Introduction
Relay Output
Jumper Use Instructions
The many jumpers on the controller PCB allow you to perform a variety
of operations manually:
EOL 1-4: Enables the user to add End-Of-Line jumpers that improve
communication signals. Put the jumper in R position (as
shown on wiring diagram) to activate the End-of-Line
termination. (R provides a resistance termination and RC
provides resistance and condensator termination.)
SHDN: Enables you to reset or temporarily shut down the
microcontroller. This function is used mainly when system
wiring adjustments are needed (power off for safety).
Relays These jumpers let you test the relay by activating it without
J29-J32: having any effect or impact on Events.
