4. Set the Address and System Controller Switches.
SKIP?
Unless you intend to connect two computers together with this
interface, you can skip to step 5. The interface is configured to
be system controller at address 21 and need not be changed.
a. If connecting two computers together via HP-IB, only one of them may
be set to address 21. To change the address of this interface, reset
switches 0 thru 4 in the group of switches labeled U17 (see Figure 5-8).
As an example, to change the address from the default setting of 21 to a
new setting of 20, just change switch 0 in this group to 0 (the opposite of
that shown).
h. If connecting two computers together via HP-IB, only one of them may
be set to system controller. To change this interface to non-system
controller, move the SYS CTL switch shown in Figure 5-8 to the 0
position (the opposite of that shown).
Note: If you will be connecting a disk drive, printer, plotter or other
peripheral to this interface, and you will be using an HP Series 200/300
operating system, do not set this switch to non-system controller.
.1. Insert the Interface.
a. Remove the painted cover plates from the back of your COll1puter until
you find an empty even-numbered slot. (Slots are numbered froll1 the top
down, so the top-most slot is number 1, the next slot down is nUll1ber 2,
etc.) Do not remove the silver cover plates from the bottOlll of a Series
300 computer.
