Show Selection
- Some dual hybrid interface units can be operated in a dual studio
mode, where the two hybrids are used independently in two studios. In these cases
Desktop Directors may choose from "
Show 1
" (hybrid 1) or "
Show 2
" (hybrid 2). If
your system is configured for one of the dual modes you can use the following
shortcuts to change the
Show
being controlled by a specific Call Controller:
•
*74691 (*SHOW1)
•
*74692 (*SHOW2)
NOTE: When the Call Controller is used with the Series 2101 it cannot choose a
show. However, a Desktop Director can be used to select the show being used on
that 2101 Studio Interface, and all Call Controllers, Console Directors and Desktop
Directors connected to that Studio Interface will, of course, be associated with that
show as well.
3 Connections
Connecting the Call Controller to your Telos Talkshow system is identical to connecting
a Desktop Director, as covered in your Telos Talkshow system manual. This jack is
labeled
Telos Interface
and the connection is made using an 8- pin miniature modular
cable (RJ- 45 style) provided with the unit. An LED adjacent to this jack will illuminate
continuously if the connection is correct.
In cases where two Telos control units share the same Desktop Director port on the
Talkshow system, one unit will need to have its termination resistors disabled (units are
shipped with the terminators enabled). To do so, remove the unit's cover by removing
the screws around the edge of the black metal cover. Inside locate two 3- pin headers,
labeled "JP- 1" and "JP- 2" and move the jumper blocks top the alternate positions for
both jumpers. Replace the cover and screws.
The connection to the telephone set is made using a standard 6- position 2- pin
miniature modular cable (RJ- 11 style) to the jack on the unit labeled
Telephone Set
. The
center two pins are used. If your Telephone does not use this type of connector an
adaptor may be purchased locally.
4 Telephone Set Interface
Most analog telephone sets intended for use with standard analog "POTS" line will work
with the Call Controller for basic operation. The "Telephone Set" jack provides a signal
that emulates a USA analog telephone line as follows (for more detailed information see
TIA/EIA- 464- B):
Loop Specifications:
Loop Current - 25 mA
Loop Voltage - 48 VDC
Ringer Specifications:
Configuration - Metallic (line to line)
Voltage/Frequency - 20 Hz/ 51 Volts RMS (Sine)
Max Ringer Equivalence - 2 REN
