DNSES Installation

Installing the DNSES Controller
You can install the DNSES controller module in any available EISA slot. Before you
install the DNSES controller in your system, you must power down the system
enclosure. See your system maintenance manual for instructions.
Install the DNSES−AA option as shown in Figure 2:
1.

Place the DNSES module in the EISA option slot.

Press the DNSES module until the connectors fully engage with the
motherboard.

Attach the single end of the external sync cable to J1 on the DNSES controller
module (Figure 2).

Attach the adapter cables to the external sync cable.

Connect the communication lines to the adapter cables.

Power up the system enclosure.

Run the EISA Configuration Utility (ECU). The next section contains devicespecific information about the ECU.

DNSES Installation

Figure 2: Installing the DNSES Controller

MA069693

Running ECU
Whenever you add, remove, or move an EISA option, run the ECU to ensure a
conflict-free configuration. The ECU uses a corresponding configuration (CFG) file
for the option to allocate system resources. The ECU also allows you to change
certain parameters for the option. The user-selectable parameters are described later
in this section.
______________________ Note___________________________
In most cases, the CFG file for the DNSES is provided with the ECU
diskette that was shipped with your system. If the file is not found, the
ECU program prompts you to insert the !DEC2F00.CFG diskette
(AK−Q766A−CA) that was shipped with the DNSES controller.

Run the ECU as follows:
1. Start the ECU according to the instructions provided with your system
documentation.
2.

Following the ECU copyright screen, the ECU loads the configuration file for
the DNSES.
If the file is not found on the ECU diskette:
•

The ECU program prompts you to insert the DNSES configuration
diskette (!DEC2F00.CFG) in the floppy drive.

DNSES Installation

•

The system copies the DNSES configuration file to main memory.

•

The system prompts you to insert the system ECU diskette.

•

The DNSES configuration file is copied from main memory to the system
ECU diskette.

•

After the configuration files are read (this may take a few minutes), an
information screen appears, prompting you to press Enter to load the
configuration files.

While the configuration files are loading, the ECU displays the following:
Loading configuration files
Please wait...
When the files have finished loading, a menu similar to the following is
displayed:
EISA Configuration Utility
Steps in configuring your computer
STEP 1: Important EISA configuration information
STEP 2: Add or remove boards
STEP 3: View or edit details
STEP 4: Examine required details
STEP 5: Save and exit
>Select=ENTER<

<Cancel=ESC>

DNSES Installation

Select the View or edit details option and press the Enter key.
Use the up and down arrows to scroll through the list until you find the DNSES
controller and its slot number. A display similar to the following example lists
the option's current parameter settings:

Slot 5 - Digital WANcontroller/EISA (DNSES)

DNSES Interrupt Mode.............Edge TRIGGERED INTERRUPT
DNSES Interrupt Request Level....IRQ 10
Enable/Disable DNSES Interrupts..Enable DNSES Interrupts
DNSES MEMORY ADDRESS SPACE.......000080000H00008FFFFH
(64KB)
To change any of the settings (edit details), use the up and down arrows to
select the parameter you want to change, and press Return. The following table
lists the user-changeable parameters and their settings.
______________________ Note___________________________
If you select configuration information that conflicts with another device,
for instance a duplicate IRQ level, the utility informs you that in order to
accommodate your selection, certain parameters will need to be changed.
If you press Enter when prompted, the utility will automatically make the
required changes.

When you have finished with the option settings, press F10 to return to the
previous menu.

DNSES Installation

Select Save and exit and press Enter. You will be prompted to verify that you
want to save the configuration before a screen similar to the following is
displayed:
Reboot

Your configuration file has been saved, and if possible a
backup SYSTEM.SCI file has been made on the current drive.
To complete your configuration, you must do one of the
following:
If you need to install boards or change switches and jumpers
on boards already installed, turn off your computer and do
so.
If you want to test your system or install an operating
system, press ENTER to restart your computer, run the
configuration utility again and select the appropriate main
menu item.
If you are finished configuring, remove the SYSTEM
CONFIGURATION diskette if it is in drive A and press ENTER to
restart your system.
>Ok=ENTER<

Follow the directions on the screen display until you have saved and exited the
ECU.
5.

Refer to your system documentation for instructions on returning to the
operating system console.

______________________ Note___________________________
The total length of cable (adapter cable and extension) must not exceed
27 feet (8.23 m).

Supported Cables
Appendix B contains a list of adapter cables supported by the DNSES controller.
These cables connect to the external sync cable and not to the module itself.

Module Isolation
Except at the connector, which plugs into the host expansion slot, clearance and
creepage distances (Xmm and Ymm in Table A-2) must be maintained between the
DNSES module and other parts of the host, including any expansion cards fitted.
Clearance is the shortest distance in space between two points. Creepage is the
shortest distance along a continuous surface between those same two points.

If in doubt, seek advice from a telecommunications safety engineer. Failure to install
the DNSES module in accordance with these instructions will invalidate the British
Approvals Board for Telecommunications (BABT) approval.

Apparatus Between the Approved Host System and Digital Circuit
(PTT)
If any other apparatus, including cable or wiring, is to be connected between the
approved module and the point connection to any particular digital circuit, then all
the other apparatuses shall conform as follows.

1 The creepage distance applies when the installation is in a typical office environment. The creepage
distance shown in parentheses applies when the host computer is subjected to conductive pollution or
dry nonconductive pollution, which could become conductive due to condensation.
2 Voltage used or generated by other parts of the host or expansion card.

A-2

United Kingdom Specifications

The overall transmission characteristics of all other apparatuses shall introduce
no material effect upon the electrical conditions presented to one another by an
apparatus and a digital circuit.

All the other apparatuses shall comprise only:
•

Apparatuses approved (such apparatuses may be subject to limitations on
their use) for the purpose of connection between the apparatus and a
particular digital circuit.

•

Cable or wiring that complies with code of practice for installation of
apparatuses covered by this standard or other applicable requirements.

Host Power Rating
You must ensure that the total power drawn by the approved module, the host, and
other auxiliary equipment drawing power from the host is within the rating of the
host power supply.
Digital has designed all permutations of the host configuration to operate within the
limits of the host power rating. The module power ratings are:
+5 V at +4.0 A
+12 V at +0.5 A
The permissible power supply variation to the module is:
+5 V ±5%
+12 V ±5%

Cable Approval
The module is approved for direct connection to a particular digital circuit. This
approval includes an interconnecting cable with mating connectors that conform to
the British Standard BS6623 parts 1 and 4. If the module is connected to the service
with anything other than its own approved cables, those cables must benefit from the
relevant General Approval NS/G/1235/100009 and/or conform to any other
applicable requirements.
