VISTEK V1693 dual changeover switch
1.
DESCRIPTION
The Vistek V1693 is a dual channel signal changeover unit for switching analogue video, analogue audio, RS
232 or digital audio (AES balanced or unbalanced) signals. It forms part of the V1600 range of interface
products and can be fitted into either a V1606 or V1603 chassis, from which it derives its power and control.
Two types of passive rear module are available:
Rear module, type V16VR3J, uses 3-pin screw terminal connectors. It is usually used for analogue or digital
audio (AES balanced), although can also be used for RS232 and other signal types.
Rear module, type V16VR3K, uses BNC connectors. It is usually used for analogue video or digital audio
(AES unbalanced).
Each changeover switch is implemented using a high quality relay. Unselected inputs have optional
terminations of 50Ω, 75 Ω, 600 Ω or Hi Z. Control inputs can be active low, active high, or isolated, selected
by links on the card.
LEDs on the front panel indicate which input is selected and whether the channel is in local or remote mode.
A manual control switch for each channel also on the module front panel selects Input 1, Remote or Input 2.
Removing a link on the card disables this switch.
Channel selection and local/remote status signals are available as isolated contacts or with a common
connected to 0V. In addition the input remote status signals may be configured to indicate if the relay coil has
failed to operate. The V1693 can be controlled and monitored remotely from Viewfind and/or a V1605 control
panel.
