1-3-2. IF-41RS
（
Option
）
- The PW-A power supply unit with a built-in IF-41RS is possible to remote-control when it is
connected with a computer by RS-232C. The computer controlling the PW-A power supply unit is
called the master unit, and the controlled PW-A power supply unit is called the slave unit. It is
possible to connect a maximum of four slave units, which are connected with one another with
modular cables.
- It is also possible to specify equipment other than a computer as the master unit. If the PW-A
power supply unit is specified as the master unit, operating the master unit causes the other four
PW-A power supply units to execute the same operation. (Master operation)
- It is also possible to specify the GP-620 (our GP-IB adapter) or RT-63 (our remote controller) as
the master unit, which may remote-control the PW-A power supply unit.
- The PW-A power supply unit is compatible with the PWR series (our power supply unit). It is
possible to construct a system containing PWR series power supply unit(s).
1-3-3. IF-41GU
（
Option
）
- The IF-41GU is an optional board, which features higher transmission rate than the IF-41RS and
may control more power supply units simultaneously.
- It is connected with a computer through GP-IB or USB. A maximum of fourteen or thirty-two units
may be connected directly with a computer through GP-IB or USB, respectively.
- It is also possible to construct a large-scale system if thirty-one PW-A power supply units are
connected with a PW-A power supply unit directly connected with a computer using two sets of
twisted pair cables and these units are remote-controlled.
1-3-4. IF-41USB
（
Option
）
- The IF-41USB is an option board with the USB connector and local bus, which have the same
functions of those of the IF-41GU.
- It allows the user to construct a system at lower cost than using the IF-41GU.
