Chapter 4
Connecting External Devices to
VME Option Boards
This chapter describes how to connect peripheral devices to VME boards installed in
your computer unit’s VME card cage. It also describes the cables and connectors you
need, and how to set up and connect VDA/128 and VDA/255 communications
clusters.
WARNING: All of the instructions in this chapter begin with the
assumption that your computer is turned OFF, and that you
have disconnected the power cord(s) from your computer
system’s power source(s). Refer to your installing and/or
expanding manuals to review safety precautions, if necessary.
You should review the configuration guidelines in your setting up manual(s), and
read the sections on each optional device your system will include, before you begin
setting up the remainder of your system. Set up your peripherals according to the
device-specific manuals for each device, and then follow the procedures in this
chapter to connect them to your system.
NOTE: After you connect devices to your VME option board(s), you must power up
your computer system, and then modify your system software to recognize
and enable the new devices. If your system will run DG/UX Release 4.30
or one of its updates, refer to Installing and Setting Up the DG/UX

System on Stand-Alone Multiuser AViiON

Computers for instructions. If
your system will run DG/UX Release 5.4.0 or higher, see Customizing the
DG/UX

System.
We recommend that you run an AViiON System Diagnostics acceptance
test the first time you power up, and after adding any new devices to your
system. Refer to Using AViiON
