Quartz Q256-SV System Manual
MANUAL-08
RS232 Connector
The control module has a D9 connector on the front edge to allow serial RS232 communication with a PC.
See the installation section for the pin-out of this connector.
Analogue Reference
There MUST be an analogue reference present to ensure the crosspoint changes occur during the field-
blanking interval. If the reference is missing then the routing will occur asynchronously. The reference must
contain syncs of between 300 mV and 5V when terminated, e.g. colour bars or black burst. If you
experience problems with clean switching then refer to our application note AN-0008.
The reference signal should be connected to the Ref 1 input and this is terminated in 75R. The Q256
supports dual references for combined 525/625 operation and in these systems the Ref 2 connector should
be used for the other reference signal. Note that the dual reference signalling works at a crosspoint module
level. Therefore all 32 outputs from one ‘fin’ must change to the same video reference.
