Introduction
The UPort® 1400-G2 Series USB-to-serial converters are ideal for laptop or workstation computers that need serial port expansion. They are essential for computers which need to connect different serial devices in the field or need separate interface converters for devices without a standard COM port or DB9 connector. The computers also come with a USB cable that has a latch and screw lock for a more secure connection between the UPort and your computer. The UPort® 1400-G2 Series converts from USB to RS-232/422/485. All products are compatible with legacy serial devices and can be used with instrumentation and point-of-sale applications.
