Clock One / Digit Tally Information
Telescript's Clock One can be integrated into many of Telescript's prompting systems. It features dual colour digits (green/red), and LTC input and displays time of day. This clock can work alongide our Digit Tally and will simultaneously change colours with the Tally.
LTC (Longitudinal Time Code) input is a standard XLR3 female that accepts a balanced or unbalanced signal between 50mV and 2 Vpp. Pin 1 is ground, a balanced signal is applied between pins 2 and 3, and an unbalanced signal ma be applied between either pin 2 or pin 3 and ground.
The DC power input jack accepts a standard 2.1mm plug with centre positive. Input power is nominally 12VDC at 1.2 amps maximum.
The Sensor 3.5mm jack accepts an optical sensor or contact closure to ground. Low illumination or open contact condition displays green digits. High illumination (such as when a tally light is on) or a closed input contact (such as from another clock or tally digit) causes the display digits to turn red.
The repeat 3.5mm jack provides a contact closure to ground when digit display is red. This output can be used to drive the sensor input on another device such as a Digit Tally or another clock, allowing daisy chaining of multiple devices from a single optical sensor or contact closure source.
Digit Tally's use the same DC input connector as the clock. Maximum current draw is 150 milliamps. The same 3.5mm jacks are likewise present.
Connect the provided light sensor to the sensor input on the tally. Then place the sensor end over the tally light on your camera. Make sure all light is completely clocked out from the sensor or else the sensor will have difficulty sensing light changes on the camera tally.
Connect the provided 3.5mm cable to the Repeat input and plug it into the sensor input on the Clock One.
The Adjust dial on both units controls the sensors sensitivity to ambient light.
