RS-232 Communications Adapters

Many USB to serial adapters have incomplete or incorrect RS-232 implementations. There are many that we have tested and have found to be defective. The units below are sold be reputable companies that sell good products for RS-232 communications.

Tripp-Lite Keyspan - USB to Serial Port Adapter

The brand that we know works well is the Tripp-Lite Keyspan. We've fully tested this device in a variety of situations and have found that it handles all the important RS-232 lines. https://www.tripplite.com/keyspan-high-speed-usb-to-serial-adapter~USA19HS/

MOXA UPORT - USB to Serial Port Adapter

We trust MOXA for serial device servers (through TCP/IP connection). We have not tested their MOXA USB Uport unit - but it seems similar to the Keyspan and is probably very high quality. http://www.moxa.com/product/UPort_1110.htm

MOXA UPORT - USB to Multiple Serial Ports Adapter

In the MOXA Uport line, you can purchase units that go up to 16 ports through a single USB port. https://www.moxa.com/product/UPort_1610-16.htm

MOXA NPORT - Network to Serial Port

The NPORT 5100 series serial device server is is the only device we trust for creating a serial port through a network connection. https://www.moxa.com/product/NPort_5100A.htm
