Re: Frozen SDA 5000

Just a run through checklist.

Is the baud rate of the headend unit, and the field unit the same?
(It is possible that if you are in multi-user, and the hub is using 5500 for forward and 5510 for return, that the headend units are set on different baud rates, and that your meter is matched for one baud rate and not the other.   Make sure with the headend group that all their sweep units are operating on the same baud rate.)

Is the headend unit a 5500 operating both forward and reverse sweep?
(If so, make sure that the forward telemetry frequencies are the same (in meter for 5500/5510) and that the sweep mode is in single user)

If the hub is using a 5500 dedicated forward sweep, and a 5510 dedicated return sweep, make sure sweep mode is multi-user, and that the corresponding forward telemetry frequencies are matched to the headend unit(s) configuration.

Is the 5500's forward sweep plan loaded with every sweep point possible enabled?
This can cause, at the least, slow forward sweep, especially at a low baud rate.

Having the headend units channel plan and all associated sweep points built into your channel plan is not required.  The headend unit sends instructions to the field unit as to what frequencies that the sweep points are located on, and tells the field unit to sweep those points.  This applies to both forward and return sweep.   Headend unit calls the shots, and your meter obeys.

It seems that the most likely problem is mismatched baud rates between the particular headend unit, and your field unit.   It is likely you are matched with the baud rate of the 5510, but that the baud rate of the 5500 is set differently.  Try changing the baud rate on your meter while in forward sweep mode, and see if you connect.   I would have HE group look into that, and match the units on their end, or you will be spending alot of extra time switching baud rates in your meter from forward sweep to return sweep.

Hope this helps!
