Remote Control Device Overview
Fault History (FH) Commands
Entering the query command
FH displays the fault history log.
The TDR7 saves all faults in the fault history log. Whenever a fault is
detected, it is stored in volatile memory until one of the following
events occur:
■
The TDR7 power is turned off
■
The TDR7 is reset
■
You clear the fault history log by typing
FH_0
.
Faults stored in the fault history log are displayed in ASCII string
format beginning with a time tag followed by a functional block
designator that identifies a major operating component of the TDR7
and ending in a fault descriptor. For example, if the input source to the
video decoder is interrupted or disconnected, the RCD displays
15:23:17 day 21 VD FIFO Idle
after you enter
FH
.
If the fault history log has been cleared or no faults have been logged,
the RCD displays
fault log empty...
after you enter the
FH
command.
The functional block designators and the fault descriptors are defined
in Chapter 6 of this manual.
