­­­­­­­­­Micro Seven Inc.® model ER15A, IP Alarm Receiver receives DC-09 compatible digital alarm messages with or without encryption from Contact-ID and SIA-FORMAT alarm panels over Internet and send automation software compatible alarm messages over RS232C. Copyrights Micro Seven, Inc.®, 2012, 2013, 2016, 2017


-Receiving multiple alarm messages in TCP and UDP
-RS232 output

-Compatible with S.G. alarm receiver or Micro Seven formats or output raw DC-09 type message

-Contact-ID alarm message or SIA-DC04(SIA-FORMAT)

-Three different output formats including DC-09 type format, Digital Security Controls’ MLR2E format, and decoded format
 for IP receiver and FXO receiver (optional)
-Instead of using static IP address, use dynamic DNS name for each ER15A
-Encryption using field-programmable 128-bit, 192-bit, or 256 bit key

-Made in U.S.A.




Model ER15A is shown in the above picture.



Multiple TCP and UDP servers


Compatible to ANSI/SIA DC-09 format 2007 and 2013






RS232 interface




ANSI/SIA DC-09 2007 and 2013 for receiving data from your alarm panel

DC-05 digital communication standard (contact-ID)

NIST.FIPS.197 AES encryption standard

Digital Security controls Ltd, MLR2E installation and operation manual


Output formats at RS232 interface by software selectable:

1. DC-09 type format including receiver numbers, account number, MAC address, time stamp, etc.

2. Digital Security controls Ltd, MLR2E installation and operation manual
3. Decoded alarm message format (only for Contact-ID mode)



Programmable key is in 128-bit, 192-bit, or 256 bit. Key and selection of bits in key are programmable by provided software. Received encrypted message must contain “*” character in front of “ADM-CID” to indicate that the message is encrypted. Both encrypted and non-encrypted messages are accepted by ER15A. The replying ACK message from ER15A is encrypted according to ANSI/SIA DC-09 2013. NAK message from ER15A is not encrypted.

Padded data consists of uniform random ASCII characters such as “PPPP” or “????”. The original format is required to be compatible to ANSI/SIA DC-09 2013 format.

Acceptable alphanumeric characters within encrypted data field are in lower-case letters such as “a1c7” rather than “A1C7”.

An example of encrypted message:

The received raw message in the following example without the line feed character in the beginning and carriage return character (0xd):




Please note that the encrypted data starts right after an opening bracket “[“.

After decrypted the above message, the original message is as follows:


9849003E"*ADM-CID"1859R123LABC#4429[#4429|1601 00 129][M0004A3E4A9DD]


The SIA-FORMAT alarm message before encryption:




International AC/DC power adapter.

DC09 Tester-software for transmission of contact-ID and SIA-format DC09 alarm messages with or without encryption from Windows 10.


Number of servers for each ER15A:

TCP: three ports

UDP: four ports



Programming software for IP parameters and encryption key

IP port numbers and DDNS parameters, which designated an external Internet name for each ER15 via Dynamic DNS or other services.

The factory default port number for TCP is 9999 for all three TCP servers, and port 9996-9999 for UDP servers. Multiple UDP servers are not able to be assigned for identical port number.



Power input, 2.1mm jack with center positive

Power requirement: 12VDC @200mA by provided AC/DC power adapter

RS232 connector

Ethernet connector


Unique MAC address


DYNDNS updating feature included with programming software of DYNDNS updating parameters.


Packets receiving:


(CRC codes) “ADM-CID”) (event sequence number)(receiver number)(account pref.)(account number)(alarm events, zone, partition)(MAC address)(time stamp)<CR>


Packet receiving capability from Micro Seven IP alarm panel IP104 or IP alarm panel equivalent EM15:


TCP Socket connection and packet receiving time: less than one second

Number of simultaneous TCP packet reception into three TCP server sockets: sixty alarm panels

Average number of TCP alarm panels that are supported by ER15A assuming 10% of alarm panels are sending packets: six hundreds panels


UDP packet reception: less than one second

Acknowledge packets from ER15A may not be reached to IP alarm panels due to nature of UDP protocols.

Acknowledge packets transmission from ER15A may be disabled.

Number of simultaneous UDP packet reception into each Internet port: twenty alarm panels
