Discusses how to place signals around a crossover and design the logic in JMRI to operate the signals properly.

This video adds to the information for making the signal wiring connections to the SE74 and then associate appropriate control commands to each of the 16 possible signal head connections. It is an expansion/simplification of the information provided in the Digitrax SE74 Explained - 3 previously posted. If you were confused by video 3, this should clarify much of the terminology and logic associ...

The last in a 4 part series to explain how the Digitrax SE74 operates and how to install wiring as well as placing the signals on the layout and entering the logic in JMRI to make the signals react properly.

More explanation the Digitrax SE74 and how to hook up signals to be operated by the SE74 and a computer software program.

This video outlines the process for assigning specific switch numbers from the SE74 to individual turnouts drawn in a JMRI Panel Pro layout diagram. This facilitates the operation of turnouts by touch control on iPads or other touch screen devices or by using a mouse on a regular computer screen.

Explaining the installation and use of the Digitrax SE74. Clarify the confusion about how to wire and operate this complex signal and turnout motor control device.

Turnout position sensors and how to connect to JMRI

Connecting sensors for block occupancy and turnout point position to JMRI.

This explains the wiring diagram for both a block detection sensor and a turnout position sensor using the turnout motor internal switches.

This video discusses a correction to a previous video. It introduces a better method for connecting sensors to JMRI in order to monitor the actual position of the turnout points.

Which turnout machine to use? This video compares the Smail and Tortoise for use in a high technology layout where iPads and iPhones can control the layout and JMRI displays all the action on large screen TV.

Discusses how to configure turnouts in JMRI to operate in your layout.

Shows the process for getting JMRI to display your layout on TVs, iPads and iPhones.

This video introduces using technology to control and monitor trains with TV monitors, iPads and iPhones. It is an introduction to using JMRI to incorporate video displays and touch screen technology.
