2.1.4.1 RJ45, Communication Connect (Except 300LF~750LF)
RJ45 port connection diagram and signal descriptions are summarized below

2.1.4.2 RXP-RXN, Communication Connect
Table 2-13: RXP / RXN Connector Description
The termination resistor of the RS 485 RXP-RXN communication has a purpose of preventing the distortion
and attenuation of the communication line. This resistor means the impedance matching resistor in long
distance transport of RS 485 data. The termination resistor is inserted only in the final stage in single line.
<Terminating resistance selection switch>
- SW7: 055LF/HF~220LF/HF, 300HF~3500HF except 300LF~750LF
- SW1: Only 300LF~750LF
Default Status: Terminating resistance ON
1. Regarding terminating resistance, only applied to RXP-RXN terminals
2. Turn off the switch when master communicate more then one of inverter
(For example : master – PLC, DCS, PC and etc)
RS-485 Terminating resistance On:
RS-485 Terminating resistance Off:
2.1.4.3 ROP 7 CONNECTION (Except 300LF~750LF)
RJ45 connector can also be used to interface with ROP7 option.
Refer to ROP7 option manual.
