Intermatic EMDS User manual

INSTALLING THE EMDS
The EMDS is a 100% digital center-off momentary switch
that looks like an ordinary wall switch and provides a famil-
iar interface to the digital bus. This switch is NOT pre-pro-
grammed and must be addressed and programmed in the
field.
Placement and Wiring
Connect to the digital lighting control bus using Cat. 5
cable with RJ45 connectors. Note all items on the bus
must be “daisy chained” and the beginning and end
items on the bus must have a terminator. If this is being
added to the bus in the middle this is not a problem. If
added at the end of the bus make sure the terminator
is removed from the previously last item to the new last
item on the bus.
If the ON LINE LED is not ashing re-check connections
and crimps.
Address and dene per instructions in the EM1400
Quick Hook-Up Guide and System and Software Start-
Up Manual. This would be dened as a 2 button switch
in the “PANEL SWITCH TYPES” Menu.
Program the switch to control the appropriate loads. The
top of the rocker is Button 1 and the bottom is button
2. For more complete details on programming switches
see the O & M Manual.
