1. Introduction
The Industrially Isolated 3-Port/6-Port USB to RS-232 adapter features 2.5kV isolation to ensure 3/6 serial devices
by DB-9 port connected require long range or multi-drop capabilities won’t be damaged between the PC and serial
applications. Simply installs the drivers, connect the 3-Port/6-Port Serial adapter to your computer, plug in your
serial devices, and you’re ready to go. Programming is not required, and you do not need to worry about IRQs,
configuring aboard, power requirements, or connection schemes. Additionally, the isolated adapter is bus-powered
to eliminate the need for an external power adapter or wall outlet.
The Industrial 12-Port USB to RS-232 adapter features to ensure 12 serial devices by DB-9 port connected require
long range or multi-drop capabilities won’t be damaged between the PC and serial applications. Simply install the
drivers, connect the 12-Port Serial adapter to your computer, plug in your serial devices, and you’re ready to go.
Programming is not required, and you do not need to worry about IRQs, configuring aboard, power requirements,
or connection schemes. Maximum 48 serial devices can be connected under cascading 4 units.
