Introduction Cooke Optics Limited developed the/I Technology system to enable film and digital cameras and equipment to automatically record and display key lens data for every frame shot. Lens metadata includes information such as focal length, focus distance, Tstop, Zoom, depth of field, horizontal field of view, entrance pupil position and frame rate. Script supervisors no longer need to manually write down lens setting for every frame shot.
2. Cooke /I “Intelligent” Technology Overview /I Technology is a registered trademark of Cooke Optics Limited. It is a metadata protocol that enables film and digital cameras to automatically record key lens data for every frame shot. Equipment identification is by serial number, lens type and manufacturer.
/I Technology CORE Commands and EXTENDED Commands Figure 1 2.2 /I Technology Partners Digital cameras that are I equipped (RED, SI 2K, Sony F35, F3, F65) and film cameras (Aaton Penelope, Arricams) talk to I lenses directly via contacts in their lens mounts. Transvideo monitors have built-in I Technology that can display lens data in real time along with a graphic representation of the iris, focus and depth-of-field. Metadata is passed through to post-production to improve VFX creation and DI calibration.

3. Hardware 3.1 Interface Requirements Some I lenses have both a camera communication connector (four contacts built in the PL mount as shown in figure 2) and an external communication connector (figures 3 and 4). Some lenses have only the camera communication interface. Each interface is described in detail in Sections 3.1.2 and 3.1.3. 3.1.1 Power Power can be supplied to the lens through either the camera connector or an external connector (if available) or both.

3.2 Lens System Components 3.2.1 Lens System Overview The Cooke I Technology lens system contains resistance elements to sense ring positions, an electronics board to process and calculate lens information, and one or two serial communications interfaces to receive and send commands and data to a camera and/or other external device. Cooke 5I lenses also have two sets of LEDs used to illuminate the focus scale. The LEDs are connected to a secondary electronics interface board.
4. System Communications 4.1 Basic Communications Format Standard serial communication is 8 bit data without parity, 1 stop bit in ACSII format. The lens can also transmit a packed binary format response when requested, using the 8 bit no parity format, to reduce the time taken to transmit data from the lens. The camera or external unit will initiate all data transfers from the lens except during Power-Up.
Typically, a lens will start-up at a baud rate of 115k2 and send the powerup string, <[l/f][c/r/], (less-than symbol followed by a linefeed and carriage return), when power is detected. The lens will then wait for one second to receive an N command from a controlling channel. If the N command is not received within one second, the baud rate will drop to 9600 and the lens will wait until an N command is received. The lens must receive an N command as the first command.
4.4 Update Ownership Program for Cooke I Lenses The Cooke Owner Update program can be used to change the owner name stored in the lens through its external interface. The program runs on Windows and MAC OS X platforms and can be downloaded from the Cooke Optics website at: http://www.cookeoptics.com/cooke.nsf/technical/downloads.html The lens is connected to the PC or MAC through a serial port. If the computer does not have a serial port, use a USB-Serial port adapter and install the correct driver.
external interface or both. This data can then be stored by the camera or external device for post processing. 5I lenses have the additional facility to collect a data stream from an External Data Source Unit (EDSU) and then append this data to the normally generated data string of the lens. This combined data string is then sent to the camera. At the same time that the EDSU is sending data to the lens, it can also request that the lens send the normal data stream back to it.
9600 baud and the lens will wait without timeout for an N command. Baud rate can be adjusted using the Kbn command. All CORE commands described in Sections 5.1 through 5.1.18 are available for PanchroI lenses. 4.7.2 S4I Prime and CXX 15-40mm Zoom T2.0 Lenses S4I lenses have two communications channels which send the same response to both channels and can receive commands only from a single controlling channel.
This data can be stored by the camera or external equipment for recording and subsequent post processing. A set of additional functions are available to 5I lenses which allow them to receive an externally generated data string and then append this received data to the normally generated data stream of the lens before it is sent to the camera. A unit which sends data to a 5I lens through its external interface is called an “External Data Source Unit” or EDSU. Operation with an EDSU is described in Section 9.
interface, the external interface will have control. Thus, the camera interface will have control only when there is no power supplied to the external interface. Some commands have been introduced with newer firmware versions and may not be available if their firmware has not yet been upgraded. Note also, that certain commands pertain only to 5I lenses.

on prompt. The lens will then wait for one second to receive an N command from a controlling channel. If the N command is not received within one second, the baud rate will drop to 9600 and the lens power-on string will be sent again. The lens will then wait until an N command is received. The lens must receive an N command as the first command. Once the lens has received and responded to the N command, all other commands (valid for that lens type) are available to the controlling channel(s).
If a valid Bluetooth connection is established, the baud rate will remain at 9600 and the lens will wait for the N command. The Baud rate must remain at 9600 once a Bluetooth link is established, so any command to change baud rate at this point will receive the error response. In the event a Bluetooth connection is not established correctly within one second, the lens will issue a standard startup string (<) and wait until an N command is received from the external interface.
5. CORE Command Set 5.1 CORE Commands for All Lens Types Commands to a lens are in ASCII format and terminate with a carriage return character. Responses from a lens are in either ASCII format or packed binary format and terminate with the character pair, linefeed carriage-return: [l/f][c/r]. 5.1.1 N Command: Retrieve Fixed Data in ASCII Format: Typical Response (see exceptions by Lens type) The first command a lens receives must be the N command.

