3DESCRIPTION
The LTC 8785 Series are control code converters that convert Allegiant® series “variable speed” biphase control codes into “fixed speed” biphase control codes.
When AutoDome® pan/tilt/zoom cameras are added to existing Allegiant systems, it is usually preferable to operate them in their variable speed mode. The
LTC 8553/00 and LTC 8555/00 keyboards containing proportional joysticks must be added to the system along with an upgrade of the system CPU so the new variable speed control codes can be generated. If the existing system contains older type TC8561 Series receiver/drivers, there will be a code compatibility problem. The older TC8561 Series receiver/drivers were only designed to operate using “fixed speed” control codes and will not function when the newer variable speed codes are being received. To solve this problem, the LTC 8785 Series code converters have been designed to maintain a source of “fixed speed” control codes in this type of system.
The LTC 8785 Series provide 32 separate outputs for driving up to 256 existing TC8561 Series Receiver/Drivers. Either “star" or “daisy chain" wiring configurations may be used. Each output is capable of driving up to 8 receiver/drivers in a “daisy chain” configuration up to 1500 meters (5000 ft) using 1 mm2 (Belden 8760 or equivalent 18 AWG) shielded twisted pair. A 2 meter (6 ft) data cable for interface to the existing Allegiant LTC 8568/00 Signal Distribution Unit is supplied. The unit will also accept control code supplied from LTC 8569 Series, LTC 8571 Series, or LTC 8572 Series Code Merger units.
