At Release 4.1 and later, the MS/TP address of the ZFR1825 Coordinator is no longer fixed at 2. The new address is 120 plus the sum of the first three values of the PAN Offset that are set to the ON position, giving an MS/TP address range of 120 to 127.

Figure 1. Setting the DIP Switches

Note: Only PAN offset switch positions 1, 2, and 4 set to the ON position count towards the MS/TP address of the ZFR1825 Coordinator. See the top of Figure 1.

The PAN Offset of the ZFR1825 Coordinator is configured by adding the values associated with the first seven switch positions (right to left). The eighth switch position is not used and should be set to OFF.

Figure 1 shows the following example case:

  • The PAN Offset is configured to 13 by setting values 1, 4, and 8 to the ON position.

  • The MS/TP address of the ZFR1825 Coordinator is configured by adding the values associated with the first three switch positions (right to left). The sum of the values is 5, so the MS/TP address of the ZFR1825 Coordinator is 120 + 5, which equals 125.

Up to 8 ZFR1825s can be connected to the same FC Bus. When using multiple ZFR1825s, choose sequential PAN Offset values to avoid MS/TP Address conflicts.
