T6T 300 Watt VHF Transmitter Page 126 Maintenance
Virtual Front Panel (VFP)
Virtual Front Panel (VFP) software is supplied on CD and is compatible with any PC or laptop running
Windows 2000™ or Windows XP™. The VFP allows changes to a radio’s settings and channel
information, it displays the current BIT state, displays BIT history, allows security locks to be set, and
provides maintenance facilities.
A radio can be set up using the front panel Scroll/Select switch and LCD, or by using the VFP. Using the
VFP has several advantages over setting the drive assembly from the front panel; these are:
❑ A profile of the drive assembly operation settings and channel information can be created, stored
on disk, and then recalled to download into other drive assemblies
❑ A printout of the drive assembly profile can be made from the VFP
❑ Front Panel Lock is available only when using the VFP. As part of the drive assembly Settings
(see Fig 31), Front Panel Lock can be set to ON. When selected to on, no settings or frequency
information can be changed from the front panel
❑ If the drive assembly is part of a MARC system or operates in a digital mode, a MARC Lock, HDLC
Lock and T1E1 Lock are available when using the VFP. When selected to on, no settings or
frequency information can be changed from the MARC equipment screen, or the digital control
equipment.
