DIP 1-DIP4: Controls RS485 addressing BIT 0-BIT 3.
ON: Address bit set.
OFF: Address bit NOT set.
 Addresses “1” to “15” are available using dip switch configuration.
 Each Communication Hub connected to the same RS485 bus must have a unique RS485 address.
 An address of “0” disables the EAC interface of the Communication Hub DO NOT use this configuration
for normal installations. It also sets the Communication Hub in constant pairing mode.
 See RS485 Addressing Reference on Page 9.
DIP 5: Not used.
DIP 6: Controls use of RS485 pull down resistor.
ON: 620 Ohm pull down connected /enabled.
OFF: 620 Ohm pull down disconnected /disabled.
DIP 7: Controls use of RS485 pull up resistor.
UP: 620 Ohm pull down connected /enabled.
