Does the XStream-PKG RF modem work with Trimle R2 recievers?
Previously used the Trimble Pro 6T receiver.

If it works off of a 3 wire RS232 connection or an RS485/422 serial interface, and can handle some delay, it may work. Just understand that the XStream is an EOL product so there is not much support for it.
