OVERRIDE INHIBIT TERMINAL FLAG BIT (
= 1; 00111)
MESSAGE SEQUENCE = OVERRIDE INHIBIT TERMINAL FLAG + STATUS
The SSRT 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.
bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
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 (
= 1; 00110)
MESSAGE SEQUENCE = INHIBIT TERMINAL FLAG + STATUS
The SSRT 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 com-
mand 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.
bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
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 (
= 1; 00101)
MESSAGE SEQUENCE = OVERRIDE SHUTDOWN + STATUS
This command is only used with dual redundant bus systems. The SSRT responds with Status. At the end of the Status transmission, the
SSRT 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.
bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
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 (
= 1; 00100)
MESSAGE SEQUENCE =SHUTDOWN + STATUS
This command is only used with dual redundant bus systems. The SSRT responds with Status. Following the Status transmission, the SSRT
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.
bit Set to Zero. No status response. Set Message Error bit (Status Word), Command Word Contents Error (BIT Word).
4. Zero
bit and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits (Status word),
Command Word Contents Error (BIT Word).
