R2R, Communication Problem
A reason for communication problems in an R2R net can be a faulty link
speed setting.
The data transfer speed must be the same for all repeaters in the R2R net.
Set the speed to 38400 baud.
To be able to set the transfer speed, connect the repeater locally to the
OMT32/PC and start up OMT32 and the repeater.
When the repeater and OMT32 is running, open the link speed dialog box
by selecting the Repeater Network option in the Advanced menu, and
then the Link Speed option.
Verify the data transfer speed:
If the data transfer speed is 38400 baud, then click the Close button.
If the data transfer speed is anything else than 38400 baud, change to
38400 and click the Update button. The repeater must be restarted after
this setting.
Click Yes to let the new setting take effect.
Repeat this procedure for those repeaters which have indicated problem.
