Delay Timer 2 (assembly required)


The Delay Timer 2 is the hub of the modular system of triggers. The unit accepts input signals from other modules of the system, generates preselected time intervals, and provides instant and delayed outputs for flash and camera. Delay intervals up to 0.5 s can be generated


There are also low-voltage pulse outputs. The timeout feature is used to suppress multiple exposures. A test button is used to check operation, and instant and delayed LEDs indicate the start and stop of timing.


The Delay Timer comes in two models, the 2s and the 2x. The chart below compares features.


The DU2 kits include all the parts for the control box. Assembly is required. Experience in wiring, soldering, and troubleshooting electrical circuits is assumed. See the links to the right for more information.

What else is needed

  • In order to trigger a flash unit or wireless transceiver, select a flash trigger cable kit.
  • In order to trigger a camera shutter, select the shutter cable for your camera.

See below for options.

Flash Trigger Cable Kit (RCA type)

Hot shoe adapterThis kit is for preparing a cable to connect the flash output of a trigger to a PC jack. The kit includes a PC-type connector for the flash, an RCA plug, 3-ft of 2-conductor cable, and heat-shrink tubing. Assembly is required. If your flash unit doesn't have a PC jack but does have a hot shoe, the hot shoe adapter shown to the right can be used together with a flash trigger cable for flash triggering.


If your flash unit is one of the Vivitar models 283, 285HV, or 3700, you'll need a Vivitar PC-1 cord to connect to your flash unit. Click here for one possible source. If you're triggering your flash wirelessly or your flash unit has a 3.5mm synch jack, see this page for 3.5mm cables.

Shutter Cables


We provide shutter cables for most camera makes/models for use with our triggers. When you order a shutter cable, we include an extension cable and adapter, if needed, to convert the cable for use with the 3.5mm stereo jack on our triggers.


Select your camera make/model below and note the corresponding ID. If you don't find your model listed, compare the socket on your camera to the photos below. The photos will enlarge by clicking on them. If you are still unable to determine the type of plug that you need, please contact us. If you already have a shutter release and want to convert it for use with our triggers, this page may help.


All shutter cables, which include extension cords and adapters (if needed), are $12.95.
