CDM-Qx Satellite Modem	Revision 5
Ethernet Management (Base Modem)	MN/CDMQx.IOM

As you can see the MD icon is highlighted as well as the Config. In this case, both the modulator and demodulator parameters are accessible.

If TX icon is selected, only the modulator parameters will be displayed and accessible. If RX icon is selected, only the demodulator parameters will be displayed and accessible.
