TG Jumper Block
Domino boards have TG jumper blocks called TGX when associated to the Camera X connector and TGY when associated to the Camera Y connector. These jumper blocks can be seen as a set of four independent jumpers.
TG jumper block
The TG jumper block are used to configure the usage of the following camera connector pins.

- The "T" jumpers control the video lane termination.
- The T1 jumper connects a 75 Ω resistor between V1+ and V1- signals.
- The T2 jumper is not used.
- The "G" jumpers control the grounding of the return video lane.
- The G1 jumper connects V1- signal to bracket ground.
- The G2 jumper is not used.
Differential terminated video signal (default setting)
This configuration is highly recommended when the video input is available in the form of an individual coaxial cable. The cable inner conductor should be applied to V1+ and the outer conductor (shield) should be connected to V1-.
The cable is terminated by an internal 75 Ω resistor.
The MultiCam parameter JumperL1 returns DT when a supported camera requires this configuration.
Differential unterminated video signal
For system dependent reasons, it may be needed to remove the internal 75 Ω termination resistor.
The MultiCam parameter JumperL1 returns DU when a supported camera requires this configuration.
Single-ended terminated video signal
This configuration is recommended when there is no separate return path for the video signal.
The video signal is applied to V1+. V1- is directly linked to the connector ground. The 75 Ω termination resistor is internally connected.
The MultiCam parameter JumperL1 returns ST when a supported camera requires this configuration.
Single-ended unterminated video signal
This configuration is recommended when there is no separate return path for the video signal.
The video signal is applied to V1+. V1- is directly linked to the connector ground. The 75 Ω termination resistor is not connected.
The MultiCam parameter JumperL1 returns SU when a supported camera requires this configuration.
