ENIGMA XM88422 Digital Receiver
Version 1.50
29
There are two options that can be used to minimize
the possibility that a faulty control panel will hold up
the receiver for too long.
It is possible to limit the number of events the
ENIGMA will receive from a control panel in one
communication. This option can be enabled at the
Format Options, Limit Calls section:
Max.Events/Call
000 x 16 (00=UL)
The number of events per call can be set by 16, from
0 to 240. 0 means, that the number of events per call
is not limited. This is the default setting.
The other option is the time limiting for hold up. The
time given here defines the time the receiver will stay
online without receiving a valid event. This can be set
at the Format Options, Holdup Time section of the
menu:
HoldUp Time
255 x 100 ms
The value can be decreased with < and increased
with >. The default setting is 255 which means that
the receiver will terminate the call if no valid event is
received within 25 seconds to the last kissoff.
The format selection options define how the Line
Card should decode some of the incoming messages
from the digital communicators. Normally, the Line
Card can recognize the format of the communication
events automatically, but in some cases it requires
further information to choose between possible
formats.
One of these is the 4/1
– 3/2 – 3/1+parity distinction.
It tells the Line Card, that how it should decode the
message if 5 digits were received. Choosing between
4 and 3 digit account codes can be done at the
Format Options, 4/1-3/2 Select section of the menu:
3/x-4/1 Format
(3/x)
To select 4/1 format (4 digit account codes), press
the > button, to select to 3/2 or 3/1+parity format (3
digit account codes) press the < button. The default
setting is 3/x.
If 3 digit account codes are selected, the distinction
between the 3/2 and the 3/1+parity formats can be
made at the Format Options, 3/2-3/1/P Sel. Section:
3/1/P-3/2 Format
(3/1/P)
Pressing the < button, the 3/1/P format is selected,
by pressing the > button, the 3/2 format is selected.
The default setting is 3/1/P. If 4 digit account codes
are selected, this setting has no effect.
The Line Cards can also receive extended
communication formats. The extended formats can
be enabled or disabled at the Format Options, Ext
formats section of the menu:
Extended Formats
(Disable)
The recognition of extended formats can be enabled
by pressing the > button, and can be disabled with
the < button. The default setting is disabled.
The Line Cards can interpret extended formats for
3/1, 3/2, 4/1, 4/2 and 4/3 formats with or without
parity, (the current 3/1/P-3/2-4/1 settings selection
define which formats are valid of the above).
Note:
Using extended formats is not recommended,
because these formats require longer on-line time
than standard formats.
2-way Audio Options
The Line Cards are capable for 2-way Audio
– Listen
In applications. The 2-way Audio Mode can be
disabled or enabled at the 2-way Audio, 2-way Mode
section of the menu
2-way Audio Mode
(Disable)
The 2-way Audio Mode can be enabled by pressing
the > button, and can be disabled with the < button.
The default setting is disabled.
The timeout for the 2-way Audio Mode can be
programmed at the 2-way Audio, 2-way Duration
section:
2-way Timeout
000 x 100 ms
The time can be adjusted by 100 milliseconds from 0
to 256. The default value is 0 which means that there
is no timeout defined, and the 2-way Audio Mode can
be terminated only by the central station operator.
There are different ways to initiate the 2-way Audio
Mode. Certain formats, for example SIA, have
dedicated event codes to enter Listen-In Mode. For
other formats, dedicated account and event groups
can be defined to activate 2-way Audio Mode. The
event group can be defined at the 2-way Audio, 2-
way on Event section of the menu
