While the ORIGINAL RB-USB-RIM is a feature rich USB to radio interface module designed to work in even the most demanding radio connections, the new RIM-Lite family is designed to streamline the most popular options into one cost effective module.
Hence, to connect to legacy USB2 interfaces, an eUSB2 to USB2 repeater is needed, boosting the signal to comply with 3.3V IOs required by USB2 interface. PTN3222x is a highly integrated and high performance eUSB2 to USB2 repeater family developed by NXP.
The Basic Hardware Interface. The next step is to be able to interface the RX and TX radios to the SBC. We are currently working on a hardware interface design, but in the meantime an Easy Digi and USB sound card should do the trick. Above is a basic diagram of how this should be wired.
