Please note that the Exciter(s) communicates via an RS-485 bus to the PA. In a single drive TX, the Exciter
will be configured with an RS-485 address ID of 80H (as found under the Exciter CONFIG submenu)
corresponding with Exciter A. In a dual-drive TX, Exciter B will be configured with an RS-485 ID of 81H.
Pressing the Exciter A or Exciter B button will bring up a window displaying the Exciter Channel
Frequency as well as the TX System SNR and Upper and Lower Shoulder metrics. Please note: only the
on-air exciter has valid readings.
