The Switch Assembly provides 5 or 8 Ethernet ports, depending on the model. One of these Ethernet ports are
required to connect the Switch Assembly to a network or computer, leaving the remaining ports available for
other networked devices (1218C Electronic Tank Gauges, 1218C Wireless Client, 1218C External Input/Output
Expansion Module, 1218C Cellular Gateway, Modbus devices, etc.). Once all connections are made and devices
are all powered on, verify the connection indicators for each occupied Ethernet port are illuminated or flashing as
shown in Figures 4 and 6.
