Optimising Data Transfer
Great emphasis has been placed on compatibility in the design of this device.
Due to the Ethernet, there are, however, some minor restrictions. Data is not
transmitted in bytes to the network, but Ethernet blocks are formed. This might
result in minor delays. Block formation function does not directly affect the
application but might help to reduce the network load. Some fine tuning might
be necessary for time-critical applications as well. This involves the two timeout
parameters ("Total Read Timeout", "Character Distance").
Block Formation for Serial Data before Transmission into the Ethernet
After the first byte has been received, "Total Read Time" starts. After the time
expires, all characters received so far are relayed to the Ethernet. The default
value is 50 ms.
