1.6.9 Using the PU connector for computer link
(1) When connecting the control panel or parameter unit using a connection cable
Refer to the Instruction Manual (basic).
(2) For RS-485 communication
The PU connector can be used to perform 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 inverter or read and write to parameters.

(1) Connection of a computer to the inverter (1:1 connection)
zComputer - inverter connection cable
For a connection cable between the computer having RS-232C and the inverter (RS-232C⇔RS-485
converter), refer to the table below.
Examples of commercially available products (as of September, '06)
* The converter cable cannot connect two or more inverters (the computer and inverter are connected on a 1:1
basis). Since the product is packed with the RS-232C cable and RS-485 cable (10BASE-T + RJ-45 connector),
the cable and connector need not be prepared separately. Contact a maker for details of the product.
CAUTION
1. Do not connect the PU connector to the computer's LAN board, FAX modem socket or telephone
modular connector. Otherwise, the product may be damaged due to electrical specification
differences.
2. Pins No. 2 and 8 (P5S) provide power to the control panel or parameter unit.
Do not use these pins for RS-485 communication.
