____________________________________________________________
Advantage of 8 Channels:
Generally, this type of isolator is a much easier installation because the common 9 wire interface
(IBM Compatible) is recreated in full. So the isolator can be plugged in-line with existing cables ,
without the need for rewiring to rearrange or support missing signals.
For Laptops Too !

Instantly isolate laptops and PC's from external influences.
Upgrade the new style low power laptop serial ports to work with classic legacy RS232 signals.
