A maximum of 125 addresses (1 to 125) can be assigned. Each address may be assigned
only once in the overall bus structure. Addresses 1 and 2 are generally used by the control
systems. Bus addresses
The most significant digit is set with rotary switch H, the least significant digit with rotary
switch L. The switches are labelled in the hexadecimal numbering system (0 to 9, A=10,
B=11, C=12, ... F = 15). A hexadecimal to decimal conversion table is provided in the annex.
