SELECTED TRANSMITTER SHUTDOWN (10100)
MESSAGE SEQUENCE - TRANSMITTER SHUTDOWN DATA * STATUS
The data word received is transferred to the subsystem and status is transmitted. If the
command was broadcast, the broadcast received bit is set and status transmission suppressed. Intended for use with RTs with more than
one dual redundant channel.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Not Followed by Data Word. No status response. Bits set: message error (SW), High Word Count, Illegal Mode Code (BIT
Word).
3. Command Followed by too many Data Words. No status response. Bits set: message error (SW), Low Word Count, Illegal Mode Code
(BIT Word).
4. Command T/R bit Set to One. No status response. Bits set: message error (SW), Illegal Mode Code, High word count (BIT Word).
5. Command T/R bit Set to One and Broadcast Address. No status response. Bits set: message error, broadcast received (SW), Illegal
Mode Code, High Word Count (BIT Word).
OVERRIDE SELECTED TRANSMITTER SHUTDOWN (10101)
MESSAGE SEQUENCE - TRANSMITTER SHUTDOWN DATA * STATUS
The data word received after the command word is transferred to the subsystem. If the
command was broadcast, the broadcast received bit is set and status transmission suppressed.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Not Followed by Data Word. No status response. Bits set: message error (SW), Low Word Count, Illegal Mode Code (BIT
Word).
3. Command Followed by too many Data Words. No status response. Bits set: message error (SW), High Word Count, Illegal Mode Code
(BIT Word).
4. Command T/R bit Set to One. No status response. Bits set: message error (SW), Illegal Mode Code, High Word Count (Bit Word).
5. Command T/R bit Set to One and Broadcast Address. No status response. Bits set: message error, broadcast received (SW), Illegal
Mode Code, High Word Count, T/R (BIT Word).
RESERVED MODE CODES
MESSAGE SEQUENCE = RESERVED MODE CODE (T/R = 1) * STATUS
RESERVED MODE CODE (T/R = 0) * STATUS
The CT2553 responds with status. If the command was broadcast, the broadcast received bit is set and status transmission suppressed.
ERROR CONDITIONS (T/R = 1)
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No status response. Bits set: message error (SW), High Word Count, Illegal Mode Code (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. Bits set: message error (SW), High word Count, Illegal Mode
Code (BIT Word).
3. Command Followed by too many Data Words. No status response. Bits set: message error (SW), High Word Count, Illegal Mode Code
(BIT Word).
