Figure 2-5 — Features of the PVS 305SA rear panel
A/V input connections
a
RGB video and audio inputs (“RGB”) — Each RGB input (inputs 1 to 4)
requires the use of two twisted pair (TP) cables, A and B. Using TP cables,
connect up to four high resolution computer video and audio sources via PVT
wallplates to these eight RJ-45 female connectors. Inputs 3 and 4 need to be
set via software to accept RGB signals (default is composite video).
C
The PoleVault
signal transmission method is specific for PVS 305SA
switchers working with PVT wallplates.
DO NOT connect to an MTP system.
DO NOT connect to an Ethernet/LAN or data transmission system.
N
The PVS 305SA is capable of receiving signals from PVT wallplates located up
to 100 feet (30m) away. The optimum distance is between 50 and 75 feet
(15 and 22 meters). Minimum distance is 15 feet (4.6 meters).
The RGB cables supplied with the PoleVault system are terminated to the
TIA/EIA T568A standard.
If other cables are used the RJ-45 termination must comply with the T568A or
T568B wiring standards (as shown in figure 2-6), and the same standard MUST
be used at both ends of the cables.

The ports on the rear of the PVS 305SA are color coded for input number and signal
type. To ensure correct cable identification and connection during installation, a
sheet of color coded cable labels is supplied. See “Labeling the A/V Inputs”, later
in this chapter, for details on how to use these labels.
