3  Communication Modes 
The drive is a slave in the network. It communicates in ‘point to point’ mode. The drive will not response to the 
command sent by the master via broadcast address. 
Users can set the drive’s current address, baud rate and data format by using the drive’ keypad or through the serial 
communication port. 
The drive can report the current fault information when polled by the master. 
EV2000 provides two interfaces: RS232 and RS485. Pay attention that the Jumper CN14 should be in correct position.
