1. DESCRIPTION
The VistekV1693 is a dual channel signal changeoverunit forswitching analogue video, analogue audio, RS
232 ordigital audio (AES balanced or unbalanced) signals. It formspart ofthe V1600 range ofinterface
productsand can be fitted into either a V1606 or V1603 chassis, fromwhich it derives its powerand control.
Two types ofpassive rear module are available:
Rearmodule, type V16VR3J, uses3-pin screw terminal connectors. It isusuallyused foranalogue or digital
audio (AES balanced), although can also be used for RS232 and other signal types.
Rearmodule, type V16VR3K, usesBNC connectors. It isusuallyused foranalogue video or digital audio
(AES unbalanced).
Each changeoverswitch isimplemented using a high qualityrelay. Unselected inputs have optional
terminationsof 50 , 75 , 600 orHi Z. Control inputscan be active low, active high, orisolated, selected
bylinks on the card.
LEDs on the front panel indicate which input is selected and whether the channel isin local orremote mode.
A manual control switch for each channel also on the module front panelselectsInput 1, Remote orInput 2.
Removing a linkon the card disables this switch.
Channel selection and local/remote status signalsare available asisolated contacts orwith a common
connected to 0V. In addition the input remote status signalsmaybe configured to indicate ifthe relaycoilhas
failed to operate. The V1693 can be controlled and monitored remotelyfromViewfind and/ora V1605 control
panel.

3.2 Configuration
Configuration ofthe V1693 consistsof positioning links JP1 – JP26 to set the following for each channel:
• Remote control input active high/active low/isolated.
• Front panel signal changeovercontrol and associated remote/local indications enabled/disabled.
• Derivation ofinput selection tallies.
• Input selection and local/remote talliesto be grounded common or ground-free.
The functions ofthese links are described in detail in Section 2.2.
3.3 Remote Control
The V1693 has two remote control options:
• Contact closureor 12V (dependent on configuration) applied to the remote control port routesthe output
ofa channel to Input 2. The output isrouted to Input 1 in the absence of a control input.
• Control over DARTnet fromaV1605 orViewfind controller when the unit isfitted into aDART-equipped
V1606 or V1603 rack.
