1.4.2DigiLink system multicore configuration

A camera head with an LDK 5481/00 adapter can be connected to the LDK 4700/10 base unit using multicore cable. The maximum length of cable that can be used is 75 m (250 ft). The base unit can supply power for the camera via the multicore cable. The power consumption of the camera may reduce the maximum length of cable that can be used, so alternatively, the power for the camera can be supplied directly to the adapter from the optional LDK 5901 power supply.
