6 MENU SYSTEM
6.1 INTRODUCTION
All configuration & monitoring features are accessed from the front panel via the menu system. Provided
an operator has an understanding of
how
the menu system works, there is no need to try and memorise
the menu structure itself, as selecting a single option (
ÍÛÌËÐô ×Ò×Ì×ßÔóÝÑÒÚ×Ù
, explained later) will
make the unit prompt for all needed configuration parameters. The structure of the menu system is
however shown on the next few pages for reference.
THE 1 MINUTE GUIDE TO FRONT PANEL OPERATION
The main menu can be accessed from any display with the
Óß×Ò
key. It is from this main menu that all
functions are selected.
1:Status 2:Change 3:Monitor 4:Info
5:Log 6:Test 7:Setup 8:Action 9:Help
Main Menu
Whenever the ' ' or ` ' symbol appears it indicates that further information is available by pressing the
ËÐ
or
ÜÑÉÒ
key. This information is usually worth looking at (otherwise we wouldn
'
t have put it there !).
The
ÒÑ
key functions as a backstep/backspace key, both when entering numeric data, and when
traversing the menus. The
ÇÛÍ
key doubles as an enter key for numeric entries. Where a numeric entry
requires many digits (eg IF frequency), pressing
ÇÛÍ
after entering all
significant
digits fills the rest of the
entry with zeroes, pressing
ÇÛÍ
again, enters this value.
When the user is requested to select a configuration parameter, the last setting is always displayed in
[square brackets]. To select the same option again, just press the
ÇÛÍ
Key (ie you don t have to reselect
the same option to get past the menu, just press
ÇÛÍ
)
Options displayed with a colon eg "
1:Status
" switch to another screen or subsequent menu but do not
affect operation. Options displayed with a equals sign eg "
1=Off
" change the configuration and may (if
changing a relevant parameter) affect the traffic. Reselecting a current option (or pressing YES to select
the current option) will never cause a traffic interruption.
When a unit is shipped (or if the non-volatile memory is cleared) it will have an blank configuration and
require the operator to use
ÍÛÌËÐô ×Ò×Ì×ßÔóÝÑÒÚ×Ù
prior to allowing
ÍÌßÌËÍ
to be selected. This
prompts for all parameters required for a complete configuration.
Wherever possible menus state (normal) after the most common option. If in doubt, select the normal
option if there is one, it works every time !
After
ÍÛÌËÐ
,
×Ò×Ì×ßÔ ÝÑÒÚ×Ù
has been performed once, minor changes to the configuration may be
made with the
ÝØßÒÙÛ
option from the main menu.
ÝØßÒÙÛ
allows parameters such as Tx & Rx
service/data rates, clocking, IF frequencies, and miscellaneous parameters to be set without going
through the entire
ÍÛÌËÐ
process. If however you make a major change to the service (such as switching
from Closed Net to IBS) you might decide a quick run through
ÍÛÌËÐ
,
×Ò×Ì×ßÔ ÝÑÒÚ×Ù
again (accepting
the current values with the
ÇÛÍ
key) will highlight any new parameters (with sensible defaults) that are
relevant to this major change of service.
Make use of the Rx=Tx option, it s great, it cuts down configuration errors, and generally makes life
easy. At least read the note on Rx=Tx in section 6.7 on page 89 so you know what you are missing !
