EOT Repeaters

There has been confusion and lack of information about EOT repeaters used in DP consist. If these are not set up properly it will result in comm loss or failure to ARM.


Brief Summary:


Built in=Enter EOT number

Red = Flip toggle switch to repeat and enter EOT number

Blue = Enter all Zero's/Do Not enter EOT number



First, all of the C45AH/C44ACM (refurb) 2011 and newer GE engines have no separate box and the EOT/Repeater system is built in.



To program the DP to repeat simply enter the EOT code into the screen and hit COM test. Do Not Arm (Arm head end only).


For all other AC44/AC44CTE/SD70ACE locomotives there are 2 types of repeater boxes.


First is the RED Quantum box:



The red box requires that you flip the switch at the bottom to "REPEAT". Also you will need to input the EOT number in the screen and enter. Arm the head end only, not the repeater.


The last is the BLUE Box:
