8-3-2. Setting addresses
Operation procedures
1. Hold the A key of the PAR-A power supply unit and throw the power switch. Keep holding the A
key until the characters "P-on" displayed on the voltage and current indicators change into "Idno".
When the characters "SyAd" are displayed on the voltage and current indicators, it is possible to
set the system address.
2. Change the value with the rotary encoder and press the MEMORY key. The value is stored.
When the PAR-A power supply unit incorporates the IF-41GU/IF-41USB and the system address
is set to 1, the characters "PcAd" are displayed and operation proceeds to PC address setting.
Likewise, change the value with the rotary encoder and press the MEMORY key. Normal display
is restored after completion of setting.
※
The address setting range differs with the communication method.
◆
See section "9-3-3. Address setting range and set value" below and set the addresses properly.

The connection methods shown in the table above correspond to the descriptions in sections
"8-1.
Connecting IF-41RS " and "8-2. Connecting IF-41GU/IF-41USB ".
※
The number of the addresses is not the same as the number of connectable units.
For the number of connectable unit, see sections "8-2-1. Remote control through GP-IB
(IF-41GU only)" and "8-2-2. Control through USB" .
※
The system address and PC address are set to 1 by default or after the memory is cleared.
<Precautions>
・
Do not assign the same system address to several slave units when the IF-41RS boards are
used.
・
Do not assign the same PC address to several local bus master units when the IF-41GU/ IF-41USB
boards are used. Do not assign the same system address to several slave units connected with
the local bus master unit through the local bus. Otherwise, the units will not run normally.
・
When the units are connected with a computer through the USB, the PC addresses are similar to
the IDs for unit identification. They are different from the USB addresses. The USB addresses
are assigned automatically to the USB devices by the computer and need not be specified.
・
In GP-IB control, a unit having the PC address of 31 runs in the listen-only mode.
