4.7 = 6 buffered, RETIMER, Idle mode
as mode
5
, but Idle mode in case of no DMX512 signal.
4.8 =
7 buffered, RETIMER, DMX values = zero
as mode
5
, but all DMX512 values becomes zero in case of no
DMX512 signal.
4.9 =
8 buffered, RETIMER, hold last values
as mode
5
, but with data hold of last DMX frame in case of no
DMX512 signal.
4.10 =
9 reserved for optional functions
5. RETIMER
The DMX512 data are processed by the SP1X12 interface with an
optimal and standard compliant DMX512 timing (as recommended
in USITT DMX512A, American National Standard E1.11–2004 /
8.11 table 6 & 7 and DIN 56930-2 / 4.4.1.).
This means a DMX512 receiver must be able to accept:
44 frames per second, no additional bit between the bytes [slots],
no additional time between the frames [packets].
Unfortunately, there are DMX512 devices on the market marked
with DMX512 but are not able to receive and to process a DMX512
signal with an optimal and standard-compliant timing. This results in
flickering and black outs.
In this case the SP1X12 includes a RETIMER with a standard fix
timing added to the modes 5 to 8.
