PhastLink uses a standard 10Base-T connection (i.e. Category 5 wire and RJ-45
connectors). The wire should be connected in the standard manner, as shown in
the following figure. If a consistent color code is used, wiring problems will be
minimized.
It is important that the correct pairing is observed. Transmit, Receive, and Mic need
to be on twisted pairs. Splitting pairs (e.g., using a white/green wire with a
blue/white wire for transmit) will result in increased crosstalk, and may result in
bus failure or noise on the intercom.
Connecting to a Cardframe or Hub
If a PLB-CF10 cardframe is used, a 15-port hub is built into the cardframe. The
maximum length of wire per port is 1,000 feet. Each PhastLink device has two RJ-
45 connectors to allow multiple devices to be daisy-chained on one PhastLink port.
Refer to the PLB-CF10 documentation for more detailed connection information.
The limit for each home run is 10 PhastLink devices. Extra hubs can be added to
provide additional ports.
