Front panel control and setup
The modem is equipped with a display (2 x 24 characters) and 5
switches (ROLL/EXEC, CURS, VOICE/DATA, MAN/AUTO, and
LEA/SW). This will give a high degree of flexibility when it comes to
modem setup.
e Most of the modem parameters may be changed from the menu.
Normally it will not be necessary to setup the modem from an
asynchronous terminal, save these parameters, and then move the
modem back to the place where it shall operate.
e The display will give important real time information such as
Handshake, Dialing,Line quality, Bit errors etc.
For setup and control of the modem you may choose the "full access
display" or the "simplified access display". Which alternative to use is
controlled by jumper field J5 position 4. The simplified version is
chosen if you put a jumper at that position.
e The full access version will be the default choice and will give
access to all setup-entries and tests.
e The simplified version will give access to Loop3 in command mode
and to the Transmit+ Receive test in Data mode. No access to the
setup will be possible.
When turning the power on the display will give the information
expressed byt the window below.
