Setting ID

Rotary switch settings only affect Slot 0 and all other slots are sequentially

increased by a value of one after that slot.

The ID is set sequentially starting from a base address. The base address, or

starting address, is set via a 0-7 position rotary switch located on the personality

module. There is a second 0-15 position rotary switch which can be changed to

modify the base address setting.

The default value for both switches is 0. In this default configuration, the device ID

values are as shown.

The 0-7 switch is used to set the

base address which is multiplied

by 16, and the 0-15 switch is

used to set the offset modifier to

the base address. The formula

for setting the ID is: x(16)+y,

where x is the 0-7 switch and y is

the 0-15 switch.

Ex. The 0-7 switch is set to 2, the 0-15 switch is set to 6. This sets the base address

to 38 (2*16=32, +6=38). So Slot 0 ID = 38, Slot 1 ID = 39, Slot 2 ID = 40, Slot 3

ID = 41, etc… up to Slot 9 ID = 47.

The table below provides the Slot 0 Starting (Base) Address Settings.
