Wireless option
Controls with the wireless option are versatile and secure, without the
need for wiring and cable conduit that is necessary for direct wired con
-
trols. The wireless controls are a good option for scoring on established
playing fields when trenching for a direct wire connection is undesirable.
Wireless also provides flexible control for indoor situations.
Trans-Lux/Fair-Play’s wireless controls uses spread-spectrum technology to
avoid interference with other electronic devices. The MP-70 and MP-50
also use direct sequence transmission, which locks onto the receiver at
start-up and sends thousands of radio signals over one radio channel to
the scoreboard. The radio signal travels over a longer range - important
for open playing fields - and the radio signal remains consistent to ensure
game clock accuracy.
Some common wireless features include the following:
• Factory-installed and tested transmitter (receiver and antenna).
• Can run synchronized operation of two or more scoreboards from one
control, operating on the same channel.
• Does not interfere with wireless LANs and personal computing devices
that use the 2.4GHz ISM band.
• Operates normally, even in the presence of cellular telephones, pagers
and transmission towers.
• Radio link receiver light indicates transmission link is operational.
• Transmission range of at least 300 feet indoors, and 1,000 feet out-
doors.
