TX500 series technical manual
the DVE is taken to air, the active picture to PGM output is taken from the DVE path. All
ancillary data is taken from the delay path, unaltered.
It is recommended that the second DVE output is taken directly to a monitor, or that it
appears as a source on the router which is accessible from the AUX bus (input 21 to 24)
enabling it to be selected and the DVE sequences previewed before use.
Note:
The audio mixer card (5029) is fitted with the ability to set an equivalent audio delay to
compensate for the DVE delay. This is set by a HEX switch (see section 5.1.10).
Internal DVE
If the TX500 system is fitted with an internal ICON DVE module (3426) and/or an internal
Frame Store (3403), a 1448 rear panel will be fitted to the main frame, on which all
connections will be available, as follows:
FRAMESTORE
OUT
1448
PGM
PVW

The NETWORK port is for connection to a TCP/IP LAN where Pro-Bels DVE Move Editor
may be used to create and edit sequences. See the 3426 DVE User Guide (HU-3426-DVE)
for full details on this product.
If a Framestore module is fitted, the
FRAMESTORE IN and OUT
connections are made to the main
TX500 rear panel (TO and FROM
FRAMESTORE). FGND1 is connected
to the TX500 ‘TO DVE’, and PGM to
‘FROM DVE’. BGRND and FGND2 are
for the customers use. PVW may be
used to rehearse moves by plugging it
to a spare monitoring point.
A loop-through video reference is
required. The RS485 port is connected
to the TX500 DVE breakout control
cable.
