That will be an INKA.

On the disks supplied with the display should be documentation for the
original DOS drivers. You may need to upgrade the firmware in order to use it
with BRLTTY, however. To do this, you should contact BAUM and give them the
serial number of the INKA, which is printed on the under side of the device.

What is the version number displayed on the INKA when you connect it to a
computer and start it up? Note that the version number is represented using
dot-6 numbers. If it says "mode 1" at the end of the version number then you
have the necessary firmware; otherwise you'll probably need an upgrade.

For use with BRLTTY you should connect both the keyboard port and the serial
port. INKA is capable of working entirely from the keyboard port, but the
Linux kernel keyboard driver can't handle this, so for now at least you'll
need to connect both the keyboard and serial cables.
