Block signalling on the GNRW phase II/III/IV.
Only spent a half day 'working on the railroad': 12 hours.
Started an engine at Seattle and ran along the mainline to check that the 'dispatchers panel' was working correctly (mainline hi lights to red).
Got out of Seattle's yard OK but had trouble at the cascade tunnel. Found that I had the two blocks and sensors backwards. That took awhile to re-arrange as, besides the physical changes, have to run the engine plus the caboose, separately, to insure the sensors are working correctly. That involves adjusting the variable 'pot' and or adding a capacitor across the sensor wires.
It appears, also, that when multiple feeds go to one block, it's best to run both feed wires through the sensor to get optimum detection.
After getting that fixed, only some capacitors and 'pot' adjustments were needed until I got to the double track leading to St. Paul and the interchange. Lots of adjustments were needed to get it working properly and I still need to get the leads to ST Paul set up.
Some software changes were also needed at this location since I changed block numbers, etc.
Tower LCC Node 48 & 3D Configuration (2) file listed below:
This lists:
detector numbers: there are 8 (one per block) per tower LCC (T LCC), I needed 3 for the 22 blocks.
block #: those I assigned to my blocks.
TLCC node: address of each TLCC. two on first board 48 and one on 2nd board (3D)
TLCC channel #: What we assigned to each block.
TLCC port: Each board takes two TLCC's so 1/2 for first board and 1 (starting over) on 2nd board.
TLCC line #: these are where each pair of sensor wires are attached. There are 4 on each side. I numbered these 1-8 to make it easier to know where to attach the sensor wires.
Output function: this is always 'no function' : Don't know why.
Input function: this is always 'active lo': this allows detection of the low voltage cabeese with lights.
Producer event 1/2: these are important: they are copied from the configuration tower LCC table 'producer column' and pasted into the sensor table, twice, and the last digit is increased by 1 (in hex) with a semi colon between them.
This is all done through JMRI software

Joe was setting this up while I was working on the block wires and sensors.
This is the initial design for triggering the correct signal at each block/turnout.
