1. The MidiMux is uploading firmware to an MPEG encoder connected to a TS input port This state is reported for a short time during powerup and after changing the TS input mode to MPEG Encoder Loading the FPGA failed This status probably indicates a hardware failure Please ask for support The TS input mode of TS input port x is set to encoder but a MPEG encoder was not detected or an error occurred while starting the encoder Please make sure that your encoder is connected properly or try a different encoder if you suspect a hardware problem The TS input mode of TS input port x is set to tuner but a tuner was not detected or an error occurred while configuring the tuner Please make sure that your tuner is connected properly or try a different tuner if you suspect a hardware problem The TS input mode is set to tuner a tuner was detected but is not locked to a signal Check if your tuner settings are correct and make sure that the tuner gets a good signal The MidiMux is working The MidiMux is in an unknown state This indicates a severe hardware or software error Power cycle your MidiMux and if the problem persists ask for support 6 MiniMod Remote Control The MidiMux is capable of controlling a MiniMod connected to the MidiMux TS output port This means that you are able to control all of the MiniMod s modulation settings from the MidiMux RS232 serial port or display keypad To make the MiniM2.
