1 Installing and Configuring the 82350
After the 82350 is installed in your PC, the next step is to connect your GPIB instruments to the installed 82350. Suggested steps follow. When you have made the connections, go to “Step 4 - Configuring the 82350”.
1Review Connection Guidelines. The recommended method for connecting a GPIB system is a linear arrangement with the system controller (PC) at one end of the system. However, a GPIB system can also be connected together in a star, linear, or a combination configuration as long as the total number of devices on the system is £ 14 and these guidelines are followed:
•To minimize stress on connector mountings, no more than three cable connectors blocks should be stacked on top of one another.
The GPIB connector screws should be finger- tightened only.
•Minimize cable length as much as possible. All system devices must have tri- state drivers and must be powered on. Systems with devices not using tri- state drivers are limited to transfer rates < 250 Kbytes/sec.
•For operation with data transfer rates < 500
Kbytes/sec, the total length of all GPIB cables is ≤2 meters times the number of
devices connected together, up to a maximum of 20 meters.
•For operation with data transfer rates > 500 Kbytes/sec, the total length of all GPIB cables is > 1 meter times the number of devices connected together, up to a maximum of 15 meters.
•The length between adjacent devices is not critical as long as the overall restriction is met. GPIB bus extenders are available that allow operation over much greater distances.
