B&B USB to Serial Mini Converters - 1 Port Versions

Add a single RS-232, RS-485 or TTL serial port to your PC

Introduction

These compact USB to Asynchronous Serial RS-232 and RS-485 mini-converters allow you to add a serial port to your USB only PC. They are perfect connecting to a remote device to gather data or upload a program. USB 2.0 compatibility makes installing them on your PC easy. Versions are available with DB9 connectors and Terminal Blocks for quick wiring. We support RS-232, RS-485 (2-Wire) and RS-485 (4-Wire) protocols. Need 5 Volt and 3.3 Volt TTL? We even have a converter for that. Our driver software supports operating systems up to Windows 8 with 32 and 64 bit support. 

USB Cable Included. RS-232 data rates up to 460 Kbps. RS-485 data rates up to 921.6 Kbps.

Locked Serial Number Versions

In addition to the protocol and connector options, you can select between two configurations – “LS” and Standard. To better support field service pools, we created “LS” versions.  Simply put, “LS” stands for “Locked Serial Number.” Units that are programmed with the “locked serial number” are field service friendly in that they all share the same serial number. This feature allows for a single driver installation – if you plug another “LS” version of the same model number into your PC, it will be assigned to the same COM port. With the standard version each time you install a product with the same model number, you must go through the driver installation and it will be assigned to a unique COM port.

Isolation?

In many field service applications, it is a good idea to isolate the serial port from your USB port. If isolation is necessary for your application, check out the popular USO9ML2 and USOPTL4 USB to Serial Converters.
