Example JMRI Jython Script to Interrogate QuadLN_S boards one at a time
At startup JMRI attempts to determine the state of all LocoNet Turnouts and Sensors using a process called Stationary Interrogation. On large layouts many LocoNet devices may respond to each Interrogation message, resulting in message collisions, long delays and possible lost information. QuadLN_S Version 3.1.4 firmware can be configured to support direct interrogation, where only one QuadLN_S board responds to each status request. This approach provides for reliable initialization on large layouts. The sample script individually interrogates all QuadLN_S boards in the roster between a starting address and an ending address.

Mounting Plate
QuadLN_S Mounting Plate stl file (c) 2022 N3IX Engineering
A QuadLN_S mounting plate design for 3D printing. The mounting plate has built-in standoffs for a QuadLN_S and any combination of Detector, Signaling and Driver add-on boards. Use 1/4″ or 3/8″ #4 self-tapping screws to secure the boards to the mounting plate, then attach the mounting plate to a flat surface using appropriate length #4 screws.
I typically print the mounting plates using PLA with about 25% infill. Printing takes about 3 hours on my Vyper. The board mounting hole size was tweaked to make it easy for me to start #4 screws without pre-drilling. Depending on your printer you may need to clean out the holes using a 3/16″ or 7/32″ bit to make threading the screws easier and lessen the risk of breaking a standoff.
