CATV RF power requirements
For P62, P80, and P82 or PVS displays, there is a minimum RF input power requirement to
properly supply
CATV
1
signal to the consoles.
l
Analog video power: +5 dB to +10 dB RF power with a +40 dB minimum channel to
noise ratio (at each display).
l
Digital RF power: -5 dB to 0 dB (at each display).
For MYE displays.
l
Analog video power (at each display): - 30 dB to +20 dB RF power with a (+40 dB C/N
(Channel to Noise ratio).
l
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:
l
512Kb/s up
l
5-10Mb/s down
l
Switch Ports: 80, 123, 443
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
NTP

to set its clock and for synchronization. At no
time is Precor connecting to your network to "push" any data. The P80 initiates all data
requests.
