Siretta SL500 solutions are intelligent modems which have been designed to connect remote equipment over a TCP/IP connection to a central location using RS232 serial. Very little knowledge is required to setup and configure the SL500 solution.
The unit can be setup to operate out-of-the-box and configured remotely via the SirettaLINK management portal. Device profiles can be created and tested before mass deployment and specific SIM details and account ownership can be assigned via the SirettaLINK configuration tool.
The configuration of the SL500 solution is managed and controlled directly by users using the SirettaLINK management portal.
The management portal provides advanced validation of all configuration parameters and provides feedback to help reduce configuration errors.
“Centralised device management allows control from anywhere at anytime”
The SL500 solution deals with all common cellular network issues and maintains a robust and reliable connection to the LTE cellular network. This enables a consistent communication channel to your remote equipment.
The units are configurable as a TCP dial-up client using either static or dynamic IP SIMs or alternatively as a TCP dial-in server device using a static fixed IP SIM card. This offers the most flexibility to gain access to information on your remote equipment and provides the most cost effective solution with regards to providing a cellular tariff to suit your entire estate.
Siretta SL500 solutions can also be used to internet enable new and existing equipment without any need for complicated product development or the need to understand complex software protocols or learning new applications.
In addition there is no need to learn complex and specific AT commands to force the modem to implement the required functionality.
The SL500 units work out of the box and can be installed immediately in to you application once you have tested the operating process in a sandbox test environment.
The SL500 solution can be setup simply using pre-built device profiles and uses a secure, dedicated transmission channel to transmit information from your remote equipment to a central location to record, log and control the target application.
The Siretta SL500 solution enables remote access to all of the interfaces in your target application and can enable you to query a host of sensors, processes, power usage and any number of other important parameters.
The SL500 solution detects the cellular network provider and can automatically configure the APN network settings for the connected network eliminating the need to enter any network specific details (only for TCP dial-up client mode).
The primary profile settings required to establish a remote communication channel include the following parameters:
- SIM APN Details
- IP address / Domain of the customer server
- Listening TCP port on the customer server
- Serial parameters (Baud rate, Character framing, Flow Control)
Once these settings are configured the unit will establish and maintain a connection to the server once there is data available to be sent. Alternatively you can configure the device to maintain the connection permanently using client maintain.
In the event of the network dropping a connection, the unit will attempt to reconnect to the server and the software employs a number of techniques to ensure a permanent, robust and reliable connection.

SirettaLINK Standard Features
Encrypted End to End Data Security
End-to-end data encryption (E2EE) secures the communication channel between the SirettaLINK devices and the centralised management portal. All data transferred between the two locations is secured and this ensures that any sensitive information remains hidden within the SirettaLINK system. The cryptographic keys used to encrypt and decrypt the messages are stored exclusively on the endpoints.
TLS Secure Website Traffic
SirettaLINK uses Transport Layer Security (TLS) cryptographic protocols to provide communications security over the internet. The SirettaLINK website uses TLS to secure all communications between the servers and the client web browsers.
Powerful Embedded ARM Processor
The powerhouse behind the SirettaLINK hardware is an ARM Cortex M4 multithreaded processor.
This processor provides control to all of the SirettaLINK hardware interfaces and makes intelligent decisions in real time to maintain a reliable and stable connection to devices in the field, especially in rural or lower coverage areas of the mobile network infrastructure.
Over the air software updates provides the ability to remotely fix issues and automatically keep the SirettaLINK application up to date with the latest features and enhanced application improvements.
Intelligent EDGE Cloud Computing
EDGE intelligence reduces centralised application processing and decisions can be made quickly without requiring the central server to authorise transactions.
This increases the speed of operation, reduces server load and reduces network traffic which in turn reduces cost.
Device intelligence also allows the application to only send the required data back to the corporate application server by filtering out unwanted data at the cloud edge.
