DAQmxSwitchOpenRelays
int32 DAQmxSwitchOpenRelays (const char relays[], bool32 waitForSettling);
Purpose
Opens the specified relays. If you set waitForSettling to TRUE, this function waits only after opening all relays. If you want to wait for settling after opening each relay, use this function multiple times to open each relay separately.
When you operate relays directly, you circumvent the protection offered channel usage types. Avoid using this function when you use DAQmxSwitchConnect and DAQmxSwitchDisconnect. This function does not pass the changes you make to those functions.
