Setting the Logical Address

NOTE

The logical address of the Cascade RF Switch module is set with the Logical Address (LADDR) switch on the module. The logical address is factory-set to 120. Valid addresses are from 1 to 256. See Figure 1-4 for address switch settings.

The logical address is the sum of the values of the switches set to the CLOSED position. In Figure 1-4, switches 3 through 6 are CLOSED and the associated values of these switches are 8, 16, 32, and 64. Thus, the logical address = 8 + 16 + 32 + 64 = 128.

When using the Cascade RF Switch module with an E1406 Command Module, the address must be a multiple of 8 (for example, 8, 16, 24,...

112, 120, 128,... 240, 248). The module cannot be configured as part of a multiple-module switchbox instrument.

If the Logical Address Switches are set for 255, the System Resource Manager automatically assigns a Logical Address to the module. You can poll the Resource Manager to determine the logical address assigned to the module.

Logical Address

Switch Location

64+32+16+8=120

128 64 32 16 8 4 2 1

1=CLOSED

0=OPEN

Logical Address = 120

CLOSED = Switch Set To 1 (ON)

OPEN = Switch Set To 0 (OFF)
