Red Light Indicators
The CR and ST 2 (control room and studio) indicators work in parallel
with the CR and ST red light indicators in the central section. An on-air con-
dition is indicated by changing the color of the ‘Frisbee’ symbol next to the
OnAir 1500
label to red (and lighting the central section’s
ON-AIR
indicator).
Interface Indicators The three indicator fields ( CAB , CMS , Router ) show the current status of
the optional interfaces to the CAB (computer assisted broadcast) system such
as a Studer DigiMedia playout system, to the Call Management System, and
to an external router control system. Each of them indicates three different
statuses:
Grayed out – Interface not configured
White on black – Interface configured and active
Bright red on black – Interface configured, but not active.
GUI Function Buttons The function of each of the twelve buttons at the right-hand edge of the screen
is configurable. For each of them, a selection from a pool of various GPIO
(general-purpose inputs/outputs) and other functions (such as talkback desti-
nation selection or level meter tap point selection, as shown left) is possible.
Example:
Three of the buttons may be configured with
ON-AIR
,
HOLD
and
TELEPHONE in order to implement a telephone hybrid remote control over
the GPIOs. In such a case, touching a button generates a short output pulse
on the corresponding control output; the feedback signals from the telephone
hybrid going to the control inputs will highlight the buttons.
