Using a modem with a cqm1

HI I'am seeking help on connecting my laptop to a cqm1 without a seial port I have tried a USB to seial cable but my usb quit working I do have a 14,400 aswell as a 56K modems ,that have worked with this plc over the phone years ago. but I now want to connect with just a phone cable between either modem and my laptop.

I believe you need a power source to fool the modems into 'thinking' that they are on a real line. I have a unit that I bought a couple years back, for sending files/faxes between computers without having to actually dial out.

It's powered by a 9V battery, and has a male and female RJ11 jack, and if you need, it can be loaned...

PM if you are in the GTA and want it.

The modem will not work without dail tone
Try to use internal phone switch if it possible.

You can purchase a phone line emulator.

Have you done anything to attempt to fix the USB? It is likely a driver problem. You should be able to download drivers etc. from the confuser manufactures website.

Thanks for the info one of the usb ports is broken and now the other one just wont work

As far as the non-serial laptops go, personally I just stick it out with the older laptops. Unless your playing the latest computer games buying an older used laptop might just be your answer. My latest model has a 500mhz cpu, and 3 gig drive. This works fine for PLC programming. These things go out into the field a lot and are subject to damage. I personally dont see the point in investing $2K in the latest and greatest laptop for use in the field.

Just my personal opinion...
