Appendix 1 Troubleshooting the USB Faults
Check the items in the following table in the event of operating
problems with the USB interface.
(1)The USB does not operate at all.

> -1.Is the cable properly connected?
> >> Refer to the instruction manual.
> (Setting the communication interface)
> -2Please install the USB Driver.
> >> Refer to the instruction manual.
> (Installing Logger Utility)
> (Installing the USB Driver)
> -3.Are all the devices that are connected powered on?

(2)An attempt to read data using the CALL RECEIVE statement causes the USB bus to hang.

> -1.Each and every CALL RECEIVE statement must be
> preceded by a query.
> -2.Is the query transmitted incorrect?
> >>See CHAPTER 1. "1.1 Receive and Send Protocols"

(3)Although a command was transmitted,the unit did not operate.

> -1.Use the "*ESR?" query to check the standard event status
> register for anomalies.
> >>See CHAPTER 1 , "1.2 The Status Byte and the Event Registers."

(4)Even though a number of queries were sent, only one response was received.

> -1.Has an error occurred?
> -2.The response should be read immediately after each query.
> >> To read several responses in one operation, the corresponding
> queries must be combined into a single line using the message
> separator.

(5)Answer that transmitted query has not returned correctly.

> -1.The answer is not received the answer of the first query command
> has had returnas the answer of the query command of after,
> in the case that you sent the next query command
> as after you sent the query command with USB.
> In this case it can do the answer of the untransmission that is remaining
> on the side of LR8410,LR8416 when youI send the *CLS command the clear.
> Please do so that you receive the answer without fail,
> n the case that you sent the query command with USB.

Appendix 2 Troubleshooting the LAN Faults
Check the items in the following table in the event of operating
problems with the LAN interface.
(1)The LAN does not operate at all.

> -1.Is the cable properly connected?
> >> Refer to the instruction manual.
> (Connecting the LAN cable)
> -2Is the setting of LAN correct?
> >> Refer to the instruction manual.
> (IP Address)
> -3.Are all the devices that are connected powered on?

(2)An attempt to read data using the CALL RECEIVE statement causes the LAN bus to hang.

> -1.Each and every CALL RECEIVE statement must be
> preceded by a query.
> -2.Is the query transmitted incorrect?
> >>See CHAPTER 1. "1.1 Receive and Send Protocols"

(3)Although a command was transmitted,the unit did not operate.
