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.
Ethernet (LAN) input signal requirements
Precor recommends 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

communication protocol
The touchscreen consoles use a security token for communication to the Precor servers. The
security token is a hash string that is sent with every API call from the FE’s to the Amazon
Cloud. The security token originates after the equipment is registered at the location. The con-
sole 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 Business Suite (PBS).
All communication with Precor servers is currently done via outgoing (originating from the con-
sole) HTTPS sessions. The console utilizes NTP
2
to set its clock and for synchronization. At
no time is Precor connecting to the customers facility network to "push" any data. The console
initiates all data requests.
