Opto Inputs And Relay Outputs
The
RoadRunner
has four optically isolated inputs and four SPDT relay
outputs, that when combined with Logic Language, can be used to
remotely control external equipment or execute local or remote commands.
Pin-outs for the DB25 connector can be found in the Appendix.
As configured from the factory, each optical input (LL Action) is linked to a
corresponding relay on the far-end codec (LL Event) through ‘Links’.
Toggling the optical input will toggle the relay on the far-end
RoadRunner
or
Prima
series codec. Using Logic Language, you can easily re-define
these factory defaults. You can even set up automatic functions to execute
under certain conditions, such as call received or frame loss.
In addition to controlling the far-end relays from the optical inputs, you
can also control these relays by pressing the buttons 1 through 4 on the
front panel keypad. The far-end relays will toggle for as long as the
buttons are held down. By default, the LEDs R1 through R4 will light
when the local relays are closed, thus giving visual cues. As with the
optical inputs, these factory default functions can be changed using LL.
Please note that there are certain conditions that must be met for the relays
to function:
•
A Far-end
RoadRunner
must be running version 2.00 or later
software
•
A Far-end
CDQ
Prima
or
Prima LT Plus
must be equipped with the
optional relay board
•
Framed communications using any MPEG Layer 2 configuration is
required
•
Both codecs must have the ancillary data mode set to MUX and be
using the same ancillary data format
Hot Keys
Your
RoadRunner
has four user programmable ‘Hot’ keys on the
keypad that can be programmed to execute any single command. The
F1
button has been pre-programmed to load the status screen. The
other function buttons can be programmed as you wish. For example,
you can program a button for decoder independent YES and another
