The Pixel TW-283 Wireless Timer Remote Control is a relatively inexpensive wireless transmitter & receiver pair. This page is an attempt to show the essential operation in a slightly more easily readable form than the instruction sheet that comes with the devices.
Mine cost $28 on Amazon in 2018. TW-283 for Canon.
Both the transmitter and receiver take two AAA batteries. Be careful to follow the polarity designations for each battery.
To turn the transmitter or receiver on or off, hold the power button down for two seconds.
When the transmitter is on it will stay on for 30 minutes after any operation is performed. If no operation is performed in 30 minutes it will shut down.
The receiver will not turn off automatically regardless of time without operation.
The transmitter can be set to operate in:
. Single shot mode.
. Continuous (multi) shot mode.
. Bulb Mode.
. Delay Mode.
. Schedule Mode.
Move from mode to mode by using the left-arrow or right-arrow buttons.
Single and Continuous (Multi) Shooting.
For correct operation, this should match the same setting on the camera. If they do not the results may be unpredictable as shown in the table below where the results of the transmitter button are compared with the manual operation of the camera shutter button..
The shutter button on the transmitter works in the same manner as the shutter button on the camera: half a press will cause autofocus to take place (*) and then a full press will cause the shutter to operate.
In single shot mode, only one shutter operation will take place regardless of how long the transmitter button is held down.
In continuous (multi) shot mode, the camera shutter will operate continuously as long as the transmitter button is held down.
* The half-push of the button will not cause autofocus if back-button focus is selected on the camera.
Once again, the camera must be set to bulb mode.
To commence the long exposure, press the shutter button on the transmitter and release it. The receiver will send the signal to the camera to open the shutter while the screen on the transmitter will continuously display how long the camera shutter has been open. When the desired time has been reached, press the shutter button on the transmitter again.

When Delay Mode is selected, the display on the transmitter will show two numbers, one on the left side and the other on the right side. Use the left-arrow and right-arrow buttons to move between the two numbers.
In delay mode the user has the ability to set the delay between 1 and 59 seconds that will take place before the shutter opens. This is set on the right-hand number.
The left hand number sets the number of exposure signals the transmitter will send to the camera at one-second intervals once the delay time expires. This number can be between 1 and 99.
Schedule mode is the most versatile of all the modes available on the transmitter.
In this mode the user can set up an entire shoot. This shoot will comprise a number of groups of exposures (shutter presses). Every group has the same number of exposures separated by an inter-shot interval.
Each group is separated from the previous group by an inter-group interval.
The time from when the shoot starts to when the first group starts is defined by a delay.
The table below shows how all these values interact.
There are many uses for schedule mode such as time-lapse photography. Another use is its simplest form, where only one group of three shots is defined with a 2 or 3 second interval between them. This could be used for a bracketed shoot when using Speedlights. The intervals or necessary to allow the Speedlight to recharge between firings.
A section of this table is shown magnified below.
The term "Triplets" in the chart refers to the three numbers shown on the transmitter screen during a shoot. The numbers are what is shown at the beginning of each operation. The first number is the order of that operation within its container (group or shoot). This number decrements as the time passes. The third number of the triplet is the length of the operation in seconds.
