my experience with 262 and Integra's are that at least with Trimble and CNH branded ones the Integra does not change the settings on the receiver. If the modem is actively sending CMR into the receiver then I would hook up a laptop with AgRemote and check the settings to see that it is expecting CMR in. Then if the receiver is setup that way everything ought to work. I have not ever had one connected to an AgLeader branded one.
