Tally Interface Unit
The BKDS-7700 Tally Interface Unit provides 72 standard programmed tally relay
outputs for the following switcher components:
•
All 36 primary inputs
•
4 Analog Chroma Key inputs
•
Up to 6 DME/DVE inputs
•
Up to 48 External Devices
The unit can also be used to set conditional tallys for ISO record and other switcher
functions. Up to 4 relay states may be set for each tally function. The BKDS-7700
also provides an "S-Bus" interface to the Sony DVS "B" series routing switchers. In
this configuration, the "B" series is accessed directly from the DVS-7200's display
for changing primary switcher crosspoints. Input labels and tally information
automatically follows all routing switcher changes.
Note that the BKDS-7700 is a separate rack mount chassis (3 RU) with power, and
connects to the DVS-7200 via RS-422. Note that RS-422 interconnect cables are
not provided. In the "Options and Upgrades" section, see the "System Cables,
RS-422" heading for part numbers and information. RS-422 interconnect cables
have a maximum length of 100 meters.
Tally Interface Software
The BKDS-7720 Tally Interface Software is required for the BKDS-7700 Tally
Interface Unit and router interface. Note that this software is installed with a PC,
using an RS-232C interconnect cable (both items user-supplied).
Expansion Module
The BKDS-7701 Expansion Module option, when installed in the BKDS-7700,
increases the number of relay (tally) outputs from 72 to 216.
Redundant Power Supply — Tally
The BKDS-7790 Redundant Power Supply (with mounting hardware and
interconnect cables) provides an auto-switching power source for the BKDS-7700
Tally Interface Unit.
