Re: FTDI USB-to-Single Port Serial Adapter

1. The old adapter is probably fine, except for a flaky USB connection. Try a new USB cable with the adapter, if possible.

2. FTDI Serial-to-USB chips all have an electronic serial number that the PC driver can read. This is how FTDI adapters always get the right COM port number assignment, regardless of what USB port they are plugged in to. FTDI is the only Serial-to-USB chip maker that I am aware of that does this. However it is most likely that unless you manually overrode that COM port assignment in Device Manager, your new adapter has most certainly been assigned a different COM port number than your old adapter.

I hope this helps.

Hi Tom,
Yes it is a FTDI version. It is absolutely identical to the old one. Same make same everything. When I look in the Devises Manager then Ports It is showing no problem. It is the same port as the old one.
The system is telling me that it is functioning correctly but it will not connect to the mount.
If I put the old one back on I can connect to the mount no problem but this one is faulty after many year of service. It doesn't always sent the signals to the mount.
Thanks for your help.
