7	c FRAME REFERECE IN/OUT connectors (BNC
	type)
	The IN connector is used to receive an HD tri-level

reference sync signal or SD reference sync signal (black burst signal) for frame sequence lock between camera control units. In this case, the signal supplied to the IN signal is output from the OUT connector as-is. When this unit is used as the master unit, these connectors can be used as the frame sync pulse

7-3-8HKCU-904 Line Converter Unit

The optional HKCU-904 is to be installed in the HDCU- 900 expansion slot or in place of the SD signal input/ output block.

1 SERIAL RET INPUT 1-4 connectors

output connectors for pull down. Switching is made using the switches on the internal FC board.

dSERIAL OUTPUT 1 to 3 and MONI (monitor) connectors (BNC type)

The 1 to 3 connectors output the signal from the camera as three HD-SDI signals. The MONI connector outputs the signal from the video camera mixed with skin tone gate signals and some aspect marker signal in HD-SDI format.

Note

When used in combination with the HKCU-903, mount the HKCU-903 into the second slot from the top, and the HKCU-904 into the third slot.

aSERIAL RET INPUT 1-4 (HD-SDI return video 1,

2, 3, and 4 input) connectors (BNC type)

Four different HD-SDI analog return video input signals (720/60P) may be received independently. The selection of RET 1, 2, 3, or 4 is made by the camera’s return switch. The type of input signal on RET 1, 2, 3, and 4 may be set individually using switches on the AT board in the HDCU-900, or using the MSU-700A/ 750 Master Setup Unit.

bSYNC OUT (HD/SD sync signal output)

connectors (BNC type)

The left connector outputs a sync signal of the same format as that of the input/output block in the above slot. The right connector outputs the HD tri-level sync signal of the same format as that of the SERIAL OUTPUT 1 to 3 connectors.

cSERIAL OUTPUT 1 to 3 connectors (BNC type) The 1 to 3 connectors output the signal from the camera as three HD-SDI signals (720/60P).
