Close all connections then press and hold the CFG RESET switch for three seconds If you release the switch prior to three seconds the GPIB ENET 100 continues to operate normally The PWR RDY LED goes through the following changes during these three seconds 1 The LED begins slowly alternating between red and yellow 2 The alternating pattern increases in tempo 3 At three seconds the PWR RDY LED becomes steady red This indicates the GPIB ENET 100 is ready to enter network configuration mode 4 Now release the CFG RESET switch The PWR RDY LED alternates rapidly between red and yellow to indicate the GPIB ENET 100 is now in network configuration mode This mode remains in effect until you switch off the GPIB ENET 100 or you use the NI Ethernet Device Configuration utility to change its network characteristics The GPIB ENET 100 automatically reboots when you exit the utility National Instruments Corporation 6 3 GPIB ENET 100 for Mac OS Chapter 6 Using Your GPIB ENET 100 and NI 488 2 Using the CFG RESET Switch at Power On If you want to reset the unit to its default network characteristics you can use the CFG RESET switch at power on By pressing and holding the CFG RESET switch while you power on the GPIB ENET 100 the network parameters revert to the default settings as defined on the baseplate label You must press and hold the switch for three seconds If you release the switch prior to three seconds no change
2. When should I use IBIC 488 2 You can use IBIC 488 2 to practice communication with your instrument troubleshoot problems and develop your application program For more information about IBIC 488 2 refer to Chapter 4 Interface Bus Interactive Control Utility in the NI 488 2 User Manual for MacOS How do I use an NI 488 2 language interface For information about using NI 488 2 language interfaces refer to the NI 488 2 User Manual for MacOS My I O worked with a board interface but it times out when I use the GPIB ENET 100 interface What should I do Network communication is slower than straight cable communication You might need to raise the Timeout value using the NI 488 Config utility Refer to Chapter 4 GPIB Configuration for more information How do I communicate with my instrument over the GPIB Refer to the documentation that came from the instrument manufacturer The command sequences you use are totally dependent on the specific instrument The documentation for each instrument should include the GPIB commands you need to communicate with it In most cases NI 488 device level calls are sufficient for communicating with instruments Refer to Chapter 2 Developing Your Application in the NI 488 2 User Manual for MacOS for more information How should I check for errors in my GPIB application Examine the value of ibsta after each NI 488 or NI 488 2 call If a call fails the ERR bit of ibsta is set and an error
3. Try changing the name of the NI 488 INIT to ZNI 488 INIT Because INITs load in alphabetical order the ZNI 488 INIT will load last preventing possible corruption from INITs that load after it If changing the name of the NI 488 INIT does not solve the problem another INIT file might have a conflict with the NI 488 INIT Try removing some of your other INIT files You can store them in a temporary folder in case you need to reload them later You can use the Extensions Manager utility to disable certain extensions and control panels I have a GPIB ENET Can I use the GPIB ENET and GPIB ENET 100 in the same system Yes this version of NI 488 2 supports systems containing both products as well as systems containing only one of the two products How do I configure my existing GPIB ENET with this software This version of NI 488 2 includes options for configuring both the GPIB ENET and the GPIB ENET 100 Use the utilities in the Ethernet folder with the GPIB ENET and the utilities in the Ethernet 100 folder with the GPIB ENET 100 For information on configuring the GPIB ENET hardware refer to Getting Started with Your GPIB ENET and the NI 488 2 Software for MacOS I have an application using the GPIB ENET Can I replace the GPIB ENET with a GPIB ENET 100 Yes You do not need to rewrite your application code to replace a GPIB ENET with a GPIB ENET 100 However you do need to configure the GPIB ENET 100 to have the same network identit
