Default Device Address
The default device address is formed by adding the last four HEX digits of the AP
mode HEX address minus 1 (AP Mode Hex -1) expressed as a decimal value to the
base BACnet address of the device (4,100,000). For example:
0x447E = (0x447F – 1)
17534 (Decimal) == 0x447E (Hex)
17534 + 4,100,000 = 4,117,534
Wi-Fi Security
Initially, the eZNT-Wi/eZNTW-Wi powers up in dual mode with both Host Access
Point (AP) and Station Client modes active. For security reasons, the AP Mode turns
off automatically if no activity occurs for 30 minutes. The AP mode is intended for
initial configuration of a wireless thermostat.
The Wi-Fi security mode supports WPA2-AES security. WPA2 is a common name for
the IEEE 802.11i-2004 standard. The unit supports IEEE 802.11b/g/n at 2.4 GHz.
