Switching between Remote and Local
Modes
• When Switching from Local to Remote Mode
If the GS610 receives a “:SYSTem:REMote”
command from the PC when it is in the local mode,
it switches to the remote mode.
• The REMOTE indicator to the left of the display
illuminates.
• All keys except the
LOCAL
key are disabled.
• Settings entered in local mode are retained even
when the GS610 switches to remote mode.
• When Switching from Remote to Local Mode
Pressing
LOCAL
in remote mode puts the
instrument in local mode. The GS610 switches to
local mode when it receives a :SYSTem:LOCal
command from the PC.
• The REMOTE indicator to the left of the display
turns OFF.
• Key operations are enabled.
• Settings entered in remote mode are retained
even when the GS610 switches to local mode.
Reception Function
You can specify the same settings as those specified
by front panel key operations.
Receives output requests for measured and computed
data, setup data of the panel, and error codes.
Transmission Function
Outputs measured and computed data.
Outputs panel setup data and the status byte.
Outputs error codes that have occurred.
