2.1 Connecting the Serial MODBUS Gateway to
the USB Programming Dongle:
BZ-TECH provides MODBUS configuration software that
presents a GUI to the user and makes interfacing to the
MODBUS gateway easy. BZ-TECH also provides a USB to
RS485 dongle to connect the hardware to a PC. To use
the USB to RS485 dongle, connect the wires from the
MODBUS gateway as shown in the illustration below.
Note:
The white wire is not used with the USB
programming dongle. The white should be left
unconnected but protected to prevent accidental shorting.
* Any COM port in a computer may be used with the
software.
Select the version that is compatible with your PC
operating system.
