4. Set the network node address on the A1620 NETWORK ADDRESS switch as
shown Table 1. It should be noted that any number of panels can be configured as
address 0. This configures the panel as a passive node. A passive node can receive
data but cannot transmit data to other network panels.
5. To enable networking, S4 switch 4 on the A1579 should be moved to the ON
position (switch 2 on the A1638 Premier AL Global Repeater motherboard). This
should be done after stand-alone panel commissioning is complete.
