Keri Doors recommendation for USB Serial Adapter

If you're trying to connect from a Windows 7 machine to a door controller via Keri Doors 4.x, and the serial-to-USB converter that you have doesn't seem to be working, try a Tripp-Lite USA-19HS (get the drivers here).  Some other Keri tips, while I'm thinking about it... the default username and password are both Keri  (case-sensitive), so change them.  The location to modify the associated COM port in Keri Doors is under Setup>System>Network Config>Port (COM 1-4).  Then you can click the Controller Status tab>Status ... which will launch the communication tool, and should report back the "Ctlr Type" and show as "online" in green, if everything is working.  .

This was helpful! Unfortunately, I don't have time to order that specific adapter. I ran over to Best Buy and picked up their Dynex model. I don't see why it SHOULDN'T work, but it doesn't.

I'm wondering if you know what port settings I may need to set under the device manager. It's currently set to 9600 bits per second, 8 data bits, parity "none," 1 stop bits, and flow control "none."

Could changing one of these settings be the magic bullet that will let Doors see through the serial cable?

This was very helpful, thank you! I'm glad to know it can be done.

However, I don't have time to order the model you suggested. I have already picked up the Dynex one from Best Buy. I don't see why it wouldn't work - it installed perfectly, and I have the latest driver.

Could my COM port settings under device manager be to blame? I'm not sure what they should be in order for Doors to recognize the scanner, but they are currently set to:

Bits per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

I haven't even ventured into "Advanced" settings.

Do you have any ideas? Thank you!

I can't remember the details, but I recall having trouble with the random serial to USB adapters I tried. Which is why I we had to order the triplite model. 9600,8,n,1,none also rings a bell... But the trip lite adapter did the trick without any fuss.
