(4) When local bus is used:
Use a straight 6-pin modular cable for the local bus connection.
This cable is a twisted pair cable with D+ and D- signals. Four different lengths are available.
11-1-5. Address settings
If the IF-70GU, IF-71LU, or IF-71RS is mounted on the PDS-A power supply unit, the address setting will appear on
the menu when the unit is turned on and started by pressing and holding the MENU key.
There are two types of addresses for PDS-A units: a system address (SYAD) and a PC address (PCAD).
● The system address is used to identify the PDS-A power supply unit when the unit is connected via a local bus.
This address is specified by the IF-70GU, IF-71LU or IF-71RS. The system address must be specified as
Address 1 of the unit which is connected to the controller (PC or sequencer).
Communication with the controller is only possible if the system address has been specified as Address 1.
If you assign multiple system addresses to a local bus, make sure to assign a different value for each address. If
you assign the same value multiple times, communication errors might occur.
● The PC address is used to identify the PDS-A unit when the unit is directly connected to the PC.
The respective use of the PC address varies according to the connection method.
* When a USB is used, the PC address acts as a device address. In this case, do not connect PDS-A power
supply units that have the same address.
