Model 2308 Portable Device Battery/Charger Simulator User’s Manual Section 6: GPIB Operation
Most controllers are equipped with an IEEE-488 style connector, but a few may require a different
type of connecting cable. See the controller’s instruction manual if it is not equipped with an IEEE-
488 style connector.

Daisy chaining
Primary address
Model 2308 ships from the factory with a GPIB address of 16. You can set the address to a value
of 0 to 30. Do not assign the same address to another device or to a controller that is on the same
GPIB bus.
CAUTION
The IEEE-488 connector on the interface accepts metric screws. Do not use
early versions of IEEE-488 cables that do not use metric screws to secure
connections. On the GPIB cable connectors, metric screws are dark colored
while non-metric screws are silver colored.
NOTE
Daisy chaining ( Figure 6-2 ) is recommended when installing multi-unit
connecting schemes.
NOTE
Observe the following limits concerning the IEEE-488 bus:
• There can be a maximum separation of 4 meters between any two
instruments on the bus.
• Make sure the maximum cable length used is the lesser of 20 meters, or
2 meters multiplied by the number of devices.
• Limit the number of instruments on the bus to 15 (maximum) with no two
instruments having the same address.
