emote and Mobile Control Implementation A pilot test configuration (see Figure 12.26) was built around a PC server, con- nected in the Intranet of a "Linksys Wireless-G" router. In order to check its status and configuration, the HTC P3600-PDA runs "vxUtil" [http://cam.com/vxutil_pers.html] tool from Cambridge Computer Corp.

In the PocketPC PDA Build Specification, Deploy aliases file must be selected (see Figure 12.28). As shown above, normal Run-Time Engines that are plugged in PC Internet Explorer (allowing granting remote control of LabVIEW panels) are not a solution for PDA browsers.

Most of the preexisting comparable solutions are highly specialized and propri- etary (e.g., by dedicated hardware-firmware-software of microcontrollers), being not always very affordable. The accomplished configuration is using common PDAs that have a plugged-in micro DAQ card-general purpose and with common inter- face (CF- "Compact Flash"), a high-capacity common memory card (SD- "Secure Digital") and run an universal instrumentation software (e.g., the above-mentioned NI Lab
