SIA Protocol 2:
The SIA Protocol 1 can not handle certain information in the
SIA level 2 and 3. We now provide the optional SIA Protocol
2 as the following: (option [31] enable)
SRRL[#AAAAAA|EMMZZZZ/MMZZZZ/MMZZZZ][DC4]
Where,
S
: Beginning transmission of the new
SIA protocol
RR
: Receiver number 00-FE
L
: Line number 0-E
[
: Beginning data delimiter
#
: Account ID block code
AAAAAA
: Account ID, maximum sixteen
digits.
|
: Field separator
E
: Function block code
MM
: Event code or modifier
ZZZZ
: Zone code, or user code, or time/
date information
/
: Data code packet separator
]
: Ending data delimiter
[DC4]
: Terminator, 14 Hex
The length of the signal varies, and it can support the
maximum 63 byte data block transmission from the control
panel. When this optional protocol is selected, all SIA
information will be sent to the host computer using this
protocol.
