Remote Operation
5. Remote Operation
5.1 General Information
The AC source can be controlled remotely through the GPIB or the RS-232C port. The GPIB
port is mostly used, but the RS-232C port is helpful too.
Technically speaking, the GPIB interface is quite different from the RS-232C interface. The
GPIB interface is an 8-bit parallel data bus owning a host of bus commands for
synchronization, and up to one Megabyte transfer rate. The RS-232C interface, a series bus
with a few handshake lines for synchronization, is less capable, so its requirement is not so
much, and the user can write a simple program to do basic remote control easily.
5.1.1 Setting the GPIB Address and RS-232C Parameters
The AC source is shipped with the GPIB address which is set at 30. The address can be
only changed from the front panel by pressing the soft key
CONFIG in the “Configure setting”
menu. This menu is also used to select the RS-232C interface, and specify the parameters
of RS-232C such as baud rate and parity.
Set the GPIB address as follows:
1. Press CONFIG to enter into the “Configure
setting” menu. Display of Cursor
2. Move the cursor to the line of GPIB address. GPIB address =30
3. Enter the new address from the numeric keys
such as 5 , ENTER , and the GPIB address
will change to 5. GPIB address =5
Set the RS-232C interface as follows:
1. Press CONFIG to enter into the “Configure
setting” menu.
2. Move the cursor to RS-232C parameters of
baud rate. Baudrate = 4800 Parity=EVEN
3. Select baud rate by pressing
or
key
then press ENTER.
4. Move the cursor to the line of parity, and select parity as you select baud rate.
