Setting The Mac Address - Intermatic ET9500 Configuration Manual

ET9500 Installation and Configuration Guide
2.4 Setting the MAC Address (ONLY USED for BACnet MS/TP)
• ET9500 uses the "A" bank of DIP switches (A0 – A7) to assign the MAC Address for the
ET9500.
• The default configuration is Address 3 (A0, A1 on and A2-7 off).
• I f you need a different address remove the white label (A0-7, B0-3, S0-3) to access DIP
switches.
NOTE: When setting DIP Switches, please ensure that power to the board is OFF.
• Note the following:
o Only 1 MAC address is set for ET9500 regardless of how many devices are
connected to ET9500.
o Set the MAC address of the ET9500 to a value between 1 to 127 (Master MAC
address); this allows the BEMS Front End to find ET9500 via BACnet auto
discovery.
o Note: Never set a BACnet MS/TP MAC Address of the ET9500 to a value from
128 to 255. Addresses from 128 to 255 are Slave Addresses and can not be
discovered by BEMS Front Ends that support Auto-Discovery of BACnet MS/
TP devices. This restriction does not apply to the Modbus RTU or Metasys N2.
See Figure 5 for the switch settings to select Address. Please refer to Appendix C.1

for the complete range of MAC Addresses and DIP switch settings.
