Setting the device address and terminating resistors
Removing the protective cap provides access to two rotary switches for setting the device
address and a DIP switch to set the terminating resistors.
The rotary switches indicate the tens and ones places of the address selected. A setting
of 01 is the delivery state; the PSx3xxDP identifies itself using address 1 at the bus.
To activate the terminating resistors both switches must be in position ON (If active,
remove the connection to a following device).
Switch configurations:
PSx30xDP,
PSx31xDP-8,
Psx32xDP,
PSx31xxDP
PSx31xDP-14,
PSx33xDP-14
PSx34xxDP
Important: Always replace the protective cap after setting the address. This will
prevent dust and contaminants from entering the housing.
