Optional Message Arguments
Arguments are not required for all messages. Arguments are ASCII codes for the characters 0 to 9 (ASCII codes 48 to 57), period (ASCII
code 46) and comma (ASCII code 44).
5.2.5
End of Packet
•
Controller-to-Target – This is the 'Carriage Return' character (ASCII code 13).
•
Target-to-Controller – This is the two-character sequence 'Carriage Return', 'Line Feed' (ASCII codes 13 and 10).
Both indicate the valid termination of a packet.
Serial Remote Control
The ? code is only used as follows:
If the Controller sends an instruction to set a parameter to a particular value, then, if the value sent in the argument is not valid, the
Target will acknowledge the message by replying (for example) with MUT? (with no message arguments). This indicates that there was
an error in the argument of the message sent by the Controller.
The ! code is only used as follows:
If the Controller sends an instruction code that the Target does not recognize, the Target will acknowledge the message by echoing the
invalid instruction, followed by the ! character; for example, XYZ!
The * code is only used as follows:
If the Controller sends an instruction to set a parameter to a particular value, but then the value sent in the argument is valid but the
target is in the wrong mode (e.g., Standby mode in Redundancy configuration or the Remote state is Ethernet Remote (LRS=3)), such
that it will not permit that particular parameter to be changed at that time, the Target will acknowledge the message by replying (for
example) with MUT* (with no message arguments).
The # code is only used as follows:
If the controller sends an instruction code that the target cannot currently perform because of hardware resource issues, then the target
will acknowledge the message by echoing the invalid instruction, followed by the # character; for example, MUT# (with no message
arguments).
