Description

Remote Displays (or Serial Input Meters) are slave displays which accept the RS232, RS485, USB or Ethernet data from computers, programmable controllers, instruments, or other devices with a serial data output. They can also provide relay closures and an analog output based on the received serial data. They blend in with 1/8 DIN digital panel meters, counters and timers to provide a numeric display from -999,999 to +999,999.

Data can be extracted from 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.

meters, counters and timers allow their display to be duplicated by a Remote Display. Remote displays can also be used to display multiple parameters collected by the same counter. While the 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.

A serial communications board is required in the Remote Display. Choices are RS232, RS485 with dual RJ11 connectors for daisy chaining, RS485 with dual RJ45 connectors for daisy chaining, USB, USB-to-RS485 converter, Ethernet, and Ethernet-to-RS485 converter. Three serial protocols are user-selectable: Modbus RTU, Modbus ASCII, and TDM ASCII. The Modbus protocol allows devices by different manufacturers to share the same data line, but the TDM protocol is simpler and is recommended when all devices on the line are s.

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 meter, counter or timer, thereby assuring that the local and remote alarm points are identical.
