Appendix C. MD485 to RF401 Network
RF401 Configuration
The RF401s may be left in their default settings. However, if there is a
neighboring RF401 network, you should change the Hopping Sequence of
base and remote RF401s to a new setting to avoid interference.
When using MD9 Emulation, after disconnecting from a
datalogger, you must wait for a 40-second timeout before being
able to connect again. NOTE
