Two identical Ultra panels are used The left panel is configured as master setup in the mode menu and the right panel is the slave The slave panel obtains all engine and other instrument data from the master panel via the airtalk link RDAC engine monitor and SP x compass or IMU sensor packages are optional components lt is not strictly required that an Ultra system has an engine monitor although most installations do For the above installation the RDAC and tubing for airspeed and altimeter would normally be connected to both systems This makes it possible to change the master slave assignment should this be required For a dual panel layout two distinctly different operating modes can be selected The first is a mode where both panels operate autonomously but will share the same engine monitoring RDAC the RDAC is wired to both panels Also the SP 3 is shared In this mode the only interaction between the two panels is the adjustment of local pressure for the altimeter You can change the pressure setting on any panel and the other will follow The second dual panel mode uses one panel as passive and the other as active panel The active panel transmits all relevant data from altitude and airspeed to engine monitoring data to the passive panel The passive panel does not acquire any data of its own but uses the data from the active panel instead Dual panel modes are setup in the Mode and Units setup menu Page 9 MGL Avionics
