Extended Addressing
To explicitly close the channel of A2400 #01:
Command: {01CC
Response: *
The response message is a confirmation that the channel has been closed. A higher level of confirmation can be obtained with the long form:
Command: | }01CC |
|
Response: | *01CC11 | (‘11’ is the checksum) |
The response confirms that channel ‘01’ has been closed.
The same level of confirmation can be used with the Open Channel command:
Command: | {02OC |
|
Response: | * |
|
Command: | }02OC |
|
Response: | *02OC1E | (‘1E’ is the checksum) |
The explicit forms of the OC and CC commands are particularly useful in systems where noise is present in the communications channel and data accuracy is very important. The highest level of data security may be achieved by using parity and command checksums:
Command: | }02CC65 | (‘65’ is the checksum) |
Response: | *02CC12 | (‘12’ is the checksum) |
