4 Install the Console Terminal
The next step in installing your MicroVAX 3800 or VAXserver 3800 system
is to set up the console terminal. You use the console terminal to
communicate with your system. Your console terminal is packed with the
following:
•

Video monitor

•

Keyboard and keyboard cable

•

Console terminal power cable

•

Documentation, including an installation guide and user's manual

Unpack the terminal and documentation. Use the instructions in the
terminal installation guide to connect the various components of your
terminal.
Read the instructions on installing and using your terminal that were
provided with your console terminal. Before you connect the console
terminal to your system, turn on the terminal to make sure it works
correctly and perform some set-up operations.
The terminal performs a self-test every time you turn it on. The
documentation for your terminal describes a successful self-test and
possible error messages that display if the terminal is not operating
properly. Once the terminal passes the self-test, you should perform some
set-up operations.

4.1 Perform Set-Up Operations
Set-up involves choosing how your video terminal operates. Certain
parameters must be selected so that your terminal can communicate with
your system: the terminal's baud rate should be set to 9600, and receive
speed should be set to equal the transmit speed.
You choose set-up options from a series of menus that display when you
press the ISet·Upl key on the terminal keyboard. Set-up instructions for
terminals vary according to model, or, in some cases, according to which
read-only memory (ROM) cartridge is installed in your terminal. Be sure
to read the documentation provided with your terminal.
While most default settings are acceptable, you should perform the set-up
procedure for your terminal to ensure appropriate set-up values. The two
examples that follow provide set-up instructions for VT300- and VT200series terminals.

6.1 Connect Terminals and Serial Printers
You can connect up to 16 terminals and/or serial printers for each CXA16
or CXB16 module installed in your system. If the site has been prepared
properly, the lines for the additional terminals and printer(s) are clearly
labeled, and terminate near the system.
You do not connect the terminals and printers directly to the system, but
to a cable concentrator (H3104), which has connections for up to eight
terminals and printers. You then connect the cable concentrator to the
system with a BC16D cable. The cable carton contains two H3104 cable
concentrators and two BC16D cables for each CXA16 module in your
system.
Connect the additional terminals and printers as follows:
1. Find the H3104 cable concentrator and BC16D cable in the cable carton.
2. Feed one end of the BC16D cable under the system box from the back.
or side and plug it into the connector. If you are going to connect both
BC16D cables, connect the first to the connector labeled 8-15 on the
CXA16 cover panel. If you are going to use only one BC16D cable,
connect the cable to the connector labeled 0-7. Lock the connector into
place by using the bail latches shown in Figure 6.
3. Plug the other end of the BC16D cable into the cable concentrator. Lock
the connector into place by using the bail latches.
