FRAME CONTENTS...
Opens a window to determine the contents of up to 128 frames.
Each frame is represented by one character. These characters can be set
to the following values:
A: alphanumeric message
B: binary message
F: filler frame, contains FLEX structures but no messages
identical with <blank>
I: instruction for SSID subscriber units
N: numeric message
O: frame without FLEX structures ("other")
P: special numeric message
R: Emergency Resync Frame, as defined in the FLEX standard
S: Secure Message
T: tone-only message
X: the message type is defined by the value of CATEGORY
<blank>:
same as F’
lower case letter:
same as upper case letters but as a "message to all subscribers".
Not all message types can be sent as "message to all subscribers"
so that not all lower case letters exist.
X and blank may be used in order to permit the AUTO ADJUST
mechanism (see above) to change this entry.
Notes: - The SYSTEM COLLAPSE VALUE may cause the pager to
respond to much more than only its "own" frame.
- After *RST a character is set in the editor window for each of
the 128 frames. It is possible, however, to clear characters by
means of the BACKSPACE key. Correspondingly less than
128 frames are then output per cycle. Thus it is possible, for
instance, to generate a three-frame test sequence if only the
characters for the first three frames are output.
IEC-bus command: :SOUR:FLEX:FCON "O,X,A"
RECALCULATE
Triggers a recalculation of the generated FLEX telegram. This action has
to be triggered each time a parameter has been changed.
Exception: MESSAGE GENERATION MODE.
IEC-bus command: :SOUR:FLEX:STAT OFF; STAT ON
MODE
Selection of sequence of useful and filler frames.
ALWAYS The frames are continuously output according to the setting
under FRAME CONTENTS.
IEC-bus command: :TRIG:DM:SOUR AUTO
SINGLE Only FLEX filler data are output. If EXECUTE SINGLE
is
selected, the subsequent frame is output in the way it has
been set under FRAME CONTENTS.
IEC-bus command: :TRIG:DM:SOUR SING
:SOUR:FLEX:TACT MESS
EXT Only FLEX filler data are output. In the case of an external
trigger pulse, the subsequent frame is output in the way it has
been set under FRAME CONTENTS.
IEC-bus command: :TRIG:DM:SOUR EXT
:SOUR:FLEX:TACT MESS
