This compact, isolated USB to RS-422/485 converter allows
you to add a serial port to your USB only PC. The isolated
version, USOPTL4, comes with two kilovolts of isolation and will
protect your PC from hazardous ground loops. The compact size
makes it perfect for field service use but it is also great for
instrumentation and laboratory applications. Full speed (12
Mbps) USB 2.0 support allows connectivity with modern
computer technology.
The serial port is a removable terminal block making wiring
easy. It can handle standard RS-422/485 data rates up to 921.6
kbps.
Each unit comes with 1 meter USB cable and a driver disk.
Drivers support Windows platforms up to Windows 7 in 32 and
64 bit implementations.
The converter comes in two formats - Standard and “Locked
Serial Number.” With the standard format, each unit has a
unique USB serial number. The “Locked Serial Number” format
uses the same USB serial number for all units with the same
model number. The version you select depends on your
application. Standard - every unit is assigned a unique COM
port and a driver must be installed for each unit, ideal
application: fixed locations. Locked Serial Number – Units with
the same model number shares the same COM port. The driver
only needs to be installed once for each model number. Ideal
application: field service.
Our unique “high retention” USB connectors ensure
your cable stays tight. No need for expensive
proprietary cables that lock you in to a single
vendor. They meet Class 1 Division 2 pull force
requirements – 15 Newtons or 3.4 pounds-force –
with a standard off the shelf cable.
