Issue
Trying to repair/restore a damaged Microsmart controller trunk. The last controller on the trunk was removed and thrown out before the EOL module could be removed and placed in another controller. Installing external resistors to mimic the EOL module is the only option. What are the resistance values with the EOL module?
Environment
DMS (all models)
Microsmart (all models)
Cause
Site construction/renovation removed the last controller and the EOL module was not removed before it was thrown out.
Resolution
Replacing the EOL module with external resistors is not a recommended alternative. However, in an effort to stabilize controller communications until a proper EOL is installed, here are the resistance values within the module:
It is an 8 pin module:
Across pins 1-8, 3.3 kohm resistor
Across pins 2-7, blank
Across pins 3-6, 150 ohm resistor
Across pins 4-5, 3.3 kohm resistor
All resistors are 1/4 watt, 5%
