Lobaro USB Config Adapter
The Lobaro USB Config Adapter connects the configuration UART of Lobaro devices to a computer for local configuration, diagnostics, and firmware updates.
The adapter does not power the connected device. Always power the device externally during configuration.
USB Adapter V4.2
The USB Adapter V4.2 is the current generation and the recommended choice for new deployments. It ships with a USB-C cable, a 14-pin ribbon cable for Gateway V4 devices, and a 6-pin JST cable for older Lobaro devices (V3 and earlier).
Order code: 1201193
Driver & Installation
The FT231 USB-to-UART chip is natively supported by Windows, Linux, and macOS, so no driver installation is usually required.
If the adapter is not recognized automatically, download the FTDI driver from https://ftdichip.com/drivers/.
