Caution
Repeating frames using the transmission mode feature is a
function implemented in software; there is a time gap of
about 50ms between each transmission of the entire
specification. Use Repeat Frames ‘n’ Times or Bursts
where timing issues are critical when sending frames for
these devices.
Ways of repeating frames can be used together. For example, assume the following
two streams are defined:
Stream 1; packet gap=100msec, burst count=4, burst
gap=4msec,
repeat frame 2 times
Stream 2; packet gap=200msec, no burst
The example results in the following:
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 104msec
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 100msec
Transmit Stream 1
Wait 104msec
Transmit Stream 2
Wait 200msec
If the transmission mode is set to continuous, the entire sequence above is repeated
until the module is stopped.
The
Repeat Stream field sets how many times to repeat the current stream. For
example, if the
Repeat Stream field is set to a value of 8, the current stream would
be sent 8 times before the next stream in the Transmit Specification is sent.
