AppendixAppendix Appendix 1 Troubleshooting the RS-232C Faults Check the items in the following table in the event of operating problems with the RS-232C interface. (1)The RS-232C does not operate at all. -1.Is the cable properly connected? >> Refer to the instruction manual. (Setting the communication interface) -2.Is the setting of the communication interfacing RS-232C with the setting screen of the communication? >> Refer to the instruction manual. (Setting the communication interface) -2.Is the unit correctly set? >> Refer to the instruction manual. (Setting the communication interface) -3.Are all the devices that are connected powered on? (2)An attempt to read data using the CALL RECEIVE statement causes the RS-232C bus to hang. -1.Each and every CALL RECEIVE statement must be preceded by a query. -2.Is the query transmitted incorrect? (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)An overrun error or a framing error occurs. -1.Is the transfer rate too high? >> Reduce the transfer rate. Appendix 2 Troubleshooting the 10BASE-T Faults Check the items in the following table in the event of operating problems with the 10BASE-T interface. (1)The 10BASE-T does not operate at all. -1.Is the cable properly connected? >> Refer to the instruction manual. (Setting the communication interface) -2.Is the setting of the communication interfacing 10BASE-T with the setting screen of the communication? >> Refer to the instruction manual. (Setting the communication interface) -2.Is the unit correctly set? >> Refer to the instruction manual. (Setting the communication interface) -3.Are all the devices that are connected powered on? (2)An attempt to read data using the CALL RECEIVE statement causes the 10BASE-T 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.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
