Provisioning the Input Reference

Sample Command

ED-SYNC::PRS:TS1000::PRIORITY=2;

ED-SYNC::INP1:TS1000::PRIORITY=2;

ED-SYNC::INP2:TS1000::PRIORITY=2;

These commands set the PRIORITY for each input to the same value; if you also provision the QLEVEL to the same value, then you set up a non-revertive switching strategy.
