Operating CQX Routers
CQX Routers
The “clean and quiet” (CQX) control panel is used with the CQX router. It has 4 dedicated transi-
tion type buttons (cut, v-fade, cut-fade, and fade-cut) and 3 dedicated transition rate buttons
(slow, medium, and fast).
The transition buttons appear in this ordering:
The panel is not configurable at present. (A slow transition is fixed at 3 seconds; medium, at 2
seconds; and fast, at 1 second. A cut transition is instantaneous for video; the audio ramps down
over 3 frames and ramps back up over 3 frames. See
CQX Transition Rates on page 169 for more
detail.)
At present, the concept of levels does not apply to the CQX router.
The router can be used with a captive panel (mounted on the router) or a remote panel
(mounted on a remote panel module and connected to the router through an Ethernet switch).
(It is possible to control the router using an third-party automation system but this document
does not address automation.)
The CQX router models each have 2 CQX outputs and 6 auxiliary outputs. The CQX outputs
exhibit smooth transitions. The auxiliary outputs are “normal” outputs.
The CQX router models also have 2 bypass video inputs in addition to the 16 video inputs. The
bypass inputs become active if the router loses power. The bypass relay switches when it loses
power, causing the bypass video sources to be routed to the CQX outputs.
The CQX router models each have a GPIO connector (DB25) that supports 16 TTL-level inputs
and 4 high-power outputs, all optically isolated. Each of the 16 GP inputs switches a corre-
sponding video input to CQ output 1. The GP outputs represent status and alarms.
