Note
Only one PHAST keypad can
be used per port, so home-
run each keypad.

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.
For optimum performance, PHAST recommends the installation of a double 120-
ohm terminator in one of the RJ-45 jacks of the last device (or the only device) in a
chain of PhastLink devices.

Building a double 120-ohm terminator:

1.
Install a 120-ohm resistor (1/4-watt or larger) between pins 1 and 2 of an RJ-45
connector.
2.
Install a 120-ohm resistor (1/4-watt or larger) between pins 7 and 8 of the same
RJ-45 connector.
