The Super Gemini Embosser and Duxbury DBT

The Nippon Telesoft Super Gemini is a braille embosser that can also print inkprint in a bit-pattern, suitable for many languages.

This document describes a test at Duxbury Systems to support the print and the braille output, with Vietnamese inkprint and braille.

DBT Software Version Information

The Super Gemini is a new embosser model, only supported by Duxbury Systems in recent DBT software.. Here is the link: download the most recent DBT from the Duxbury Website.

The Super Gemini looks like the original Gemini, except that the logo on the left looks as follows:

Unless you have a Super Gemini, you cannot run this test.

Also we are using 9.5 by 11 inch paper, plus the HP C6602A black printer ink recommended for this unit.

Installing the Gemini

We start by first downloading the USB drivers for the Gemini. These are found on this page: Search for the words USBdriver download. Save the zipped file file on your computer. Unzip the file, and make a note of the location of the unzipped directory, called usbdrv.

We are ready to install. Turn on the Gemini, and cable the Gemini to your computer. You should see an icon on the task bar that says "located new hardware". Click on it to start the installation. When it wants to find the installation directory, click on browse, and browse to the usbdrv directory. Everything should go automatically. When I did this on my system, I learned that the unit would operate through COM3 (this is an artificial port name to reference the Gemini through the USB connection).

You may find it necessary to always connect the Gemini through the same USB port each and every time to make sure everything keeps working.

Setting Up the Gemini within DBT

Start DBT dated April 5th 2011 or later (see above). Use the Global Menu, and select Embosser Setup

Setting up an embosser is described in the DBT Help.

You need to select the embosser model of Nippon Telesoft Super Gemini. I set the connection to the Port COM3 because that is the port name reported when I installed the Gemini USB driver software. You may need to select a different name depending on what is presented when you installed the Gemini (see above).

The connection works on 9600 baud, 8 data bits, 1 stop bit, and no parity. These are also the dafaults for DBT.

Note: if you do not see Nippon Telesoft Super Gemini in the list of embossers, you might be running a version of DBT which is too old.

A Word About Interline and Interpoint.

Interline means having an inkprint line between each and every line of braille. Interpoint means having braille (or braille and print) on both sides of your paper. Happily, the Gemini can do both (though interpoint requires a manual operation of re-feeding the paper into the machine for the back side of each page).

On the screen shots shown above, the Interpoint box is greyed out on the second screen. When you use the small spacing (small font), there is not enough space between the lines of braille for the braille to be embossed on the opposite side. This is the reason you cannot produce imterpoint output if you select small spacing.

Please check these settings in the Document, Embosser Set up screen, not in the Global, Embosser Set up Screen. The Global Menu is holds the defaults for newly created documents. The Document Menu contains information on what will happen for this particular document.

If you produce a 10 page document with interpoint, this only uses 5 sheets of paper. When you emboss, you get the "top" pages produced first. Remove these 5 pages, and flip them over and re-feed the paper in to produce the "bottom" pages. You will see a prompt from DBT on the screen. When you are ready, press the Enter key to finish the brailling job. Here are the precise steps:

The Vietnamese Test

To show DBT in action, we chose to produce a sample in the Vietnamese language. Vietnamese has a complex contracted braille system. DBT can back translate from contracted Vietnamese to inkprint. Thus almost all the features shown, use of the Super Gemini and working in Vietnamese, and very new software features.

In DBT (with the embosser selection process closed), I type control-N to select a new Template. I select Vietnamese - Basic. You might have to Select the Region Asia first, then select Vietnamese.

At random, we chose a Vietnamese publication. (Our apologies if this text is not considered politically or socially acceptable.) I clipboarded a paragraph, and pasted this into the inkprint screen of DBT (not a braille screen). Since we already told DBT that this document is Vietnamese, I just type control-T to translate inkprint into contracted Vietnamese braille.

I then select Document, Embosser Setup to make sure that the high-light is on Nippon Telesoft Super Gemini. Also make sure the checkbox for Interline Print is checked. If this box is not checked, you will only get braille output with no inkprint. When I am ready, I close the Embosser Setup screen.

For this test (see the photo), there is no braille on the other side of the paper. If I wanted braille on the other side of the paper, I would also have checked Emboss in Interpoint as well.

I make sure the Gemini is ready to receive data. Here, I recommend that the user be familiar with all of the instructions on the use of the braille device, to avoid any issues.

On DBT, I press control-E, then return, to emboss the current text. I should get inkprint Vietnamese and braille Vietnamese produced on the Gemini.

Sample Taken from Wikipedia (Vietnamese) article about the Battle of Dien Bien Phu


Đến cuối năm 1953, Chiến tranh Đông Dương đã kéo dài 8 năm, Pháp lâm vào thế bị động trên chiến trường, quân đội của chính phủ Hồ Chí Minh đã giải phóng nhiều khu vực rộng lớn ở Tây Nguyên, khu 5, các tỉnh Cao Bắc Lạng,..và nhiều khu vực ở đồng bằng Bắc bộ. Chính phủ Pháp muốn tìm một giải pháp hòa bình có thể chấp nhận được để chấm dứt cuộc chiến nhưng mặt khác họ muốn duy trì quyền lợi tại Đông Dương. Pháp bổ nhiệm tổng chỉ huy Henri Navarre sang Đông Dương tìm kiếm một chiến thắng quân sự quyết định để làm cơ sở cho một cuộc thảo luận hòa bình trên thế mạnh

An Important Note About DBT

When Duxbury DBT translates the inkprint into braille, it does not have access to the inkprint. It only looks at the new braille data. When it needs to make inkprint, it uses its own translation from braille to inkprint to make the inkprint. This might introduce errors in the inkprint. Duxbury Systems always strives to meet customer expectations.
