Meet the Brainboxes 8-Port RS422/485 USB to Serial Multi Drop Hub — a high-performance USB-to-serial solution engineered for multi-bus environments where multiple serial devices must connect to a single host. This compact hub multiplexes one RS422/485 serial port eight times, delivering reliable, scalable communication for data acquisition, industrial automation, and embedded system projects. Designed to maximize throughput without compromising reliability, it’s the ideal answer when you need to expand serial connectivity on laptops or PCs without juggling multiple adapters.

  • Eight RS422/485 serial ports multiplexed from a single USB interface, enabling scalable multi-device communication while keeping your desk tidy and your host software simple.
  • High-speed data transfer up to 921,600 baud per channel, ensuring fast, real-time data exchange for demanding serial applications and time-sensitive control tasks.
  • 128-byte transmit FIFO and 256-byte receive FIFO per channel to smooth out data bursts, minimize latency, and reduce the likelihood of data loss in busy networks.
  • 1 Mbit line drivers provide strong signal integrity across longer cables and noisier environments, delivering dependable performance in industrial and laboratory settings.
  • Plug-and-play USB connectivity with a compact, rugged form factor designed for use with a laptop or PC, whether in the field, in the lab, or on the production floor.

BULKY & BUCKLING HANDLES
Color: Tan
The handles are bulky, and the leather buckles where you normally would hold it which is very uncomfortable. If you try to use the shoulder strap, the handles don't come off and get in the way when holding the purse against your side. Unfortunately, I first used it well past the eligible return date. I'm so disappointed. I would not recommend this product.

easy to access interior with many different pockets
Color: Desert
The back pack is awsome. It's soft, elegant and fits a lot of items...can be used in lieu of small carry on. I liked the openness of the interior area. The inside utility clear pouch was only 1 pouch, not 3 like the video. But I like it better with 1 pouch which leaves me options for larger items. The shoe pouch can be used for other items instead of shoes, if your interested.
