Hi Digi forum,
We have using the XTend modems since 3 years ago, with great results. But now we see a strange behavior in a new project, which is a simple point-to-point scheme:
-we have 2 points to be communicated via a wireless link (using the XTend modems)
-each point has a Xtend modem, which has been configurated in transparent mode and works with a 1-watt output
-each point has a Controller card
-on point called “A” is the “master”, and the second point called “B” is the “remote”
-the point B is located 400meters/437feet away from point A
They work in this way:
-the point A will send a query to the point B. The point A sends queries every 100ms (miliseconds), and each query is a packet of 20 Bytes length.
-the point B is only waiting the queries from A. So each time the point B recieves a packet from A, reads the packet, extract the query and sends an answer to A.
The problems we have is that this scheme are:
A) we have 70% of queries answered. We think that it must be around 99% because the 2 points are close
What do you recommend us to check or verify to improve this communication link?
B) we have used the XT09 (old xTend model), with 70%.
Which settings do you recommend for this scheme?
C) We also tried to use the XTP9B (new xTend model) with the same results 70%, but sometimes the new modems are blocked and requieres a reset (turn-off and turn-on).
Which settings do you recommend for this scheme, with XTP9B?
