In order to wire our Eclipse series readers for data communication
you must run the wiring in parallel.You run your wire from either the
ACC-1000 or your CN-550 (RS485 to RS232 Converter) to your first reader
then you run in parrallel from your first reader to your next reader
and so on. Do not home run the readers. Please see diagram below. You
would wire it the same way if you were going to the ACC-1000.
