3-11 EEPROM CLEARING.
If a POST failure was caused by a corrupted EEPROM
(Interface Status TE:EEPR), send the
!
command to clear
the entire EEPROM to default values. This will cause the
remote interface parameters to revert to the factory defaults
which may be different than those that were selected from
the front panel. In this case, the remote interface may
become inoperative, and the desired remote interface
parameters will have to be re-entered from the front panel.
The factory default remote interface parameters for the
serial interface are as follows:
Address
000
Baud Rate
19,200 bits per second
Bits
8 bits, 1 stop bit, no parity
Bus Type
RS-232
Bus Sharing
enabled
For units configured with the IEEE-488 interface, only the
address parameter is significant.
Signal Presnt This bit mirrors that status of the squelch. If the squelch is open, this bit is set true.
Fault
This bit mirrors the status of the front panel FAULT annunciator.
Local Control When true, this bit indicates that the front panel LOC/REM switch has selected LOCAL operation, overriding
the remote control bus.
Power on Wait
This bit indicates that the receiver has failed the Power-On Self Test and is waiting for a front panel key
press or the remote control ! command.
Bad Msg
The last command message was not recognized as a valid command.
Bad Value
The last command message was recognized, but contained an out of range numeric value.
SRQ
The receiver is asserting the SRQ message on the bus when this bit is true.
