2.1 Connecting the Serial MODBUS Gateway to

the USB Programming Dongle:

Monnit provides MODBUS configuration software that

presents a GUI to the user and makes interfacing to the

MODBUS gateway easy. Monnit 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.

The USB driver for this device can be downloaded at:

operating system.
