IEEE-488 Communication DIP Switch Settings

The 5 DIP switches located on the rear panel of the Model 135/136 are
used to control the IEEE-488 interface. Switches 1 through 5 control the
IEEE-488 bus address of the unit.

4.2.3.1 IEEE-488 primary bus address

The Model 135/136 primary bus address is controlled by switches 1
through 5 of the communication DIP switch on the rear panel. Valid
primary addresses are between 0 and 30. The Model 135/136 does not use
secondary addressing. Note that many IEEE-488 controller cards in
external computers will use address 0. The bus address for each Model
135/136 should be unique with respect to other Model 135/136 units or any
other devices on the bus. The switch settings for the various addresses are
(on = 1 or the up position):
