CATV RF power requirements
For P62, P80, and P82 or PVS displays, there is a minimum RF input power requirement to
properly supply CATV
Analog video power: +5 dB to +10 dB RF power with a +40 dB minimum channel to
l
noise ratio (at each display).
Digital RF power: -5 dB to 0 dB (at each display).
l
For MYE displays.
Analog video power (at each display): - 30 dB to +20 dB RF power with a (+40 dB C/N
l
(Channel to Noise ratio).
Digital RF power (at each display): -5 dB to 0 dB.

Using an RF wall outlet
If a wall RF outlet is used to power several consoles in series for a row of equipment there is a
minimum RF power requirement at the outlet of +35 dB at +40 dB minimum channel to noise
ratio for analog video and a +25 dB for Digital video. RF signal strength of +35 dB can power
17 to 19 consoles in a single row when properly tapped out.
Internet Ethernet Requirements
It is recommend a dedicated CAT6 Ethernet feed to each equipment location.
Communication Requirements:
512Kb/s up
l
5-10Mb/s down

The P80 console uses a security token for communication to Precor servers. The security
token is a hash string that is sent with every API call from the FE's to the Amazon Cloud. It ori-
ginates after the equipment is registered at the location. The P80 issues a 'Call' which returns
the registration token and the fitness equipment URL. Every event after that uses the URL and
the token to validate/authenticate communication with the Amazon servers and Preva Busi-
ness Systems (PBS).
All communication with our servers is currently done via outgoing (originating from the con-
sole) HTTPS sessions. The P80 utilizes
time is Precor connecting to your network to "push" any data. The P80 initiates all data
requests.
