Page 13: What Your Kit Should Contain
• An electrical loading limit of 15 devices per contiguous bus Each GPIB-130 system extends the distance limit by 300 m and the loading limit to 30 devices (including the extenders), without sacrificing speed or performance. These point-to-point extender systems can be connected in series for longer distances or in star patterns for additional loading. -
Page 14: Optional Equipment
If the equipment is damaged, do not attempt to operate it. Contact National Instruments for instructions. Retain the shipping material for possible inspection by carrier or reshipment of the equipment. -

725.2(B) of the National Electrical Code. To connect an external power supply to the GPIB-130, complete the following steps. Caution: Failure to follow these steps for installation may result in damage to your GPIB-130 and your system. -
Page 17: Connecting To Hewlett-Packard Controllers
Connect the transmission cable to both GPIB-130s. Slide the power switch of both extenders to the on position. The GPIB-130 extension is now operational. Connecting to Hewlett-Packard Controllers To achieve very high data transfer rates and long cable spans between devices, many HP Controllers and computers, such as the 64000 series, use a preload technique on the unit designated Master Controller. -

Buffered mode. However, the GPIB extension is transparent in Unbuffered mode. Buffered Mode In Buffered mode, the GPIB-130 uses FIFOs to buffer data between the remote and local units. For long data streams, you can obtain a much higher data throughput with Buffered mode than with Unbuffered mode. -
Page 19: Setting The Operating Mode
Both GPIB-130s in the extension system must be set to the same operating mode. Use switch position 1 on the side of each GPIB-130 to set the operating mode. Slide the switch to the up position to set Buffered mode; slide the switch down to set Unbuffered mode. See Figure 3-1. -
Page 20: Stored Ppr Mode (Approach 1)
Most other Controllers pulse the IDY signal for about 2 µsec and expect a response within that time. When used with this type of Controller, the GPIB-130 should use the Stored PPR mode if the cable between the extenders is longer than about 60 m. For shorter cable distances, using the Immediate PPR mode is recommended. -
Page 21: Setting The Ppr Mode
Setting the PPR Mode Use switch position 2 on the side of each GPIB-130 to set the PPR mode. Slide the switch to the up position to set Immediate PPR mode; slide the switch down to set Stored PPR mode. See Figure 3-2. -
Page 22: Link Led
The Listen LED is lit whenever a device on the remote GPIB system is identified as a Talker, or if a Controller on the remote GPIB system is actively asserting the ATN message. Whenever the Listen LED of the local GPIB-130 is lit, the Talk LED of the remote GPIB-130 is lit. © National Instruments Corporation... -
Page 23: Chapter 4 Theory Of Operation
Chapter 4 Theory of Operation This chapter describes how the GPIB-130 circuitry operates. This chapter assumes that you have a basic knowledge of the GPIB. If you are a first-time user or you would like to review the basics, refer to Appendix A, Operation of the GPIB, for a history and the basic operation of the GPIB. -
Page 24: System Controller Detection
The GPIB Controllers may be on the local side, the remote side, or both sides of the GPIB-130 extension. Devices on one side of the extension system may pass control or take control from devices on the remote side of the extension. -

Listener. After the message is transmitted, the Controller may unaddress both devices. Some bus configurations do not require a Controller. For example, one device may always be a Talker (called a Talk-only device) and there may be one or more Listen-only devices. © National Instruments Corporation GPIB-130 User Manual... -
