E5
Front Panel ON/OFF button Mode
This jumper determines the function of the Front Panel ON/OFF button
If E5 is in the ‘INT’ position, Remote ON/OFF Controls are disabled, Local Controls Only
If E5 is in the ‘EXT’ position, Remote ON/OFF Controls are enabled, Local OFF Control Only
More detail on this function is given in Section XX of this manual
Setting = EXT for all MXi005U transmitters
E6
Transmitter Switching Interlock
This may have either a two pin header or may be permanently jumpered with bus wire
If there is a two pin header, then it requires a shorting jumper
If this is not shorted, then the transmitter will not turn ON.
Setting = Jumper installed

E11
Forward Power Sample Gain
Sets either High or Low gain from the DC sample received from the RF coupler
Set to obtain a voltage between 4.5 and 8V at TP2 for full power RF output
Can be either in the HI or LO position depending on channel and RF coupler
Typical Setting = LO for most MXi005U transmitters

E15
Reflected Power Sample Gain
Sets either High or Low gain from the DC sample received from the RF coupler
Set to obtain a voltage between 4.5 and 8.0V at TP4 for 10% reflected power
Can be either in the HI or LO position depending on channel and RF coupler
Typical Setting = HI for most MXi005U transmitters
