HP-IB Address
Each device on the HP-IB (IEEE-488) interface must have a unique address.
You can set the power supply’s address to any val ue between 0 and 30. The
current address is displayed momentarily on t he f ront panel when you turn on
the power supply . The address is set to “05” when the power supply is shipped
from the factory.
The HP-IB address can be set from the front-panel only.
• The address is stored in non- volati le mem ory, and does not change when
power has been off or after a remote interface reset.
• Your HP-IB bus con troller has its own address. Be sure to avoid the bus
controller’s address for any instrument on the interface bus. Hewlett-
Packard controllers generally use address “21”.
Baud Rate Selection (RS-232)
You can select one of six baud rates for RS-232 operation. The rate is set to
9600 baud when the power supply i s shipped from the factory.
The baud rate can be set from the front-panel only.
• Select one of the following: 300, 600, 1200, 2400, 4800, 9600 baud. The factory
setting is
9600
baud.
• The baud rate selection is stored in
non-volatile
memory, an d does not
change when power has been off or after a remote interface reset.
Parity Selection (RS-232)
Y ou ca n select the parity for RS-232 operation. The power supply is conf igured
for no parity and 8 data bits when shipped from the factory.
The parity can be set from the front-panel only.
• Select one of the following:
None
(8 da ta bi ts,
factory setting
), Even (
7
data
bits), or Odd (7 data bit s). When you set t he parit y, you are indire ctly setting
the number of data bits.
• The parity selection is stored in
non-volatile
memory, and does not change
when power has been off or after a remote interface reset.
