Inputs
Links 1 - 8 (J2), Links 9-16 (J3), Links 17 – 25 (J5), Links 25-32 (J6)
Selects 75ohm termination for the video inputs. Input link 1, when fitted terminates video input
channel 1, Input link 2 provides termination for channel 2 and so on, up to 32 channels. The
illustration below shows how the input links are marked on the VisionSwitch32-H card
.
Note:
The removal of the link disables the 75ohm video termination from the selected input
channel. However, a secondary termination of 4.7kohms remains allowing the
VisionSwitch32-H to be used with 2VRMS audio signal inputs. When using the
VisionSwitch32-H with audio signals it is therefore recommended that corresponding input
links are removed.
Outputs
Links 1 – 8 (J14), Links 9-16 (J15), Links 17-24 (J20), Links 25-32 (J21)
Selects 75ohm termination for the video outputs. Output link 1 when fitted terminates video output
channel 1. Output link 2 provides termination for output channel 2 and so on, up to 32 channels.
The following illustration shows how the output links are marked on the VisionSwitch32-H card.
All VisionSwitch32-H cards are shipped with all links fitted.
