3.0 HOW TO USE THE FEBC
3.1 Serial Input
DMX512, and CMX protocols are accepted. This input is opto-isolated.
CMX/DMX Jumper
Set jumper 2 for desired CMX (E5) or DMX (E4) operation.
Input Termination
Input termination is not normally required. However, if termination is desired, solder a 100 OHM 1/4W resistor
into R5 position.
NOTE: Termination is sometimes considered for long input control wire lengths.
Shield Wire Isolation
The shield wire is not normally passed through the FEBC product. Therefor, the receiver and transmitter shield wires
are not connected togethler. transmitter shield wire is connected to the digital ground in the FEBC.
If it is desired to connect the input shield to the output shield solder a jumper into E6.
NOTE: Connecting the input shield to the output shield is not normally required in this product's application.
This jumper should only be considered in applications where the shield wire is intended to carry a signal.
3.2 Dimmer Selection
Any dimmer may be selected as the first dimmer of a group of 4 dimmers. A selection of dimmers 510 through 512
will default to dimmer 509 (thus eliminationg wrap-around through 00). A selection of 000 will default to dimmer 001.
