11-1-8. Local bus connection
The local bus can control multiple PS-A power supply units from a single communication port on a PC.
A PC or sequencer must be connected to the PS-A power supply unit (for which "1" is the system address) that is set
s the master unit. Up to 31 slave units can be connected in a cascade via dedicated modular cables.
The use of RS-485 signals allows the distance between PS-A units to be increased. However, performance may be
delayed because the master unit converts commands.
(1) When IF-70GU is used:
a
ave units are designated by using the ADRS command to specify the system address numb Sl ers.
The IF-70GU interface setting of the slave units can be either USB or GP-IB.
IF-71RS for which RS-232C has been specifie An
Onl
e on. The other terminators are off.
(2) W
d can be used as the interface for slave units.
y the terminators at both ends of the local bus should be on. The rest should be off.

Slave units are designated by using the ADRS command to specify the system address numbers.
Slave units in which IF-70GU boards have been installed can be used.
Only the terminators at both ends of the local bus should be on. The rest should be off.
In the above chart, the terminators for system addresses "1" and "4" are on. The other terminators are off.
11-1-9. When used as a PSR or PSR-M supply unit
When the appropriate settings are specified for the IF-71RS, the PS-A series units are compatible with and can be
used in place of our PSR series and PSR-M series.
For a details about the commands, see the respective PSR series and PSR-M series instruction manuals.
The IF-71RS settings are as follows:
Operation mode CN5 CN6 CN7 CN8 Connector to be used
PSR mode Closed Open Open Closed ※

PSR BUS
PSR-M mode Closed ※

Only the connectors at both ends of local bus should be closed.
The terminators should be on.

Open the connector if a ground loop causes a malfunction to occur.
