On the TS-7670 with a standard UART communications device, the '-m 7670' switch should be specified.  This allows the proper hardware setting for the RS-485 port to be utilized.

On SBC products with a host USB port for communications, the -c switch should be specified and paramater should be the USB to Serial communication device, which is generally '/dev/ttyACM0'. The '-s f6' switch and parameter is required since the unit operates at a different slave address when operating via USB. The bit rate does not need to be specified, since the USB port will operate at the fastest rate possible (up to approximately 1000000 bps).

These programs are used to perform accesses to the Modbus devices register set. It allows the writing of arbitrary hex data to any hex register address one at a time and the reading of blocks of arbitrary data from any hex register addres displayed in hex, signed, or unsigned decimal.

  • Use of this utility requires the following steps:
    • 1. Select the COM port from the drop down box
    • 2. Select the bit rate from the drop down box
    • 3. Select the correct data format (8N1 is default)
    • 4. Enter the connected device slave address after selecting the format (Hex or Decimal)
    • NOTICE:The coil functionality is currently not functional in Windows
    • 5. Select the resource type (Regoster, Input, or Coil)
    • 6a. Set the resoucw index (e.g., Register number) and count for reading
