The host software should attempt to connect to the device's IP and port to verify normal connectivity. I tried connecting it directly to the computer either with a normal network cable or with a crossover cable but the web page doesn't open. Page 47 Communication command2 This command is enabled only when the communication command is enabled. Laureate meters are modular with a middle slot reserved for a communication board, as illustrated in our Laureates Overview web page. Page 60 Block Communication Function for LED Display To display LED data for ASCII display that is synchronized to each digit, set data for each digit and validate this set data by display selection by communication (Communication Number FA65). Use Laurel’s 6-wire data cables CBL03-1 (1 ft) and CBL03-7 (7 ft) to interconnect meters if these lengths fit your application. The board with dual RJ11 jacks is the more popular since is can use commercial straight-through, non-reversing, 6-wire data cables with RJ11 connectors. This section describes the QED-Forth routines that control the RS485 transceiver, and presents some ideas that may prove useful in designing a multi-drop data exchange protocol. This section also defines the logic states 1 (off) and 0 (on), by the polarity between A and B terminals.

The solution is provided by the Laureate DIN rail mounted breakout board, which provides two RJ11 jacks with six screw clamp terminals all wired in parallel. The two jacks are wired in parallel by circuit traces on the circuit board. By using two jacks, up to 31 L485 boards can be connected in parallel for daisy chaining using readily available CBL03 data cables with no need for a hub. In this way, data can be sent back and forth across an RS-485 network. The rest is used to maintain the network passing the token around and looking for new devices. Most vendors implement their devices as masters (ie token passing devices). In the process of development of serial devices there is a necessity of their communication with PC via RS232 ports. Confirm hardware connections including serial port devices, and check if your gateway and energy meter are correctly connected. The program facilitates the development, debugging and analysis of software and hardware solutions that use serial communications for data exchange. If the serial port terminal device receives data but does not respond properly, monitor the data from the serial port device. Confirm serial port parameters such as baud rate, data bits, and stop bits: Baud rate should be configured according to the connected RS485 device, commonly used rates are 9600 and 115200; Refer to the device manual or contact RS485 device technical support for configuration, especially if set to Modbus mode, confirm if the function code matches.

Contact Tech support for helpâ¦. Enron Modbus - another extension of standard Modbus developed by Enron with support for 32-bit integer and floating-point variables, and historical and flow data. The serial bridge Data View visualizer has two panes. This makes our product, in fact, the only nonintrusive software serial protocol analyzer on the market today. The presence of a new board and the type of board are automatically sensed by the meter’s firmware or by Instrument Setup (IS) software. The QVGA Controller’s kernel software contains a complete set of high level driver routines for the Serial2 port, and these functions are summarized in the Control-C Glossary. The maximum Serial2 communications rate is 4800 baud. You can specify different settings for both ports including baud rate, parity, byte size, stop bits and flow control. COMN, custom and virtual serial ports correctly registered within Windows operating system and visible in device manager under standard "Ports (COM & LPT)" device class.

RS485 is the preferred serial communications standard for long distance industrial communications. The differential voltage system also allows the RS485 to provide longer data transfer distance and lower voltage use, which helps to increase data speed. Ensure power and data lines are connected properly and there are no loose connections. In general it is very important not to run communications wires in the same trough or conduit or in parallel with AC power cables. These cables allow the dual RJ11 jacks of the RS485 option board of Laureate meters (digital interface ordering option 2) to be daisy chained and to be addressed digitally with no need for a hub. What cable should I use to connect meters with an RS485 port to the USB port of a PC? Should I use RJ11 or RJ45 connectors? Why dual RJ11 jacks? RJ11 jacks support half-duplex or full-duplex communications.
