RESERVED MODE CODES ( T/R = 1; 11111)
MESSAGE SEQUENCE (when T/R = 1) = RESERVED MODE CODE STATUS/DATA
(when T/R = 0) = RESERVED MODE CODE DATA + STATUS
For a RESERVED receive Command, the SSRT Mark3 stores the Data Word to the subsystem. If the command was a broadcast, the Broadcast
Command Received bit is set and Status transmission is suppressed. For a RESERVED transmit Command Word, the SSRT Mark3 responds
with Status plus a single Data Word. The Data Word is read from the subsystem.
ERROR CONDITIONS (T/R = 1)
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. Broadcast Command. No Status response. Set Message Error bit (status word), and Command Word Contents Error (BIT Word).
ERROR CONDITIONS (T/R = 0)
1. Invalid Command. No response, command ignored.
2. Command not followed by Contiguous Data Word. No Status response. Set Message Error bit (Status Word), and Low Word Count
(BIT Word).
3. Command followed by too many Data Words. No Status response. Set Message Error bit (Status Word), and High Word Count (BIT word).
OVERRIDE SELECTED TRANSMITTER SHUTDOWN ( T/R = 0; 10101)
MESSAGE SEQUENCE = TRANSMITTER SHUTDOWN/DATA + STATUS
The Data Word received is transferred to the subsystem. No transmitters that have been previously shut down are reactivated as a result of this
command. No other action is taken by the SSRT Mark3. This command is intended for use with RTs with more than one dual redundant channel.
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 Not Followed by Data Word. No Status response. Set Message Error bit (Status Word), and Low Word Count (BIT Word).
3. Command Followed by too many Data Words. No Status response. Set Message Error bit (Status Word), and High Word Count bit
(BIT Word).
4. Command T/R bit Set to One followed by Data Word. No Status response. Set Message Error bit (Status Word), and High Word Count
(BIT Word).
5. Command T/R bit Set to One not followed by Data Word. The SSRT Mark3 replies with Status plus one Data Word. The Data Word is read
from the subsystem.
6. Command T/R bit Set to One and Broadcast Address. No Status response. Set Message Error and Broadcast Command Received bits
(Status Word), and Command Contents Error (BIT Word).
