Connecting to Mettler Toledo PS60 Scale, no COM port
Posted on 2012-03-13
We bought a used Mettler Toledo PS60 scale with a USB port, intending to connect it to the shipping manager in QuickBooks Enterprise. I downloaded the manuals for the scale and went through the configuration process to insure the default communication settings were 9600,E,7,1. When I connect it up to my PC, the little beep sounds that Windows has recognized a new USB device.
The manual has a procedure to test the connection using HyperTerm, but therein lies my problem. You have to tell HyperTerm which COM port to connect to, and the device does not seem to get assigned a COM port for me to talk to. I have tried connecting the scale to WinXP-Pro, WinXP-Home and Win7-Ultimate PCs with the same result. I have tried using the AC adapter as a power source versus USB power, and it makes no difference.
Not trusting the serial port drop-down box in HyperTerm, I looked in Windows device manager, and there were no COM ports shown.
Can someone point me in the right direction to troubleshoot this? If the scale is faulty, I should be able to get a replacement, but I was hoping perhaps somebody may have had some experience with this scale and there is something I may be overlooking.
Thanks in advance!
