Installation Procedure
Note
Connecting and disconnecting HP-HIL devices while some
language/ operating systems or application programs are
running may lead to unpredictable results. When possible,
connect all needed HP-HIL devices to your computer before
booting a language/operating system or running an application
program.
1. Install the Control Boxes.
a. Select mounting locations for the control boxes. The control box near the
computer must be within 500mm (1.64 feet) of the back of the computer.
b. Remove the paper covering from the back of the fastener pads.
c. Place the fastener pads at the selected locations and press down firmly
for a few seconds.
d. Slide the control boxes onto the fastener pads from the side.
e. Twist the control boxes a few degrees to lock them onto the fastener
pads.
2. Connect the Extension Module.
a. Turn the computer off and check whether there is an existing HP-HIL
cable connected to the "KYBD" (or "KEYBOARD") connector on the
back of the computer. If so, disconnect it.
b. Get the short HP-HIL cable. Find the end of this cable that is marked
with one black dot.
c. Look at the control module nearest the computer. Find the connector on
the back of this control module that is marked with one dot.
d. Plug the "one-dot" end of the short HP-HIL cable into the "one-dot"
connector on the nearest control module.
e. Connect the other, "two-dot" end of the short HP-HIL cable into
the HP-HIL connector on your computer (marked "KYBD" or
