 There are 2 communicati
on interfaces in a load cell module which can communicate with a PC or other
devices. COM1 is an RS-232 port, and COM2 is an RS-485 port. Both ports meet the standard MODBUS
protocol. A PC can directly communicate with a load cell module through COM1.
 Delta power supply modules are highly recommended.
