You should not need an interface between the HMI and transmitter, since both are RS-485 and support Modbus RTU.

Although testing the HMI's RS-485 port using your computer is a good test, I recommend using a Modbus RTU slave simulator instead of Hyperterminal. This will also allow you to confirm that you've got the HMI's Modbus RTU master settings configured correctly as well as verify the RS-485 communication. There are several Modbus slave simulators available. Here are a couple