6. Measurement and Calculation Units 6.1 Measured Values and Calculated Values Cooke/I lenses measure the lens settings (focus, aperture, zoom) and use these values to calculate focal length, hyperfocal distance, near focus distance, far focus distance, horizontal field of view, entrance pupil position, normalized focus distance and normalized zoom setting. Distance values are expressed in either millimeters or in multiples of 0.
the default display units set as imperial. If the value after Tag U is a ‘b’, the calibration table stores focus distances in both imperial and metric units with the default display units set as metric. 6.2.2 Cooke 5I Lens Units and Startup Units Commands 5I lenses have a dual marked focus ring that can be reversed to show either imperial or metric units. 5I lenses have been factory calibrated in both imperial and metric units and the factory set Start-Up Units should match the focus ring units.
7. Baud Rates and Response Times 7.1 Implementation – PANCHROI, RED & S4I Zooms; S4I Primes; 5I Primes Message transmission time is affected by the length of the data stream and baud rate. Earlier S4I Prime and Zoom lenses with 10-bit ADC have slower clock speeds than the later S4I Primes lenses with 12-bit ADC. 7.2 Table 6: Compare Calculation Time to Lens Type Lens Type 5I Prime PanchroI Prime S4I Prime S4I Prime S4I Zoom S4I Zoom RED 7.

8. Illumination Scale – 5I Lenses 8.1 Overview 5I lenses are equipped with two sets of LED’s which can controlled to illuminate the scales in low light situations. The brightness level of one set can be altered while the other is OFF, or both sets can be altered in unison. Manual Control of the brightness levels is achieved using the Aperture Ring. The brightness levels can also be controlled remotely by using the 5I Lighting Control Unit or issuing the Kjn or Kkn Commands. 8.1.
1. 2. 3. 4. While pressing “ – “ , connect the power cable All LEDs are highlighted. Release “ – “ The module starts normally with LEDs off on the unit. SPECIAL MODE: Adjust The Maximum Brightness Of The Yellow LEDs 1. 2. 3. 4. During normal use, press ZONE until the green LED brightness increases. By keeping ZONE pressed, the Green LED becomes very bright.
during which “no change of Aperture setting” is detected, the “set illumination level” is retained. During this illumination setting process, I lens operations continue to function normally. To alter the brightness of one set of LEDs, move the Aperture ring to the aperture setting T1.4 end-stop and move it away towards T22, then repeat that process twice more within 0.5 second. This will cause the LED’s to be set to OFF for 0.3 sec, then ON for 0.3 sec, then OFF again.
9. External DATA Source Unit (EDSU) – 5I 9.1 Overview Cooke 5I lenses have additional capabilities and commands, not available to the other lens types, which enable an external device, (called an External Data Source Unit or EDSU,) connected to the external RS232 channel of the lens, to perform special operations. Under normal operation, a command is sent to a lens requesting information, the lens generates a data string and sends this information to the camera interface, the external interface or both.
6. Each time EDSU generates new data, it issues OD command to send data. This data is stored in lens in EDSU buffer. (When new string is received by lens, it replaces existing EDSU contents with new string.) 7. The lens generates data strings at whatever rate is required (single or continuous) and uses the latest EDSU data to append. 8. To terminate the process, the EDSU sends OH command.
P V Retrieve board temperature Set/Change film size Wnn Change film size X Y Change units to Imperial Change Units to Metric Allow Beware (Interlock exists for Camera priority) Beware (Interlock exists for Camera priority) Beware Beware To avoid potential conflicts that may arise if commands are issued by multiple sources, the EDSU should monitor any commands allowed to pass-through to the lens to verify commands meet lens specifications and do not cause conflict with current EDSU operation. .
11. NEW Optional Commands: Retrieve UserDefined Combinations of Binary Data Packets 11.1 NEW Optional Commands - Planned for 2013 The New optional commands will allow users to define and then retrieve optional binary data sets composed of user-selected lens information combined in any order. Each lens data element will have a unique tag. By stringing together a list of tags, users can request only the lens data elements they need in whatever order they want.
