Shutter control cables should now only be strictly necessary for earlier models. The newer DSLRs can also be used with the control cables, but this should only be required where the software you. USB based control. The popular Images. Plus. astrophotography software has been updated to support USB based control. The TC 8. 0N3 hack detailed below for intervalometer support with consumer range DSLRs is still relevant for the newer models. Canon DSLR models that require the control cable for computer control of long exposures include. EOS 3. 00. DRebel, 3. DXT, 4. 00. DXti, 1. D, 2. 0D, 2. 0Da, 3. D, 5. D, 1. D, 1. Ds, 1. D Mk. II, and 1. Ds Mk. II. Canon DSLRs including, and later than, the following incorporate USB based long exposure control. DXS, 4. 50. DXSi, 5. DT1i, 4. 0D, 5. 0D, 5. D Mk. II, 1. D Mk. III. While we are on this subject other features that Canon could easily add software support for include. SDK. These would be incredibly useful for astrophotography. Introduction. The following describes the design and construction of serial port based cables. Canon digital SLRs. The motivation behind the development of the cables was to support the use of Canon DSLRs for. Control of these cameras via their built in USB port unfortunately. Note that this cable doesnt replace the need for the DSLRs. USB port to be connected, as that is still required for computer control of the cameras settings. The serial cable only provides computerized control of the cameras shutter release. The alternative approach to computerized shutter control is the use of. AKA cable releases. Note that Canon DSLRs use one of two main types of remote switch socket. Canons consumer range of DSLRs. D, 3. 50. D, 4. 00. D, Digital Rebels, Kiss, etc, and the proprietary N3. D, 2. 0D, 3. 0D, 5. D, 1. D, 1. Ds, etc. The Canon RS 6. 0E3 manual remote switch can be used with the consumer range, and Canon RS 8. N3. manual remote switch and. TC 8. 0N3 timer controller can be used with the prosumer professional ranges. The manual remote switches are essentially useless for long exposure astrophotography. It is a good choice for people that want to travel light and avoid the use of a computer in the field. Its also a useful tool for timelapse photography. The timer controller can be converted to use with the. N3 to 2. 5mm converter cable. For astrophotography the use of a computer to control all aspects of the DSLR. It allows for complete software control and automation of exposure runs, and in particular it enables. The immediate access to the images enables you to track the progress of the ongoing exposure sequence. There are some additional minor advantages such as no storage limitions. Virtually all the DSLR astrophotos you see on this site have been made using a serial shutter control cable. An alternative approach to shutter control using the serial port is use of a. Can be used with modern laptops that generally now lack parallel ports. Can be used with standard USB to serial converters for computers with no spare. The basic circuit is a little simpler, cheaper, and easier to build than the parallel. With a USB to serial converter it can also be used to provide long distance camera. USB CAT5 type extenders such as. VPI and other similar devices. Use of a USB hub for both the USB to serial converter, and the camera USB cable. The control circuits, their schematics, and the following details are all. Please. note however that there is absolutely no warranty provided or implied, you. The Basic Circuit. This basic circuit was the initial serial port based design. Its the simplest circuit to understand and build. LED designs described further down. All of the designs discussed on this page follow a standardized. RS2. 32 serial pins and are fully software compatible. The basic circuit design is very similar to the older. DSLR control circuit, but with the addition of an extra diode. The 2. N3. 90. 4 transistor is rated to handle up to 6. V backwards across the. V, some. protection is necessary.

Connecting the serial control cable to Canon consumer range DSLRs is straightforward. Connecting the control cable to Canon prosumerprofessional DSLRs is more of a problem however. N3 type socket. One way to source an N3 connector for the control cable is to cut off the N3 plug and a short. N3 type remote switch, placing a 2. N3 cable end. and 2. This allows you to mate the N3 connector with either the serial control cable or the manual cable release. RS 8. 0N3 wiring red shutter tip in diagram, white half press ring in diagram. TC 8. 0N3 wiring red shutter, yellow half press, bare wire ground. Experience has shown that some RS 8. N3s have the above colour. Its therefore a sensible move to. Wade Calvert provided a N3 pin diagram that can help in this process. Hacked Canon TC8. N3. Perhaps the easiest way to connect to an N3 type camera is to. You can plug a 2. N3 plug into the camera. The control cable will then be able to fire the shutter on the N3 based camera. I purchased an ADIDT M1 C3 for this purpose. These are available from ebay and other sources for around. US1. 2 postage. John Deriso notes that the. Nova Photography RS8. N3 compatible Remote Switch also has an extension socket. The switch looks to be higher build quality than the ADIDT and has a locking N3 connector. Available on ebay at around 1. US2. 5 postage. As these third party remote switches are relatively cheap you could also just use them as a donor. N3 plug and have a simpler and more robust overall cabling arrangement.
