This equipment is part of the old monitoring equipment that I am now disposing of...
Analog Composite Video Signal Sequential Switcher
Unbranded on the case or inside however this was an Intellisense supplied product
Country of origin is likely to be China
Dates from around the 1980's
All discrete control electronics
Eight video inputs (BNC)
Single video output (BNC)
AC 240V power input via wired lead.
Dimensions: 220mm x 220mm x 60mm high
FUNCTION:
These boxes are really useful if you are using multiple analog composite video sources and need to view any ONE of these sources at a time
This equipment is very basic in function and it is not designed to provide facilities such as multi-screen or "stop on video" control
Each channel has a lever switch associated with it - and a RED LED
In the upwards switch position, that channel is removed from any sequential switching - for example, instead of running 1-2-3-4-5-6-7-8 but you then flipped channel 5 up, the sequence becomes 1-2-3-4-6-7-8
In the central switch position, the channel is actively able to be sequentially switched
In the lower switch position, the channel is permanently ON - all sequential switching will stop
The control to the right of the front panel is the ON-OFF button and also the auto switching speed control
The switching occurs regardless of whether there is video at the channel input i.e it is not a system that can detect video and only then enable the channel.
Suits Mono or Colour
COSMETIC CONDITION:
Excellent condition - all steel case
All LED's work
All channel toggle switches work
Power on-off control works
No damage to the casing at all
TESTING:
I ran multiple source composite video through this box (cameras and DVD players) and checked that all channels "came alive" when the RED LED was lit up.
I also checked the functions of the channel toggle control operated as designed
Speed of auto switching was also checked
No issues with this equipment at all - all tests passed
