RLForwarder (Receipt Lines Forwarder) is a .NET 4.7.2 console application designed to forward sales transaction data from a POS (Point of Sale) system to CCTV cameras or NVR (Network Video Recorder) systems utilizing the OPEN Intelligent Security Application Programming Interface (ISAPI). ISAPI is a text-based RESTful protocol that operates over HTTP, facilitating communication between various security devices and servers, such as cameras, DVRs, and NVRs.
- Captures and processes sales transaction data transmitted via a COM port.
- Transmits processed data to security devices using ISAPI over HTTP.
- Configurable settings via
App.configfor easy deployment adjustments.
- .NET Framework 4.7.2 installed on the host machine.
- A null modem emulator setup with configured COM port pairs.
- Access and credentials for the target CCTV Camera or NVR supporting ISAPI.
Edit the App.config file to tailor the following settings:
ComPort: Specify the COM port for receiving data from the POS.DeviceIP: IP address of the target CCTV/NVR system.ChannelID: Channel ID for the ISAPI overlays.ApiUsernameandApiPassword: Authentication credentials for ISAPI.MaxLinesToSend: Sets the maximum number of transaction lines to send in each API request.
- Ensure the .NET Framework 4.7.2 is installed.
- Set up the null modem emulator for the COM port pairing (https://com0com.sourceforge.net/).
- Deploy the application files to the host system.
- Update the
App.configwith the necessary configurations.
Execute RLForwarderConsole.exe to launch the application. It will start logging both to the console and to the log files in the application directory, detailing operational status and any processing activities.
The application processes incoming POS data, removing unnecessary elements and translating specific terms into a standard format before forwarding to the security system:
- Common POS terms are standardized for clarity and consistency.
- Data lines are formatted to meet the overlay requirements of ISAPI.
