Setting the IEEE Address
The IEEE "address" is the method by which the system controller distinguishes one device on the bus from
another. The address of the 4300C is determined by the setting of a binary-weighted switch on the rear
of the instrument. Here are two examples to help you set the address.
Example 1: Switches 1, 2, and 16 are OFF (or 0) and switches 4 and 8 are
ON (or 1).
The resulting address is:
(1 × 0) + (2 × 0) + (4 × 1) + (8 × 1) + (16 × 0) = 4 + 8 = 12
Example 2: Switches 2 and 4 are OFF (or 0) and switches 1, 8, and 16 are
ON (or 1).
The resulting address is:
(1 × 1) + (2 × 0) + (4 × 0) + (8 × 1) + (16 × 1) = 1 + 8 + 16 = 25
The address you choose is entirely dependent on your application and by the type and quantity of devices
on your IEEE bus. Some guidelines to follow are:
Each device on the bus must have its own unique address. Operating two devices at the same address will
produce undefined results and is not recommended.
Avoid setting the 4300C to address 0 (all switches off) or to address 31 (all switches on) as this may
interfere with the system controller.
If the setting of the switches is changed, power must be cycled to place the new address into memory.
Note: In all future examples, we will assume that the address is set to "12".
