5. Serial Solutions Driver Upgrade / Rollback 
There are two parts to the Serial Solutions driver. 
(Taking for example the PCMCIA PM-121 2 port Device) 
•  Card Driver: “Brainboxes Limited – 2 Port PCMCIA 422/485 Card” 
•  Card Driver: “Brainboxes Limited – 2 Port PCMCIA 422/485 Card Port 1” 
•  Card Driver: “Brainboxes Limited – 2 Port PCMCIA 422/485 Card Port 2” 
•  Port Driver: “Brainboxes Serial Port (COM7)

NB: If you need to upgrade or roll back the Serial Solutions driver, we recommend to completely uninstall the 
existing drivers first, and then to install the new drivers from fresh. This will restore all the factory settings to 
default. However, if you instead wish to keep all of your existing settings, you can use the ‘Update Driver’ or 
‘Rollback driver’ in device manager for upgrading/rolling back the Serial Solutions driver. 
5.1. Upgrading the Serial Solutions Driver 
1.  Go to Device Manager and Right click on the Serial Card entry (Found under Multiport Serial Adaptors –

2.  Select Upgrade Driver. This will launch the Found New Hardware Wizard. Follow the on screen 
instructions and point to the location of the new driver package. 
3.  Repeat this for every Serial card and port entry.
