RCA LDK 5481, LDK 4700 Stand alone SDI coax configuration, Stand alone multicore configuration

1.4.3 Stand alone SDI coax configuration

A camera head with an LDK 5481/00 adapter can be connected to a recorder unit using an SDI coax cable. Only the SDI signal is passed via the coax cable. The maximum length of cable that can be used is 300 m (1000 ft). High quality coax cable should be used (for example, Belden 1694A). The DC power supply for the camera is supplied directly to the adapter.

1.4.4 Stand alone multicore configuration

A camera head with an LDK 5481/00 adapter can be connected to a recorder using a multicore cable. Power can be supplied by the recorder via the multicore cable or directly to the adapter itself. To avoid degradation in the video signal, the maximum cable length is restricted to 5 m (17 ft) when the component outputs are used in the recorder.

If the recorder uses the SDI signals, then the maximum length of cable depends on the ability of the recorder unit to supply sufficient power to the camera. When the adapter is powered directly the maximum length is 100 m (330 ft). With minimum power supplied from the recorder unit the maximum length is 25 m (80 ft).

☞Note

Always use a listed 26-pin CCZ-A multicore cable compliant with EBU N21 (for example, Draka multicore camera cable type 755-2 PVC)
