HP-MSIB/HP-IB Addressing An element in an HP 70000 Modular Measurement System is a system component able to communicate with other modules over HP-MSIB. Element addresses must adhere to the set of rules de ned in this section (HP-MSIB addressing di ers from HP-IB addressing). For system addressing information, refer to the local oscillator installation and veri cation manual.
Address Matrix The address matrix, as Figure 2-4 shows, is a graphic representation of addresses on the HP-MSIB. The 8-row by 32-column matrix implies 256 available addresses; however, there are actually 255 legal addresses plus an illegal address at row 0, column 31. Figure 2-4. The Address Matrix Each element must have a unique 8-bit binary HP-MSIB address correctly placed on the address matrix.
The master determines its slave-area boundaries by rst searching upward in its own column starting in the master's row, then in each higher column starting in the master's row. The search stops at the boundary column or, if there is no de ning element, after searching column 31. The master uses the following criteria to set slave area boundaries. 1. The left boundary-column equals the master's column address. 2.
3. Set the column switch sections to the binary value of the module's HP-MSIB column number. For example, if the column value is 19, set the switches to binary 10011, as Figure 2-6 shows. Note 2-10 Changing HP-MSIB addresses requires an understanding of HP-MSIB addressing rules. For help with custom con guration addressing, refer to the system-master installation and veri cation manual.
