Newport LDC-3706 Series User Manual

December 2019 45 LDC-3706 Series Laser Controller
Changing Between Local and Remote Operation
Sending a command over the GPIB or USB bus automatically puts the instrument in Remote mode.
The Remote indicator identifies when the controller is in remote operation mode. When the
instrument is in Remote mode, all front panel controls are disabled except for the Local, Left display,
and Right display buttons. Pressing the Local button returns the instrument to Local control mode.
GPIB vs. USB Communication
The USB interface uses the same command set as the GPIB interface. Command syntax does not
vary between communication protocols.
Command Syntax
This section describes command syntax and structure. This information must be understood in order
to effectively write GPIB control programs. The syntax of GPIB commands follows the rules defined
in the IEEE 488.2 standard.
Letters
Any GPIB command or query must contain all of the letters or all of the upper case letters which are
shown in the command definition. Upper/lower case does not matter; upper case is used in this
manual to identify the required letters. Lower case indicates optional letters. If any of the optional
letters are included, they must all be included, in the correct sequence. Some examples of what
works and what does not are shown below.
