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 
that ground loop or surge can not be transferred through Port 1
to a device connected to Port 2.
