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.
