The poll display HAS TO BE setup in AEDEX mode. You can see what mode it is setup in as power is turned onto the unit. If the mode is incorrect, you will need to run the setup program (T:DATATechmichaelPioneerGuide for Rear Display emulationPPOS31.EXE). Choose the COM port # that the device is on, 40 characters, save to EPROM.
The display uses OPOS drivers for RPRO. They are located at T:DATATechmichaelPioneerOPOS_Driverppos_opos_setup_v10.exe.
