1.1 Remote Interfaces
This instrument is equipped with the following remote interfaces.
GP-IB1 (IEEE 488.2, See Chapter 2)
This port is used to connect a controller such as a PC to remote control this instrument.
Connect a controller or another device controlled by the controller to this port.
This instrument is controlled using remote commands.
Two types of remote commands are provided: the instrument’s native commands
complying with SCPI (Standard Commands for Programmable Instruments), and
commands compatible with the conventional model AQ6317 (see the appendix).
GP-IB2 (IEEE 488.1, See Chapter 5)
The instrument acts as a controller for remote control of external instruments. Connect to
the external device to be controlled using the instrument’s program function.
RS-232 (See Chapter 3)
This port is used to connect a controller such as a PC to control the instrument remotely.
Ethernet (See Chapter 4)
This port is used to connect a controller such as a PC to control the instrument remotely
via network.
GP-IB1 and GP-IB2 Ports
The GP-IB1 and GP-IB2 ports must be used differently for different purposes.
The GP-IB1 port is used when controlling the instrument from a PC.
The GP-IB2 port is used when controlling an external instrument from the AQ6370C/
AQ6373/AQ6375.
Therefore, please note the following.
•A controller such as a PC that is connected to the GP-IB2 port cannot remotely control
the AQ6370C/AQ6373/AQ6375.
• Even if a turnable laser source or an external device to be controlled by the AQ6370C/
AQ6373/AQ6375 using program functions is connected to the GP-IB1 port, it cannot
remote control the AQ6370C/AQ6373/AQ6375.
• The GP-IB1 and GP-IB2 ports are independent of each other. Thus, a controller
connected to the GP-IB1 port cannot directly send a message to an external device
connected to the GP-IB2 port.
• When a PC or other controller is connected to the GP-IB1 port, connecting the GP-IB1
port with the GP-IB2 port results in improper operation.
Do not connect these ports together, or turn OFF the system controller function.
The default is ON.

1.2 Switching between Local and Remote
Switching from Local to Remote
When in Local mode, if a listen address is sent from the controller that sets REN (remote
enable) and ATN to “True,” the instrument enters Remote mode.
• When in Remote mode, the REMOTE indicator lights.
•Keys other than the LOCAL key are disabled.
• Settings entered in Local mode are held even if switching to Remote mode.
• When an LLO (Local Lock Out) message is received from the controller, the
instrument enters local lockout status. In LLO status, the LOCAL key is disabled and
does not return the instrument to Local mode even when pressed. After cancelling the
local lockout status, press the LOCAL key. To cancel the local lockout status, set REN
to “False” from the controller.
Switching from Remote to Local
If you press the LOCAL key when in Remote mode the instrument enters Local mode.
However, it does not return to Local mode if in the local lockout state.
• The REMOTE indicator turns off.
• All keys are enabled.
• Settings entered in Remote mode are held even if switching to Local mode.
• When a GTL (Go to Local) message is received from the controller, the instrument
enters Local mode even if REN is set to False.
