NETWORK/DIRECT Switch
The NETWORK/DIRECT switch is used to select the connection between the
amplifier and a PSPHD. Move the switch to the appropriate position for the
connection to be used and connect the LAN port as described below:
• DIRECT: If using a direct connection to the PSPHD, connect an Ethernet
cable from the LAN port on the amplifier to the LAN port on a PSPHD.
• NETWORK: If using a network connection to the PSPHD, connect an
Ethernet cable from the LAN port on the amplifier to the local area
network. When using a network connection, the PSPHD and the amplifier
must be on the same subnet.
NOTE: Power must be cycled if the switch is moved.
