1150I
1-port RS-232/422/485 USB-to-serial converter with 2 KV isolation
The UPort® 1150I is a USB-to-serial converter with one 3-in-1 RS-
232/422/485 serial port, transmission speed up to 921.6 Kbps, and
15 KV ESD protection. For industrial and commercial applications that
require enhanced reliability, it is also equipped with 2 KV DC optical
isolation protection, providing PCs with both COM port expansion and
protection from potentially damaging electrical spikes. Adjustable
RS-485 pull high/low resistors are built in for daisy-chained RS-485
networks, allowing engineers to connect to any serial device quickly
and easily.
Many engineers use a combination of USB-to-serial converter
plus mini tester to check serial device connections during routine
inspections. However, mini testers are inconvenient to use, particularly
when you need to connect directly through a device’s DB9 connector,
and purchasing mini testers for all inspectors in a factory increases
the overall operating expense. To get around these problems, Moxa
designed the UPort® 1150I, which is an external USB-to-serial
converter with 1 RS-232/422/485 DB9 connector and a built-in mini
tester. The UPort® 1150I has the following features:
• USB 2.0 compatibility
• RS-232 and RS-422/485 interfaces
• Built-in mini tester function
• Built-in modem status LED indicators for easy diagnosis
• Competitive pricing
