13.3 Terminate the end nodes of the BACnet network.
Terminate the two ends of the BACnet network line with a 120 ohm resistor between the TXRX+ and TXRX signals. The Z1000U Bypass
has a built in termination resistor that is enabled or disabled using DIP switch S1 located on the bypass control board.
Enable the termination resistor by setting DIP switch S1 to the ON position if the bypass is located at the end of a network line.
Disable the termination resistor on all bypass slaves that are not located at the network line end.
13.4 Set these Parameters
• Z3-01 = 3 (Serial Communications Protocol Select = BACNet)
• Z3-02 = Unique MAC address number (No two devices on the MS/TP BACnet network can be the same.)
• Z3-03 = Baud Rate (Set all devices on the BACnet network for the same baud rate)
• Z3-04 = 0 (No Parity)
• Z3-05 = 0 or 1 (Ignore or Alarm Only. Set time to alarm using parameter Z3-06.)
• Z3-08 and Z3-09 = BACnet Object ID number (in hexadecimal) (No two devices on the entire BACnet network (MS/TP and
BACnet/IP) may have the same BACnet Object ID number.)
13.5 Cycle Incoming Power
Z1000U Bypass main input power must be de-energized and remain off until all HOA keypad indications are extinguished. This
process stores and saves the Z3 parameter settings.
