Introduction
Superseding the ACC101 the Clockit Controller ACC501 retains all its functions and serves as a general
purpose TC master unit which can read, generate and compare and tune to all kind of TC rates.
It offers a variety of addtional features such as word clock output, dual TC display, enhanced GPS
modes and multiple I/O ports including USB ports for PC/Mac connectivity and TC-conversion modes.
Although roughly half of the size of its predecessor the user interface has been vastly improved using a
graphical display and an enhanced keypad with dual navigational cursor pads for easy two-handed
operation.
Power can be provided over internal batteries, USB or an external source. One load of 4 good quality
alkaline AA cells should achieve over 24 hrs. of continuous use (depending on activity and brightness of
display backlight), and many days in a typical scenario of intermittent use. For increased battery lifetime
a special standby mode has been implemented. While the main MCU controls the main timecode
generator, keypad, display and memory functions, a special low-power MCU monitors the power
converters and an auxiliary generator is maintaining frame accurate timecode when put in standby for
the full battery life of the Controller (one week or more).
To allow for even more flexible implementation of future enhancements, the hardware has been
purposely designed to cater for new features without major hardware updates.
User-manageable software updates will become available from the product page on
https://dl.dropboxusercontent.com/u/105377880/Firmware/Firmware1.10.zip
so please check back for software updates and change logs.
Updating the software is done via a Windows PC over USB running a dedicated programming tool also
available from the aforementioned source.
