14 Configuring the RF Switch

Chapter 1

Setting the Logical

Address

Thelogical addressofthe CascadeRF Switch moduleis set with theLogical

Address (LADDR) switch on the module. The logical address is factory-set

to120.Valid addresses are from 1 to 256.See Figure 1-4 for addressswitch

settings.

The logical address is the sum of the values of the switches set to the

CLOSED position. InFigure 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.

NOTE 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 theResource Manager to determine the logicaladdress assigned to the

module.
