CRS-500 1:N Redundancy System
Revision 4
Serial Interface Operation
10–7
MN-CRS-500
# (ASCII code 35)
“#” displays if the Controller sends a command to set a parameter that is correctly formatted, but the modem is not in Remote mode, the
modem will not permit that parameter to be changed at that time. The Target will reject the instruction by responding with this character,
with no message arguments. For example: >0001/BKH#{CR}{LF}.
* (ASCII code 42)
“*” displays if the Controller sends a command to set a parameter to a particular valid value, but the modem will not permit that parameter
to be changed at that time. The Target will reject the instruction by responding with this character, with no message arguments. For
example: >0000/BKH*{CR}{LF}.
~ (ASCII code 126)
“~” displays if the Controller sends a command transparently through the Switch to an attached modem or ODU. In the event that the other
device does not respond, the Switch generates this response. For example: >0100/MGC
∼
{CF}{LF} indicates that the Switch has finished
waiting for a response and is now ready for further COMMs.
10.2.5.6
Optional Message Arguments
Arguments are not required for all messages. Arguments include these ASCII codes:
•
Comma “,” (ASCII code 44)
•
Period “.” (ASCII code 46)
•
Characters “0” through “9” (ASCII codes 48 through 57)
10.2.5.7
End of Packet
•
Controller-to-Target:
This is the Carriage Return character {CR} (ASCII code 13).
•
Target-to-Controller:
This is the two-character sequence of Carriage Return and Line Feed {CR}{LF} (ASCII codes 13 and 10).
This pairing shows the valid end of a packet.
