10. Redundancy Controller
Main Menu > Configuration > Redundancy Controller (Ref. Fig. 10)
Online Unit:
XCVR1 (transceiver #1 select)
XCVR2 (transceiver #2 select)
Allows the user to observe or select which XCVR in a redundancy configuration is
currently online or offline. To change the online unit, the trigger should be pressed to
display the two options (XCVR1 or XCVR2). Highlight the desired XCVR to switch
online, and press the (Update) button.
Note: The Online Unit should not be confused with the "Currently Selected XCVR"
selector that is present in several other menus. This is the only menu where the user has
the capability to "force" a XCVR to be the ONLINE or OFFLINE XCVR.
Operating Mode: (Auto/Manual) Allows the
user to control the operating mode of the RSU-
5060 (RED Box). The operating mode selections
are Auto or Manual modes. When in Auto mode,
the RED box monitors the state of XCVR1 and
XCVR2 (A and B). If the ONLINE unit fails, the
RED box will automatically command both the
TX and RX transfer switches to change position.
Note: If the OFFLINE unit is also faulted, no
switchover will occur. Manual mode will not
monitor fault status for automatic switchover. To
change operating modes, the trigger ( ) should be
pressed to display the two options. Highlight the
desired mode and press the (Update) button.
TXWG Switch Status: (Status only). Reports
the status OK/FT of the TX waveguide switch.
RXWG Switch Status: (Status only). Reports
the status OK/FT of the TX waveguide switch.
Controller Voltages: (Status only). Displays the RED
box internal power supply voltages.
(Return) button – returns the user back to the Main Menu and will NOT program any
programmable parameters.
(Update) button – will program the Palm
 device with any parameters that have
changed since the menu was displayed.
