Delab DM-50 Modbus

Thanks for your kind information.
I’m waiting for some products to make a sample SCADA system.
Meanwhile I have basis knowledge about Ignition SCADA and also Modbus.
This sample project I’m trying to use DELAB multi function meter DM-50, it supports Modbus communication.
My question is, is there anyone who familiar with this meter DM-50 or other multifunction meter?
I think I need RS485-USB converter or RS485-Ethernet converter to connect this meter directly to SCADA system, right?
