24 Rear Panel
Composite Video Connectors
Two are provided, one RCA-type phono jack (colored yellow), and one BNC
connector. Each is individually buffered, and can drive a 75-Ohm load.
Sync Generator Output Connector
(DVM2 only)
This output provides a standard 4.1-volt p-p composite sync signal for
synchronizing external equipment. Using this connector, the DVM2 can be used
as the master sync source, eliminating the need for a separate sync generator
1
.
(1) Important Note: On DVM2 units manufactured after March 2003 this
connection is used only to source sync to Alcorn McBride show control
equipment. To synchronize DVM2 units together use an external blackburst
generator, or use the video out (BNC connection) of a DVM2 as a master
source. The final connection of the sync chain should be terminated through a
75-Ohm resistor to ground.
C-Sync Daisy-Chain Connectors
(DVM2 only)
These connections provide a convenient means of slaving the DVM2 to an
external video sync source, and also daisy-chaining that source to the next
device in the line. This input
2
accepts standard 4.1-volt p-p composite sync
signals, as well as video level black burst signals. If the DVM2 is the last device
in a 4.1 volt p-p composite sync daisy chain, the 75 Ohm termination switch
should be set in the “ On” position. Otherwise, the switch should be “ Off”.
(2) Important Note: On DVM2 units manufactured after March 2003 this
connection accepts standard video level signals only. Use an external blackburst
sync signal generator or the video out (on BNC connector) from a DVM2 as the
master sync source.
