Hi
Just having a play with the new features of loggerNet 4.2 and was very interested in the serial port pool. We run a number of phone modems in different groups for speed of polling and though the Pooled option would be a great benifit to provide robustness when a modem or connection fails....
the problem I discovered is that when I combine all the station under a SerialPortPool they only call sequentially?
would it not be favourable to provide calling on all available modems? and only eliminate modems once a failure rate was exceeded? In the current configuration the redundant modems dont actually provide an increase in call capacity and for my applicaion I am better to keep seperate so I can call concurrently.
just a thought..
Hi,
When you configured the SerialPortPool, did you configure one pool with multiple PhoneBases beneath it. This will not achieve what you need. Instead you need to Configure multiple SerialPortPools (each with the same Serial Ports in t the pool), each with a single PhoneBase \ PhoneRemote \ PakBusPort \ Logger etc. This will cause each collection to be able to operate simultaneously up to the number of ports in the pool. i.e. 3 ports in the pool up to 3 simultaneous collections.
If you want an example Subnet for this let me know your email and I will forward one for you.
Note that in Status Monitor, under the Tools menu there are also Pool Statistics and that detail the error rates of individual devices in the pool and statistics as you describe. As this sort of selection method already takes place.
I hope that helps, but feel free to ask any further questions.

Thanks for the explanation, will give that a go
I take it the phone modem device controls the sequence rather than the serial pool
