which should be used for COBRA, VIRGO, Blindows, JAWS and all other Screen Readers,
where a driver for SuperVario2 is available. The line shows then:
prot: baum ht pb1 pb2 hid
"baum" ist marked with dots 7,8.
You can select a protocol by pressing a cursor routing key above ist name. Then this
protocol will be marked with dots 7,8.
Abbreviation "ht" stands for Handy-Tech and "pb" stands for Powerbraille.
The difference between pb1 and pb2 is handling of the keys. Pb2 allows all combinations
of keys which can be assigned in a screenreader whereas this assignement is limited in
pb1.
Hid means Human Interface Device. HID devices are universal input /output devices which
do not need device driver installation. This upcoming protocol is being more and more
accepted by Braille display and screen reader manufacturers and is likely to be a new
standard soon. (COBRA from version 9.1 is supporting HID).
If you select HID as protocol, the communication channel will be set to USB-HID
automatically.
Please only use one of these emulation protocols only if there is no driver for SuperVario2
available. Otherwise use BAUM protocol and the appropriate driver.
Prot: baum ht pb1 pb2 hid
5.2.2

This line selects if SuperVario communicates via USB, wireless Bluetooth or USB-HID
(Human Interface Device) .
Communication Channel: usb bluetooth hid
Comm. Channel: usb bluetooth hid
Selecting HID will make SuperVario2 behave as USB HID device and protocol will be set to
HID automatically. (COBRA from version 9.1 supports HID).
5.2.3
Auto power off
In this line, you can decide whether SuperVario shall automatically switch off after a certain
time of inactivity. Inactivity means no data is transferred and no key is pressed. (APO Time
