OVERRIDE INHIBIT TERMINAL FLAG BIT ( T/R = 1; 00111)
MESSAGE SEQUENCE = OVERRIDE INHIBIT TERMINAL FLAG + STATUS
The SSRT Mark3 responds with Status and re-enables the Terminal Flag bit in its internal Status register. If the command was a broadcast, the
Broadcast Command Received bit is set and status transmission is suppressed.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3. T/R bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero T/R bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
INHIBIT TERMINAL FLAG BIT ( T/R = 1; 00110)
MESSAGE SEQUENCE = INHIBIT TERMINAL FLAG + STATUS
The SSRT Mark3 responds with Status and inhibits further setting of the Terminal Flag bit in its internal Status Word register. Once the Terminal
Flag has been inhibited, it can only be reactivated by an Override Inhibit Terminal Flag or Reset RT mode code commands, or by Reset. If the
command was broadcast, the Broadcast Received bit is set, the state of the Terminal Flag bit in the internal Status Word register remains
unchanged and Status transmission is suppressed.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3. T/R bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero T/R bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
OVERRIDE TRANSMITTER SHUTDOWN ( T/R = 1; 00101)
MESSAGE SEQUENCE = OVERRIDE SHUTDOWN + STATUS
This command is only used with dual redundant bus systems. The SSRT Mark3 responds with Status. At the end of the Status transmission,
the SSRT Mark3 reactivates the transmitter of the alternate redundant bus. If the command was broadcast, the Broadcast Command Received
Status Word bit is set and status transmission is suppressed.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3. T/R bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero T/R bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
TRANSMITTER SHUTDOWN ( T/R = 1; 00100)
MESSAGE SEQUENCE =SHUTDOWN + STATUS
This command is only used with dual redundant bus systems. The SSRT Mark3 responds with Status. Following the Status transmission, the
SSRT Mark3 inhibits any further transmission from the alternate redundant channel. Once shutdown, the transmitter can only be reactivated by
an Override Transmitter Shutdown or Reset RT mode command, or Hardware Reset (MSTRCLR input). Note that the receivers on both channels
are always active, even when the transmitters are inhibited.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No Status response. Set Message Error bit (Status Word), High Word Count (BIT Word).
3. T/R bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero T/R bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
