does not support serial port interface. Same issue with the parallel port. You apparently are using very old computers if all you have is serial or parallel port outputs. You may be able to get a USB card to install in the computer(s) to provide you with a USB interface. This would be cheaper than attempting to get a pair of adapter cables and more likely to work better as well. Often the adapter cables don't work right and will cause slow printing. Also, you CAN get a switching box that can connect two USB computer ports to a single printer.

Printer adapter from serial 25 to usb printer


Frequently the 25pin plug on a PC is a parallel port, not a serial port. Perhaps it is this you mean.

What do i do with my black wire(cable) that came with my calculator, i bought this calculator from walmart


The cable that has terminals like and audio cable is an Input/Output cable. You use it to connect two calculators through their IO ports.
The TI silver cable with a USB end connects the IO port of the calculator to a USB port of a computer.
If you have a TI Black cable (very unlikely) you use it to connect the IO port of the calculator to a Serial port on a desktop computer. Most recent laptops do not have a serial port anymore.

Connecting laptop to phone KX-TA824 not reading COM 1 to connect


Save yourself the trouble and use the USB port :-)

TA's are tricky, I just order a cable for Panasonic from my supplier so I don't pay attention to the pinouts. The cable is a standard DB-9 Female to Female and it fits into my USB to serial adapter from Iogear.

You might just try a USB cable and make sure the serial port parameters are set properly. Change them, or make sure they are 9600,N,8,1 They are programmed in 1.7 of the maintenance console or via the programming phone in system option 800.

If all of that appears proper, it's probably time to look in the device manager of your laptop and make sure your serial port appears. Then, run Hypertrm to see if you can get SMDR. Once Hypertrm works, the Pana software should work.

Lexmark x6150 unalbe to fax phone line is active using dsl


Hey Tony - Did you recently hook this up to the DSL for the first time? This unit is supposedly not able to work with a DSL line.

The fax modem in your AIO is an analog device and cannot be used on an ISDN, DSL, or PBX digital phone service. However, you can connect certain devices to your AIO that let you use the fax function in addition to these digital phone services.

To connect without an unsupported line:
Connect an active telephone cable from the AIO to the telephone wall jack.

To connect with an unsupported line:
If you use an ISDN phone service, you can connect to an analog telephone port (an R-interface port) on an ISDN terminal adapter.
For more help and to request an R-interface port, contact the ISDN provider.
If you use a DSL (Digital Subscriber Line) phone service, you can connect to a DSL filter or router that will allow for some analog (rather than digital) use.
If you use a PBX phone service, you can install an analog phone line for a fax machine.

If this was working on the DSL let me know. I don't know the location but obviously a separate phone jack is the easiest. Let me know. If this helps you fix it you can rate this as fixed. If you are just going to rate this as helpful I'd rather you please not rate it and just add a comment and say thanks for the info.
If you need more help just add a comment and I'll be glad to assist you further. Thanks.
