Polling

Figure 11-8 Monitor Polling (1 of 2)

Periodically your xPico Wi-Fi will send commands to query information from your serial device.

STEP 1 - STRATEGY

Explore your serial device and determine your strategy for eliciting all of the desired data with the fewest message Commands.

STEP 2 - SETUP

Use Monitor Explorer or directly configure settings in Monitor Poll Configuration. For each message Command, determine an appropriate Timeout and possibly shorten it via a Length and/ or End Character.

STEP 3 - TEST
Testing is rapid and simplified using Monitor Explorer.	Figure 11-9 Monitor Polling (2 of 2)
You can see the serial device response right in your
browser window.

Sample Configuration

Use a single "show" command to elicit the EDS2100 device status.

In Monitor Poll Configuration, set Message 1 Command to "show[0x0d]".

Testing with this, notice that the default Timeout of 100 milliseconds is too fast-we sometimes poll before all the data comes out. So we set Timeout to 200 milliseconds for stable operation.

Note: It is possible to poll with more than one message Command. They will be sent sequentially, and you will define distinct filtering and data mining steps for each.
