1.As a stand-alone unit (the only unit at the address). It has a primary address in the range of 0 to 30. For example: 5 or 7.

2.As the direct unit in a serial link. It is the only unit connected directly to the GPIB bus. The primary address is unique and can be from 0 to 30. It is entered as an integer followed by a decimal separator. The secondary address always is 0, which may be added after the primary address. If the secondary address is omitted, it is assumed to be 0. For example: 5.0 or 7.

3.As a linked unit in serial link. It gets its primary address from the direct unit. It has a unique secondary address that can be from l to 15. It is entered as an integer preceded by a decimal separator. For example: .l or .12

When you enter a secondary address, leading zeros between the decimal separator and the first digit are ignored. For example, .1, .01, and .001 are accepted as secondary address 1 and displayed as 0.01. Zeros following a digit are not ignored. Thus, .10 and .010 are both accepted as secondary address 10 and displayed as 0. 10.
