MENU TEXT
FrameSync Status

OK = Valid message structure and synchronization
FAIL = Synchronization has been lost
Absent = 2nd Rear port board is not fitted
Unavailable = Hardware error present
Message Status
Indicates when the percentage of received valid messages has fallen below the 'IM Msg Alarm Lvl' setting within the alarm time period.
OK = Acceptable ratio of lost messages
FAIL = Unacceptable ratio of lost messages
Absent = 2nd Rear port board is not fitted
Unavailable = Hardware error present
Channel Status
Indicates the state of the InterMiCOM communication channel.
OK = Channel healthy
FAIL = Channel failure
Absent = 2nd Rear port board is not fitted
Unavailable = Hardware error present
IM H/W Status
Indicates the state of InterMiCOM hardware
OK = InterMiCOM hardware healthy
Read or Write Error = InterMiCOM failure
Absent = 2nd Rear port is not fitted or failed to initialize.
Loopback Mode
Setting to allow testing of the InterMiCOM channel. When 'Internal' is selected, only the local InterMiCOM software functionality is tested,
whereby the relay will receive its own sent data. 'External' setting allows a hardware and software check, with an external link required to
jumper the sent data onto the receive channel.
During normal service condition Loopback mode must be disabled.
Test Pattern
Allows specific bit statuses to be inserted directly into the InterMiCOM message, to substitute real data. This is used for testing purposes.
Loopback Status
Indicates the status of the InterMiCOM loopback mode
OK = Loopback software (and hardware) is working correctly
FAIL = Loopback mode failure
Unavailable = Hardware error present.
INTERMICOM CONF
This column is only visible if the model number supports InterMiCOM and second rear comms board is fitted.
IM Msg Alarm Lvl
Setting that is used to alarm for poor channel quality. If during the fixed 1.6s window the ratio of invalid messages to the total number of
