loop-sense operation. To exit a blocking state after issuing
CONFigFl0 to a blocking radio, the radio must be power cycled.
A radio is not forced out of blocking if the loop sensing has
determined that it should be blocking. The user can issue a PN
code change (locally or remotely) that will accomplish this on the
next 4 loop sense cycles.
While blocking, no AUI commands can be issued. The radio
cannot be queried from the AUI. But commands can be issued
remotely, although the responses will NOT be sent back since
transmits are blocked (as are downloads, other than the loop-
sense packet itself). Acknowledgments are not blocked so re-
transmission of the remote command will not occur if it is a good
RF link.
If turning on a radio will cause a loop, then the last radio
powered up is guaranteed to go into blocking state. If the loop is
made with a wire connecting two radios already powered up, one
of the radios will enter blocking but there is no telling which one
it will be.
f) Professional Addressing Mode. This mode allows improved
duplicate packet filtering in the case of a poor link. It keeps track
of the last packet sent from each of the other M10IIs in the
network (up to 32 M10IIs can be supported in this version).
Normally, when this mode is not used, duplicate filtering
operates on the last packet received. If there are several radios
with a poor link, there is some probability that the normal
duplicate filtering will be inadequate. In this case the
professional addressing mode can be used. This operation
requires that RF IDs (1-32) be entered for all the M10IIs in a
network. The IDs are entered using configuration frames.
Therefore it is considered the “professional mode” because a
professional installer is more likely to use it.
2. An additional feature is the ability to turn off the AUI-port flow control
if the RF link deteriorates. This way, a bad RF connection (for
example, if someone should shut off the remote M10II) will not reduce
the throughput on the local segment. This setting is a ratio of good
transmissions to bad transmissions that the user sets. If the user sets the
