RS-232 Capabilities of the AC Source
The ac source provides an RS-232 programming interface, which is activated by
commands located under the front panel Address key. All SCPI commands are
available through RS-232 programming.
The EIA RS-232 Standard defines the interconnections between Data Terminal
Equipment (DTE) and Data Communications Equipment (DCE). The ac source is
designed to be a DTE. It can be connected to another DTE such as a PC COM port
through a null modem cable.
RS-232 data format
The RS-232 data is an 11-bit word with one start bit and two stop bits. The
number of start and stop bits is not programmable. The following parity options
are selectable using the front panel Address key:
Parity options are stored in non-volatile memory.
Baud rate
The front panel Address key lets you select one of the following baud rates, which
is stored in non-volatile memory:1200, 2400, 4800, or 9600.
NOTE
The RS-232 settings in your program must match the settings specified in the
front panel Address menu. Press the front panel Address key if you need to
change the settings.
EVEN Seven data bits with even parity
ODD Seven data bits with odd parity
NONE Eight data bits without parity
NOTE
The ac source must have the same baud rate and parity as the controller.
