Description
The SeaLINK® single-port USB to RS-232 DB9 serial adapter utilizes Sealevel’s expertise in military-grade designs by incorporating a ruggedized, over-molded enclosure into the 2105R. This improves the reliability and durability in industrial and mobile applications such as GPS navigation systems, barcode readers, signature input devices, serial printers, scales, and similar applications.
The 2105R features programmable baud rate and data formats with 128-byte transmit and 384-byte receive buffers. The USB serial adapter is compatible with all standard PC baud rates and supports high-speed communication to 921.6K bps. The 2105R is powered by the USB port and status LEDs molded into the enclosure indicate serial data activity and connection to the host.
Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft Windows and Linux operating systems. After installing the software, simply plug the 2105R into an available USB port and the serial port is recognized as a standard COM port by the host system enabling compatibility with legacy software.
The attached cable is approximately 56 inches long and fully shielded to protect the 2105R from RF and EMI interference that is common in mobile and industrial environments. Standard operating temperature range is 0°C to 70°C (32°F to 158°F), and an extended temperature range of -40°C to 85°C (-40°F to 185°F) is optional.

The 2105R has a DB-9M connector. If you need a DB-25M connector, order the 2101.

Will and Bryant…….the greatest!!
I have always needed tech support for anything I’m doing with computers 🙂 , but this experience far and away tops them all. Microsoft and the rest of the companies with their phony tech support people (they call it customer service—ha ha!) can’t even begin to compare with the effort you guys make. Thank you thank you!! Will and Bryant are off the charts!

Using the 2105R on Natural Gas Transmission Pipeline
I run the RTU lab for a major transmission pipeline co. out of Houston, TX. I determine whether, hardware and/or software will perform as vendors specify. I have found and recommend the 2105R for all USB to serial communications. One of the biggest sell points for me is the Tx/Rx LEDS. This is great when in troubleshooting mode

2105R works great!
2105R USB converter works great when interfacing a computer to a GPS. The unit has no annoying “drops” that we’ve experienced with other converters.

Serial Adapter
After spending many months and paying technicians hundreds of dollars to fix our “communication” problem between our transmitters and our base computer, we tried the 2105R adapter from Sealevel and it has worked perfectly. Wish we would have started with Sealevel first. I rate 5 stars for this adapter and to the company itself.

It has never failed to communicate with any Variable Frequency Drive, Radio, or Programmable Logic Controller I have used it with.
The Sealevel 2105R has been by far the most reliable product of its kind that I have owned. I have
tried other reputable “equivlent” products but every one has failed while attaching to one device or
another. The Sealevel product has never failed no matter what serial device I have
used it on.

High quality and robust
I have had an off brand adapter for a couple of years. I bought the 2105R for firmware downloads through IrDa. It used to take 45 minutes to complete this and with my 2105R it now takes 15. It is a good product that is robust.

USB-Serial Communication
I’ve used many different USB-Serial adapters to utilize older hardware with modern computers with no serial ports. Some work better than others, but this SeaLevel cable blows away all competition with drivers that actually work as intended, LED feedback that reflects realistic functionality, and the correct transposing of the rarely-supported serial lines like DCD. Thanks!

2105R
Used to connect an older weather station to a Acer Aspire One Cloudbook running Linux. The 2105R worked as designed. Great device!
