Thank you for purchasing this 2-Port RS422/485 Serial PCI Card. It 

is a universal add in card that connects to a PC or server via 

the PCI Bus, providing high-speed serial connectivity. The serial 

ports are fully compatible with RS422/485  standard by the 

bundled Serial COM port drivers. Each port can be set at any 

mode (RS485 2-wire, RS485 4-wire and RS422) and operate 

simultaneously. 
There is an optional model supports Isolation and ESD 

protection feature. It provides an ideal solution for most critical 

applications.
