UL: cbFlashLED()

These functions cause the USB LED on a Measurement Computing USB module to blink, and the LINK LED
on a Measurement Computing Ethernet module to blink.
When you have several USB modules connected to the computer, or Ethernet modules on the network, use
these functions to identify a particular module by making its LED blink.
Establishing and requesting control of an E-PDISO16
Through InstaCal, you can configure the system to automatically attempt to establish control over the
E-PDISO16 when an application starts up. To do this, check the "Try to acquire ownership on application
startup" option on InstaCal's Ethernet Settings tab. Note that only one computer should have this option
selected; otherwise, two or more computers might compete for control over the E-PDISO16. To manually
request control over the E-PDISO16, press the Request Ownership button on the Ethernet Settings tab.
Only one computer can establish control over an E-PDISO16 at a time. Additional computers that contact the
device can only query the state of the device and its ports. The name of the computer with control over the
E-PDISO16 appears in the Device Owner property on the Ethernet Settings tab.
