ACC501 1. 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 TCconversion modes.
ACC501 2. Description 2.1 Lemo 5 pin, common industry TC standard Pin 1 Ground 2 TC in, nominal level 100 mV min., DC decoupled 3 Aaton ASCII protocol in/out 4 Tune signal @ 1.92 MHz, (DC in 5 to 12 Volts for Rev. A boards) 5 TC out, TTL level 2.2 IR - Infrared Port For setting compatible Clockit devices and data transfer using Aaton ASCII protocol without the need of linking the units via 5 pin Lemo, typical range 4 ft 2.3 BNC, EXT.
ACC501 2.6 USB 2 Serves as MIDI TC I/O interface for sending MTC (Midi time code) to a DAW. EXT power in, 5 Volts. The Mini B USB ports follow the USB specification. It is recommended to have the Controller powered on with the appropriate operation mode selected when establishing the connection to a computer. Do not connect to two computers simultaneously! 2.7 3.
ACC501 2.9 Keypad The keypad is organized with the menu and command cursors on the right and general editing cursors on the left. These keys can double as hold/log when logging on the fly. There is a red escape key on the left which doubles as an on/off switch and a green enter key on the right. Underneath there are 0-9 number keys in black with secondary functions in red and a shift key on the left. The 4 domed Allen screws protect the keypad surface. 2.
ACC501 3. Getting Started Take the Controller out of its pouch and open the sliding door on the left side. Insert 4 AA cells carefully observing the polarity as indicated on the side panel, the 2 cells in the outer slot facing both positive polarity outwards, the 2 cells in the inner tube positive polarity inwards. Then close the contact hinge and slide the door shut. The controller is designed to interface properly with other products of Ambient Recording's Clockit range.
ACC501 4. Menus 4.1 CONF menu This is a general menu for the controller status and control and monitoring of peripherals. Select option by pressing corresponding number. 1: Display: Change display contrast and default backlight brightness and switch off time. 2: Infrared: Displays transceived ASCII characters, allows for a test and reset. 3: Power supply: Shows voltages at power inputs.
ACC501 5: USB Port Settings: USB Port 1 can be set to: 1. Standard mode (Ambient XDOP): Used for programming and computer connection 2. Sony P2: On the virtual COM Port that appears in your hardware settings when the ACC501 is connected, a Sony P2 protocol is being emulated. Thus the ACC501 can be recognized by editing programs (AVID express, Media Log) as a virtual machine and the time code be used for logging etc.
ACC501 If a ACCSI with GPS receiver is connected to the ACC501, it is powered off by default. “GPS module is switched off” will be displayed in the fields for longitude and latitude: Please note: To save power the GPS module should only be switched on when needed. After switching the GPS module on by pressing key 1, at first the message “Waiting for GPS NMEA data… “ is displayed.
ACC501 4.2 GEN menu In this menu the time code generator parameters can be set. The generator starts from 00:00:00:00 and can be set from the following sources: Press 1, Preset: Set generator from different sources Select 1, RTC: sets generator to internal real time clock Set: time, user (date and or user bits), both Select 2, RESET: sets selected bits to zero and generator starts counting Set: time, user, both.
ACC501 4.3 LTC menu In this menu the internal and the external LTC are shown including frame rate, user bits and time code offset in 1/100 frames. The menus allow various actions to be taken using the internal LTC generator and the external LTC. The EXT LTC can be present on the Lemo input, the 3.5mm mini jack or the accessory socket. Press 1, Send: Connects LTC to all TC out pins A square wave icon appears next to Int.
ACC501 Please note: Time will be lost if Run, Stop is pressed. To retrieve time code reset generator from the aux generator in the GEN menu. Press 0, Lock: Locks out keypad. Release with shift + lock. 4.4 ASCII menu In this menu time code can be sent, received and compared using the Aaton ASCII protocol. This protocol sends and receives ASCII messages about time code and is not a continuous data transfer.
ACC501 4.5 MIDI menu Changes the status of the midi time code (MTC) generator. Press 1, On/Off: Turns the MTC output on or off. Please note: When the MTC generator is "on" a M will appear in the Gen TC line of the LTC menu. Press 0, Lock: Locks out keypad. Release with shift + lock. 4.6 WCLK menu The word clock menu controls the parameters of the word clock and turns the word clock generator on or off. 44.1 KHz to 192 KHz clock rate with pull up and pull down are provided.
ACC501 4.7 TUNE menu This menu is used to tune (calibrate) other Clockit devices or for the Controller to calibrate its reference oscillator to an external source. The internal reference can be tuned to + - 10ppm with a resolution of 0.15 ppm per digit. The tuning number DAC is shown on the display as well as recent tuning history. The tuning process may have to be carried out several times if the tuning error is large (over 4ppm).
ACC501 Press 2, Tune intern: This function allows calibrating the controller’s internal reference oscillator to an external source. Please make sure “tune signal out” is off, i.e. no wave symbol displayed next to “INT” (see command # 3). Press, 1 Ref: Calibrates the controller’s internal oscillator to another Clockit device’s reference signal such as an ACLxx, ACD301, ALL601, a Sound Devices 7’series recorder, an Arri Alexa or other 3rd party products which have a Clockit system built in.
ACC501 Press 3, Tune signal on/off: For board revisions “A” or later: it is now possible to tune one Controller from another. The reference Controller has to send out the “Tune signal”, a 1.92 MHz clock. When Tune signal out is “on”, a little wave symbol is displayed next to “INT” Toggle “on – off” by pressing key 3. Please note: When Tune signal out is “on”, external devices can not be tuned, nor does “Tune intern” function.
ACC501 5. Technical Data: Powering: Batteries: 4x AA-battery (Mignon-battery, each 1.5V) Extern power via Lemo-connector: max. 12Volt Pin 1: Ground, Pin 4: DC 5 –12 Volt Via USB-connector Connectors: LEMO 5pin, FGG/JGG.0B.305.CLADxx(ZN) Pin 1: Ground Pin 2: TC in, nominal level 100 mV min., DC decoupled Pin 3: Aaton ASCII protocol in/out Pin 4: Tune signal @ 1.92 MHz or ext. power max.
