Integrated Sports Systems (ISS) Inc. has a Tricaster LiveText data integration solution for the Omega ARES 21 timing console. The data interface solution is owned by Integrated Sports Systems (ISS) Inc. and is licensed to Water Polo Canada. A symmetrical pin-layout allows two DTEs, data terminal equipment, to be connected directly without use of a modem or other DCE, data communication equipment. The equipment located along a set of RS-485 wires are interchangeably called nodes, stations or devices. The A signals of all devices should be connected with each other and the same goes for the B signals. These signals are commonly called A and B in RS485 systems. Industrial automation systems: In the industrial automation sector, rs485 signal cables play a vital role in connecting and remotely controlling motors. Two wire telephone cables will not function because in that case the ground signal levels on both sides will be floating. Setup is the same when multiple meters are interconnected via cables CBL03, except that all meters now need to be set to a different digital address via their front panel. Laureate meters are modular with a middle slot reserved for a communication board, as illustrated in our Laureates Overview web page.

If the PC is connected to the multiple Laureate instruments on an RS485 bus via an Ethernet-to-RS-485 gateway board or a USB-to-RS485 gateway board, use Laurel’s free XLOG2 datalogging software. RS485 is in its design a different interface from RS232. Bus Probes are a family of low-power environmental sensors with an RS485 interface. The RS485 interface allows the creation of multi-point networks. Is there an easy way to log data to a PC from multiple instruments on an RS485 bus? How fast can I collect data via RS485? What are setup steps for RS485? 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. Both protocols (or communication languages) are built into the instrument’s firmware and are user selectable. Select the firmware for whichever Gen (2 or 3) module you are updating. We found panels produced by JA Solar which are 1689 x 996mm and have a 330W output, and we could fit 5 or 6 of these on the roof between the chimneys.

To get the solar PV power from the roof down to the basement shed, we purchased 20 meters of 6mm armoured cable; this was routed down the back of the house and into the shed through the stone wall. On the Raspberry Pi, we also installed a 1-Wire Pi Plus board, and this is used with a temperature sensor fitted in the shed to monitor the air temperature, which is also posted to the MQTT server and Home Assistant. Boards can be ordered installed with a new meter, and they can also be purchased separately later and be simply plugged in. Can I add an RS485 board to a meter later? If multiple analog input meters or transmitters are digitally addressed in command mode on an RS485 line using the Modbus RTU protocol or the Custom ASCII protocol, the rate becomes about 2 readings per second. The foreword to the standard references The Telecommunications Systems Bulletin TSB-89 which contains application guidelines, including data signaling rate vs. RS485 is simpler because it uses only two wire (or a single pair) to carry out the data in bidirectional manner, using RS232, we need 3 wires at minimum to carry the data bidirectionally.

To prevent noise to interfere with the communications, often twisted pair cable is used. For communications, many of their products are equipped with an RS232 or RS485 serial port. This module is powered by the RS232 port from the connecting computer. The main difference is, that pin 1 and 6 on the RJ11 socket of the MJ20-PRG module are used as power supply. With this boards, a CBL03 lines with RJ11 connectors can branch out to support an RS485 line consisting of three discrete wires. Laureate meter and LT series transmitters support the Modbus RTU protocol and Laurel’s simpler ASCII character based Custom ASCII protocol. 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 RJ11 connector can be used for both RS232 and RS485. Not more than one breakout board is required per RS485 line.
