Installation
Millimeter-Wave Controller
GPIB Address Switch The millimeter-wave controller has an GPIB address switch located in the
lower right area of the rear panel. The address of the controller is normally
set to 23 (binary 10111).
The address switch is illustrated below; the individual bits are set by rocker
switches (in the illustration, the darkened side of each switch is the side that
is pressed in). Note that the switch has the MSB on the right, not the left, so
the selected address (binary 10111) reads, left to right, as “11101”.

Fuse The fuse is located inside the line module on the rear panel of the
millimeter-wave controller, as shown in the illustration below. For 110 V
operation, the fuse rating should be 6 A; for 220 V operation, it should be
3 A (or 3.15 A). Review the information on the right of the drawing to
replace the line fuse or to set the voltage selector cam.
WARNING Forcontinuedprotectionagainstfire hazard,replace the linefuse onlywith the
