The S4 Open BACnet N2 router uses male DB9 connectors for its four N2 Bus Ports. These can be connected to the N2 Bus with a standard female DB9 breakout board. N2- connects to DB9 pin 1. N2+ connects to DB9 pin 2
The Field Fail LED Indicates:
- Relay failure in one of the panels
- Panel without configuration – no program
- Driver card failure
Link Fail Indicates:
- Dataline short or disconnected (missing the 24VDC)
- Burned interior ¼ Amp fuse – F1
- Defective unit
At power up the LINK Fail blinks and if the Dataline is clear (24VDC) for 10 seconds, the LINK fail will stop. If there is a BMS controller on-line that polls the network, the Dataline voltage will be below 20 V – which will not allow the LINK to clear. In this case, after a power outage, the BMS interface shall be disconnected till the LINK fail goes off.
RLINK CONNECTOR (RJ45 to DB9)
- Pin 2 – White
- Pin 3 – Blue
- Pin 4 – Black (DTR)
- Pin 5 – Green

The TLC dataline communications system supports multiple access points – RLINKS. Each RLINK supports global programming, monitoring and control of the distributed Lighting Automation Panels. However, to avoid conflicts, only one unit (the “Master”) can broadcast the time of day. CAUTION: In a multiple RLINK system, the 2nd, 3rd, …th RLINKs must be configured as “slaves” by moving the internal switch setting as described below. The Master RLINK is connected directly to the primary operator’s PC – The PC which will be used to set the system clock.
CAS have used 2 Rlinks in master mode successfully
Changing an RLINK from Master to Slave
1. Remove the two Phillips screws in the rear panel
2. Slide the board assembly out of the housing as a unit
3. Move the slide switch in the front right corner to the “Slave” position
4. Position the board in the extruded rails and slide back into place, while making sure the “ALARM RESET” button clears the front face plate.
CUrl and libCUrl is a very powerful library for sending HTTP and HTTPS requests to servers. Building the libraries on windows with Visual studios using the /MT and /MTd flags is non-trivial.
- Download and extract the CUrl source code to a temp directory. http://curl.haxx.se/download.html, in this tutorial we will be using curl-7.37.0
- Open the “Visual Studio Command Prompt (2010)”
- Browse to the Winbuilds folder. \curl-7.37.0\winbuild
- Type “Set RTLIBCFG=static ” in to the command prompt and hit enter. This will set up the compiler to build for /MT and /MTd
- Type “nmake /f MakeFile.vc mode=static DEBUG=yes” to build the debug version or
Type “nmake /f MakeFile.vc mode=static DEBUG=no” to build the release versions
4) Click the “Save” button
5) Click the “Generate configuration File” to download the current configuration from the CAS Gateway.
7) Run Wireshark and click the “Capture Options” button
To compile 64bit code on a 32bit Linux computer you need to add the “-m64″ compile flag to the project settings.
- Download and install FileZilla (or any other FTP application)
- Connect to the CAS Gateway using the CAS Gateway’s IP address as the host. No username or password.
- Browse to the “/history/” Directory
- Download all the CSV files from this directory if they exist.
- Goto the System Action page. http://<ip address>/bin/system/
- Click “Save Database” button.
- This will present you with a XML page that says the action was done correctly.
- Go back to the System Action page. http://<ip address>/bin/system/
- Click “Export the database from the device” link
- This should download a database.db file
- Goto the System Action page. http://<ip address>/bin/system/
- Click the “Generate Configuration File” link
- This will generate the configuration file and redirect you to a page where you can download the newly generated configuration file.
- Click “Export Configuration” after the system has finished generating the configuration file.
This article will describe the steps to use the CAS BACnet Explorer to write to the Out Of Service Property.
1) Open the CAS BACnet Explorer and discover for the device that you would like to write to the Out Of Service Property.
5) Check that the value did change.
We have updated the CAS BACnet Explorer with the following changes.
- Proper parsing of Forwarded-NPDU messages allowing the CAS BACnet Explorer to correctly discover devices behind BBMDs and BACnet Routers.
- Added Cancel Button to all users to cancel long discovers without having to exit and close the CAS BACnet Explorer
- Added Who-Has discovery method.
- Added Time Synchronization functionality. Users can now set the local time of a BACnet device through the use of a Time Synchronization message.
- Can detect if there are duplicate device IDs on the network and provides users information about which devices have the duplicate IDs.
- Numerous bug fixes.
This new version was be released on Tuesday Dec 10, 2013
A 10-serial, 2-Ethernet port, 1 DH+ port protocol translator gateway enables data transfer between serial, Ethernet and Allen Bradley DH+ protocols. An extensive library of drivers provides easy interoperability between a variety of devices used in process control and building automation industries.
The FieldServer is an Allen Bradley DH+ protocol translator/gateway which enables devices using one protocol to communicate with devices using another protocol. An example is a PLC using one protocol needing to supply alarm information to a DCS using Data Highway Plus. In a single, comprehensive package the FieldServer provides the hardware and software necessary for this translation.
The FS-B4013 DH+ gateway includes eight RS-232 ports, two RS-485 ports, two Ethernet (10BaseT) ports, and one Allen Bradley DH+ port to interface to the devices. All the necessary software and instructions for configuration are supplied with the FieldServer. FieldServer Technologies also offers fee based configuration services. Besides Allen Bradley DH+, FieldServer are available for various fieldbuses.
DH+ cables are often called the Blue Hose because of the blue color of the cable made for this purpose. It’s a twisted pair with a shield. The Drained Shield is used for the ground terminal. DH+ is based on RS485 but it isn’t.
Supported Baud Rate: 115.2K Baud rate
DH+ terminal Specification:
Signal- = Blue = Terminal 1 = Terminal closest to white LED
Shield = Clear = Terminal 2
Signal+ = Clear = Terminal 3
A stretch sensor is a cylindrical cord which can be stretched to achieve varying resistances. It’s a sort of variable resistor where the resistance can be adjusted by the intensity of the stretch. Usually when the sensor is stretched by 50% it reaches double it’s initial resistance.
Some stretch sensor applications:
- Various stress measuring.
- Physics experiments.
- Could be used in robotics.
- VR suits/gloves.
- Biometric displacement reading.
- Feedback sensor for air muscles.
