Switching from Local to Remote Mode:

If the YOKOGAWA DL6154 receives a “:COMMunicate:REMote ON” command from the PC while in local mode, it switches to remote mode. In this state:

• REMOTE is displayed in the center of the upper section of the screen.

• All keys except the SHIFT + CLEAR key are disabled.

• Settings entered in local mode are retained.

Switching from Remote to Local Mode:

Pressing SHIFT + CLEAR in remote mode puts the instrument in local mode. However, this is not possible if the instrument has received a “:COMMunicate:LOCKout ON” command (local lockout condition). When the YOKOGAWA DL6154 receives a “:COMMunicate:REMote OFF” command from the PC, it switches to local mode regardless of the local lock condition. In this state:

• The REMOTE indication disappears from the screen.

• Key operations are enabled.

• Settings entered in remote mode are retained.

Note: The USB interface cannot be used simultaneously with another interface (Ethernet or GP-IB interface).

When connecting via the USB interface of your YOKOGAWA DL6154, please observe the following precautions:

• Connect the USB cable by inserting the connector firmly into the USB connector.

• When connecting multiple devices using USB hubs, connect the oscilloscope to the USB hub that is closest to the controller.

• Do not insert the USB cable into the GO/NO-GO output terminal. If you do, the instrument may malfunction.

The YOKOGAWA DL6154 responds to specific uni-line and multi-line GP-IB interface messages as follows:

Responses to a Uni-Line Message:

• IFC (Interface Clear): Clears the talker and listener functions. Stops output if data are being output.
• REN (Remote Enable): Switches between the remote and local modes.

Responses to a Multi-Line Message (Address Command):

• GTL (Go To Local): Switches to the local mode.
• SDC (Selected Device Clear): Clears the program message (command) being received and the output queue. *OPC and *OPC? commands in execution are voided. The *WAI and COMMunicate:WAIT commands are immediately terminated.

Responses to a Multi-Line Message (Universal Command):

• LLO (Local Lockout): Disables the CLEAR key on the front panel to prohibit switching to the local mode.
• DCL (Device Clear): Same operation as the SDC message.
• SPE (Serial Poll Enable): Sets the talker function on all devices on the bus to serial polling mode.
• SPD (Serial Poll Disable): Clears the serial polling mode of the talker function on all devices on the bus.

Note: PPC (Parallel Poll Configure), GET(Group Execute Trigger), TCT (Take Control), and PPU (Parallel Poll Unconfigure) are not supported.

Program Messages (Controller to Instrument):

A program message consists of one or more program message units, separated by semicolons (;). The format for a unit is:

<Program header> Space <Program data>

The entire message is terminated by a program message terminator (<PMT>), which can be a New Line (NL), End of Message (^EOM), or both (NL^EOM).

Response Messages (Instrument to Controller):

If a program message contains a query (a command ending in “?”), the instrument returns a response message. A response message consists of one or more response message units, separated by semicolons (;). The format for a unit is:

<Response header> Space <Response data>

The entire message is terminated by a response message terminator (<RMT>), which is NL^EOM.

The following data types are used in communication commands with the YOKOGAWA DL6154:

Multipliers:

Some commands on the YOKOGAWA DL6154 are “overlap” commands, meaning the next command may start before the previous one is complete. This can lead to incorrect query results (e.g., querying a setting before a file load operation has finished applying it). To prevent this and ensure proper synchronization, you can use the following methods:

1. Using the *WAI Command:

The *WAI command holds subsequent commands until the current overlap command is completed. Place *WAI immediately before the command you want to wait for.

2. Using the COMMunicate:OVERlap command:

This command allows you to selectively enable or disable overlap operation for different command types (e.g., media access).

3. Using the *OPC Command:

The *OPC command sets a bit (bit 0, the OPC bit) in the standard event register when the overlap operation is complete. You can then poll this register or wait for a service request to know when it’s safe to proceed.

4. Using the *OPC? Query:

The *OPC? query does not generate a response until the overlap operation is completed. By waiting for the response, you ensure the previous operation has finished before sending the next command.

Synchronization for Non-Communication Events (e.g., waiting for acquisition):

For sequential commands that depend on an instrument state (like a trigger event), you can use these methods:

• STATus:CONDition? Query: Query the condition register to check the instrument’s status (e.g., if it’s acquiring data). You can loop and keep querying until the desired state is reached.

• Extended Event Register: Configure the extended event register and transition filters to generate a service request when a specific condition changes (e.g., when acquisition stops).

• COMMunicate:WAIT Command: This command halts communications until a specific event (based on the extended event register) is generated.

The status byte is an 8-bit register that summarizes the status of your YOKOGAWA DL6154 for remote communication. It is read by a controller via serial polling or the *STB? query to determine if the instrument requires service (e.g., has data to send, or an error has occurred).

The bits of the status byte are as follows:

The Standard Event Register on the YOKOGAWA DL6154 is an 8-bit register that tracks eight different types of standard communication events. When any of its bits are set to 1 (and not masked by the enable register), it causes bit 5 (ESB) of the status byte to be set to 1.

The bits of the Standard Event Register are:

The register can be read and cleared using the *ESR? query. It is also cleared by a *CLS command or by power cycling the instrument.

Output Queue:

The output queue stores response messages to queries. For example, when you send a WAVeform:SEND? command, the requested data is placed in the output queue until the controller reads it. Data is stored and read in a first-in, first-out order. The queue is emptied when:

• The data is read by the controller.

• A new message is received from the controller.

• A deadlock occurs.

• A device clear command (DCL or SDC) is received.

• The instrument is power cycled.

To check if the output queue has data, you can check bit 4 (MAV) of the status byte.

Error Queue:

The error queue stores an error number and message when an error occurs. The contents can be read using the STATus:ERRor? query. Messages are read from the oldest first. If the queue overflows, the last message is replaced by “350, “Queue overflow”.” The queue is cleared when:

• A *CLS command is received.

• The instrument is power cycled.

To check if the error queue has data, you can check bit 2 (EAV) of the status byte.

The YOKOGAWA DL6154 uses specific error codes for issues related to communication commands.
