RAP15_3 018


Model RAP15-3 with Ethernet interface, RS232 interface and telephone line interface are shown in the above picture.


After receiving http command from TCP client for mode 1 for dialing telephone number at telephone line interface and sending Contact-ID message or mode 2 for sending DC09 messages to alarm receiver:


Mode 1 as a telephone dialer: The following http command is required at Internet browser:


Format is as follows:

http://(IP address of RAP15-3)/(PIN)&t1=(primary telephone number of central station)&t2=(backup telephone number of central station)&c=(contact-ID message)




Dialing telephone numbers are primary telephone number after “&t1=” and back-up telephone number after “&t2=” character string.

Contact-ID message is after “&c=” character string. Checksum character at the end of contact-ID message is not needed in the http string because RAP15-3 prepares a correct checksum for message transmission.


The reply message to the client is as follows:


Dialer command accepted

The status inquiry command is required to find whether alarm message is delivered or not.

The command format is:


http://(IP address of RAP15-3)/(PIN)&telstatus


The reply is one of the following:

1.      IP or Telephone Dialer Busy or unacceptable command

It indicates that the telephone dialer is either dialing or sending message to alarm receiver.

2.      Message Success

3.      Call Failed


Mode 2 as an Internet client function for opening a socket for distant DC09 IP receiver/server and transmit DC09 type messages to the server


Format is as follows:


http://(IP address of RAP15-3)/(PIN)&mode=(0 or 1)&ap=(account prefix)&i=(IP address)&p=(IP port number)&c=(contact-ID message)


Contact-ID message is after “&c=” character string. Checksum character at the end of contact-ID message is not needed in the http string.


“&ap=” is a header string for account prefix.

“&i=” is a header string for IP address of IP receiver, which is not RAP15-3.

“&p=” is a header string for Internet port number of IP receiver.

“&mode=0” for SIA DC09 2007 specification, “&mode=1” for SIA DC09 2013 specification

&c=(contact ID message)



The above example is shown with DC09 2013 mode, account prefix of AAA, receiver/server IP address of, IP port of 9999, contact-ID message of 442918160145678, and RAP15-1testing7 as the message ID field.


The reply message to the client is as follows:


1.       Message Success

2.      Call Failed
