Overview

The UPort® 1100 series USB-to-serial converters are the perfect accessory for laptop computers that do not have a serial port, and are essential for engineers who need to connect different serial devices in the field or separate interface converters for devices without a standard COM port or DB9 connector. The UPort® 1110 converts from USB to RS-232, the UPort® 1130/1130I from USB to RS-422/485, and the UPort® 1150 from USB to RS-232/422/485. All products are compatible with new and legacy serial devices, and can be used with mobile, instrumentation, and point-of-sale applications.
Typical Application—Surveillance Monitoring System

The most basic video surveillance setup consists of a single camera connected directly to a monitor and recording device. However, many businesses require video surveillance on a larger scale requiring a dedicated management system. Existing management systems often lack device-port versatility, making converters a necessity when connecting different devices.  Management systems needing USB-to-serial converters for serial devices such as card readers, modems, video cameras, and sensors, now have a simple solution.  Moxa’s UPort® 1110/1150 converters provide plug-and-play serial device connectivity without having to install new adapter boards, which usually requires opening of computer/server chassis.  Also, a unique driver allows the UPort® 1110/1150 to retain COM port numbers when they have been  unplugged and then reconnected again, even into a new USB port.
UPort® 1110/1150 convenient characteristics include:

    USB 2.0 compatibility
    RS-232 or RS-422/485 interface
    Stability and reliability
    Cost-effective
    Plug-and-play  
    Easy to use
