Daktronics Venus 1500 Radio – Gen 2 - Manual (Page 12)

The J-box/signal converter and J-box/modem look very similar. The connection from the J-
box to the server radio is the same in both cases and only the input signal to the J-box will
vary.

Warning: Cat-5 cable is not recommended in this installation. The distance that
power and signal can travel may vary with the use of Cat-5 cable. If Cat-5 cable is
pulled, use one pair for the ground (pin 6) and one pair for the power (pin 1). Do not
place Cat-5 cable in this application next to Ethernet communication cables or
signal loss may occur.
Install the J-box /signal converter near the control computer. Mount the server radio at an
outdoor location in a direct line-of-sight path with the client radio. Route the signal/power
cable between the J-box and the server radio. The maximum distance between the J-box to
the server radio is 1000 feet (300 m). Refer to the system riser Drawing A-211606, and Figure
8 for more information.
