Net s Parameter Window If GND contention of two or more pins simultaneously occurs the highest numbered VIP pin takes precedence For example if pin 3 is shorted to GND and pin 6 is then shorted to GND Preset 6 is recalled If pin 3 is closed and then pin 2 nothing happens Preset 2 is not recalled This permits a hier archy of Presets when using VIP pin closures for tiered priority paging Since there are only eight VIP pins you can only recall up to eight Presets using switch closures There are two ways to recall more than eight presets Either use the Drag Net software Recall button which is only intended for the system installer designer or use an Ethernet command from an AMX or Crestron Ethernet equipped product When using Drag Net s Auto Mixer Ducker block you have the ability to link a VIP pin closure to a push to talk switch in a paging or boardroom application When using the Ducker block in these applications the VIP pins act independently provided you Group the appropriate VIP pin with the Auto Mixer Ducker s Input in Drag Net s Remote Map Again see our Drag Net Applications for examples VIP CONNECTION examples for VIP pin 1 pint T REF O a pind gt 20 kQ linear GND GND Contact Potentiometer Closure Level Control VIP Level control Connect a 0 5 VDC source to a VIP pin from an AMX or Crestron card to adjust any or all Level blocks placed in the Processing Map Use Groups in Drag Net s Remo2. the RPM 2m and a computer indirectly using an Ethernet switch Launch the Drag Net application and follow the steps to create a new project and new RPM 2m device configuration Double click the Configure Hardware IP shortcut and follow the instructions to set the unit s IP address to be compatible with your computer s Network settings Tip Ifyou aren t sure what IP to use try the address 192 168 69 69 and subnet 255 255 255 0 This finds the default factory address 192 168 69 22 on the RPM unit without manually setting it WEAR PARTS This product contains no wear parts Now click on the Poll button in the toolbar to find for all devices A device name and IP address should appear under the Live folder in the Project window If a device does not appear consult Drag Net s online Help for instructions on configuring and verifying your computer s Network settings The audio path within the RPM 2m is displayed in Drag Net s Device Configuration window as a collection of blocks wired together to form a Processing Map These maps are cre ated offline as Storage configurations which are then trans ferred to a Live unit Drag blocks from the Palette onto the Processing Map and wire them together to create the audio path Save this file frequently using the File gt Save command Transfer the selected Storage configuration to a Live unit using the Transfer Config button in the Project window A new minty green Device Configuration wind
