Moxa UPort 1250-G2 is a USB 3.2-to-serial converters that add two serial ports to a PC through the PC’s USB port. Moxa UPort is compatible with both new and legacy RS-232 or RS-422/485 devices. These plugand-play USB-to-serial converters are ideal for mobile, instrumentation, and point-of sale applications. In this series, Moxa improved the LED indicator to a double-sided design for better viewing.
Moxa UPort 1250-G2 Series complies with USB 3.2, 2.0, and 1.1 specifications, and meets the 5 Gbps of Super-Speed USB 3.2. Connecting serial devices to your computer’s USB ports reduces the total cost of ownership, investment in hardware, and long-term management and integration costs. After installing the drivers on your PC, connect the UPort to your computer, plug in your serial devices, and you’re ready to go. Programming is not required, and you do not need to worry about IRQs, configuring a board, power requirements, or connection schemes. Moxa Uport 1250-G2 is compatible with both new and legacy serial RS-232 or RS-422/485 devices.
Common use case is computer system that need to connect different serial devices in the field or need separate interface converters for devices without a standard COM port or DB9 connector. UPort 1250-G2 is bundled with a USB cable that has a latch and screw lock to provide secure connection between the USB converter to your computer. It is compatible with legacy serial devices and can be used with instrumentation and point-of-sale applications.
Automatic Data Direction Control (ADDC) for RS-485
Automatic Data Direction Control (ADDC) simplifies the management of 2-wire RS-485 half-duplex connections, eliminating software interference. Thus, it is unnecessary to write extra code for Windows applications to control the half-duplex protocol. ADDC intelligence is built into Moxa UPort 1200/1400/1600 USB-to-serial converters that support RS-485 serial interfaces.
Automatic Recovery Data Communication (ARDC)
Automatic Recovery Data Communication (ARDC) simplifies the auto recovery of data transmissions even if a cable gets unplugged accidentally. Thus, you do not need to worry about reconfiguring complex settings to ensure smooth data transmissions. If the USB cable is accidentally unplugged, just plug it back into the same port, and the converter will automatically reconnect with the host and continue transferring data. This feature not only reduces reconfiguration time but also the probability of data loss
