H Jumper Block

Domino boards have H jumper blocks called HX when associated to the Camera X connector and HY when associated to the Camera Y connector.

The H jumper blocks are used to configure the usage of the following camera connector pins.

Pin number

Generic name

Name on camera connector

14

HIO

GATE

GATE

TTL input/output (default setting)

This configuration is used to control HIO and GATE signals as 2 independent TTL I/O lines. The direction and polarity of these two signals is determined through relevant MultiCam parameters.

The MultiCam parameter JumperH returns TTL when a supported camera requires this configuration.

JumpersTTL

Non-inverted differential horizontal reference

This configuration is used to control HIO and GATE pins as a single non-inverted differential input line. The direction and polarity of these two signals is determined through relevant MultiCam parameters.

The positive line is connected to the HIO pin and the negative line is connected to the GATE pin.

The MultiCam parameter JumperH returns DPOS when a supported camera requires this configuration.

JumpersDPOS

Inverted differential horizontal reference

This configuration is used to control HIO and GATE pins as a single inverted differential input line. The direction and polarity of these two signals is determined through relevant MultiCam parameters.

The positive line is connected to the GATE pin and the negative line is connected to the HIO pin.

The MultiCam parameter JumperH returns DNEG when a supported camera requires this configuration.
