Note: For the 4 to 20mA range, the offset, 4mA, must first be subtracted from the physical input value
before dividing by the scale factor to yield the expected %AQG value for the given input.

SETTING ID SWITCHES
CsCAN Network IDs are set using the hexadecimal number system from 01 to FD. The decimal
equivalent is 1-253. Refer to following Conversion Table, which shows the decimal equivalent of
hexadecimal numbers. Set a unique Network ID by inserting a small Phillips screwdriver into the two
identical switches.
Note: The CsCAN Baud Rate for SmartStix I/O is fixed at 125KBaud
