APPENDIX 3 DIGITAL INTERFACE
AP-8
ACM, ACN - Alert command
ALR - Set alarm state
CUR - Current
DBT - Depth below transducer
DPT - Depth
$**ACM,hhmmss.ss,aaa,x.x,x.x,ca,a*hh<CR><LF>
$**ACN,hhmmss.ss,aaa,x.x,x.x,ca,a*hh<CR><LF>
1 2 3 4 5 6
1. Time (hh=00 to 23, mm=00 to 59, ss.ss=00.00 to 60.99), null
2. Manufacturer mnemonic code (3 digit alphanumeric code), null
3. Alert identifier (0 to 9999999)
4. Alert instance (1 to 999999), null
5. Alert command (A=ACK from ext. equipment, Q=Request from ext.
equipment, O=Responsibility transfer, S=Silence from ext. equipment)
6. Sentence status flag (C should not be null field. Sentence without C
is not a command.)
Information about the use of ACN vs ACM
The alert command sentence formatter ACM is defined in IEC 61924-2 Ed. 1. After Ed. 1 was
released, the ACM is used by other criteria and the IEC technical corrigendum adopted the
sentence formatter ACN to replace the ACM. However, equipment released before the adoption of
the ACN may use ACM. This equipment uses both ACN and ACM.
