Communications Methods

Communications Unit Number

To communicate with the host computer, set a unit number for each Inverter so that the Inverters can
be recognized by the host computer. The unit number can be set to an integer value between 0 and
99.

Note When communicating with multiple Inverters, do not set the same unit number for more than

one Inverter. If the same unit number is set for more than one node, the system will not operate
correctly.

• Up to 32 nodes including the host computer can be connected in a 1:N system.

• When connecting a 1:N system, make sure that the communications specifications are the same for

all the node that are connected. In addition, set a unique communications unit number for each
node.

Communications Baud Rate

This parameter sets the baud rate for communications with the host computer. The communications
baud rate settings are as follows: 
2.4 (2,400 bps), 4.8 (4,800 bps), 9.6 (9,600 bps), and 19.2 (19,200 bps).

Communications Data Length

This parameter sets the number of communications data bits. Set either “7 bits” or “8 bits.”

Communications Stop Bits

This parameter sets the number of communications stop bits. Set either “1 bit” or “2 bits.”

Communications Parity

This parameter sets the communications parity. Set the parity to “none,” “even,” or “odd.”
