Heavy Duty USB to Serial Converters
With Port to Port Isolation
USR602 & USR604
These industrial grade, isolated, USB to serial converters allow you to add
two or four RS-232/422/485 ports to your PC. Built to rugged specifications,
the USR602 and USR604 offer 2 kV Port to Port isolation. This means that
your upstream PC is isolated from the downstream serial devices and the
downstream serial devices are isolated from each other and the upstream
PC. Additional features such as a heavy duty metal enclosure with panel
and DIN Rail mounting options, high ESD protection, shock and vibration
testing, and wide operating temperatures, make them ideal for use in
harsh environments. Designed for industrial use, they are also suitable for
instrumentation, utilities, and laboratory applications. Full speed (480 Mbps)
USB 2.0 support allows connectivity with modern computer technology.
The serial ports are configurable for RS-232, RS-422 and RS-485 (2-Wire
& 4-Wire). Modbus support enables them to be used with a wide variety
of industrial devices. Each unit comes with DIN Rail and panel mounting
hardware, giving maximum flexibility for your installation.

WHAT IS PORT TO PORT ISOLATION?
Most isolated USB to Serial Converters isolate the upstream
device from the downstream device. This is fine when you
areworkingwithasingleportunit.However,withmulti-port
devices, you need the additional protection offered by Port to Port
Isolation. Simply put, Port to Port Isolation isolates the upstream
device from the downstream devices as well as the downstream
devices from each other. This is the only way you can be sure
