Wiring and configuration of PU connector
Using the PU connector as a computer network port enables communication operation from a personal computer, etc.
When the PU connector is connected with a personal, FA or other computer by a communication cable, a user program can
run and monitor the converter unit or read and write to parameters.
PU connector pin-outs
NOTE
• Pins No. 2 and 8 provide power to the operation panel. Do not use these pins for RS-485 communication.
• Do not connect the PU connector to the computer's LAN board, FAX modem socket, or telephone modular connector. The
product could be damaged due to differences in electrical specifications.
