Laureate - Serial Input 6-Digit Panel Meter & Remote Display

Serial streaming data can be received in the form of RS232, RS485 or USB at rates up to 9600 baud. Streaming data can be provided by Laureate meters, counters or transmitters programmed for the Custom ASCII protocol in continuous mode, or by other instruments, like weighing scales from different manufacturers. Readings can be extracted from streaming ASCII strings that contain multiple data values and non-numeric characters, such as Start and Stop characters. Any number of characters between the Start character and the data can be masked Off. Up to 8 display characters (including sign and decimal point) can be masked On. Any number of characters between the last displayed character and the Stop character can be masked Off.

Laureate meters, counters and timers allow their display to be duplicated in streaming mode by a Laureate Remote Display, which can be used to display multiple parameters collected by the same counter. While a Laureate counter can only display one selected parameter at a time (such as rate A), it can transmit multiple parameters (such as rate A, rate B, ratio A/B and peak). The Remote Display can be set up to display any serially transmitted item, and an indicator light shows which item has been chosen for display.

Commands using the Modbus or Custom ASCII protocol can be used to download specific readings into the Remote Display using RS232, RS485, USB or Ethernet TCP/IP communications. These readings can be displayed, be converted into a scaled analog output, and/or be used to control relays, depending on configuration of the remote display

An optional isolated analog output board allows the Remote Display to serve as a highly accurate 16-bit digital-to-analog converter and transmitter.

An optional relay output board with 2 or 4 relays can add remote alarm or control capability. The relays can be 8A contact relays or opto-isolated 120 mA AC/DC solid state relays. The relays can respond to the transmitted values or to any of 8 serially transmitted control characters. The control characters can be generated by a Laureate meter, counter or timer, thereby assuring that the local and remote alarm points are identical.
