HI there,
   We have a suite of remote sites that we connect to hourly using loggernet to connect through IP->NL100->Freewave.  Recently (about 2 months now), following a battery change, we can no longer connect to one of the stations.  
   The station (CR10X) in question is connected to the freewave radio via a MD485.  Currently, if I disconnect the radio and reconnect it the station will connect once, nearly immediately.  After this it is impossible to connect to it.     
  While at this station I can connect through the MD485 to it and two others that are connected through MD485's via the RS-232 port that the radio uses to connect to them.  I have been trying to troubleshoot this with weekly visits and have yet to have success.
  Here are some things I've tried:
1. Replace the serial cable
2. Replace the null modem
3. Reboot the logger
4. Direct connect using  freewave to logger with SC105
5. change the radio
I'm at a loss, any ideas for additional troubleshooting?
