GPIB-4819
GPIB to RS-232 MODBUS
Features:
  • Uses simple GPIB commands to control RTU Modbus devices
    Relieves user from having to format messages and to do CRC checking.
  • Provides GPIB-to-RS-232 and RS-232-to-RS-232 data paths to Modbus device.
    User selects GPIB or RS-232 control of the Modbus device
  • GPIB Interface is IEEE-488.2 Compliant.
    Meets latest GPIB Standards.
  • Saves GPIB address, Serial settings and user's IDN message in Flash.
    Personalizes board as part your end product.
  • Mounts directly to host chassis's rear panel.
    Easy installation eliminates extra cables and reduces cost.
  • Operates on 5 to 12 Volts.
    Runs on any power supply.

    The easy way to configure the interface or use the programs as examples.
Functional Description:
The Model 4819 GPIB<=>Modbus Interface Board has an IEEE 488.2/GPIB to RS-232 Serial Interface for controlling Modbus slave devices from the GPIB or HP-IB bus. The 4819 lets the user send simple read-write messages over the GPIB bus to control and query slave Modbus devices. The 4819 relieves the user from the Modbus packet formatting and error checking tasks. The 4819 also provides all of the required IEEE-488.2 functions and an expanded IEEE-488.2 Status Reporting Structure to report Modbus communication errors. Typical applications are adding a GPIB control to a temperature chamber or to a system that has a Modbus RTU interface.
