HP 98644A Asynchronous Serial Interface
b. Set the 626 switch to 1 as shown in Figure 5-31.
6. Set the REMOTE Switch.
a. Find the group of switches labeled SW1 by referring to Figure 5-3l.
Switch 1 in this group is the Remote switch.
b. Set the Remote switch as follows:
• If you are connecting a terminal to this interface and want this
terminal to be the system console, set this switch to 1, which is
opposite that shown in Figure 5-31 .
• If you are connecting a terminal to this interface but do not want this
terminal to be the system console, or if you are connecting any other
device, set this switch to 0 as shown in Figure 5-3l.
7. Insert the Interface.
a. Remove the painted cover plates from the back of your computer until
you find an empty even-numbered slot. (Slots are numbered from the top
down, so the top-most slot is number 1, the next slot down is number 2,
etc.) Do not remove the silver cover plates from the bottom of a Series
300 computer.
b. Insert the Asynchronous Serial Interface, component side up, into the
empty even-numbered slot. Tighten the thumb screws on the metal end
plate until the end plate is flush with the back of the computer.
c. If you changed the select code of the Asynchronous Serial Interface in
step 2, find this number in the set of select code labels supplied with the
interface. Affix this label to the metal end plate.
d. If you have other interface or accessory cards to install, leave the cover
plates off; otherwise, replace them.
8. Record the Select Code.
Make a note that select code 9 (or the alternate select code you chose in
step 2) has been used and is no longer available. Use the "Select Code
Record" form on the Chapter 5, "Interface Cards" tab for this purpose.
