VSI-Pro Max POS / Cash Register Interface
UTP CONNECTIONS APPENDIX D
AGC
The VSI-Pro Max has an AGC (Automatic Gain Control) circuit on the video input. This means that even if the video
signal is as low as 0.5 V P-P the VSI-Pro Max will automatically amplify to the proper level of 1 V P-P and insert the
cash register data into the video flawlessly. Also if for some reason the video signal is as high as 2 V P-P the VSI-Pro
Max will reduce the video signal to 1 V P-P.
With the increasing cost of RG-59U coaxial cable many installers are using the lower cost UTP (Unshielded Twisted
Pair) cable and video adpaters similar to the AVE TwistPlex line of passive and active adapters. When passive
transmitters like the AVE UTP-1500 are used at the camera end and long runs of UTP or CAT5 wire is used, the
video signal is reduced significantly by the time it reaches the VSI-Pro Max. Therefore the built in AGC circuitry of the
VSI-Pro Max allows the use of low cost passive recievers like the AVE UTP-1500 and recovers the video signal.
Network RJ45 Connector
The VSI-Pro Max has two RJ45 connectors on the side of the unit mainly for Network communications. However only
two pins of this connector is used for the networking RS-485 signals Pins 4&5. All other pins are wired in parallel so
can pass other LAN signals utilizing the same cable. When using CAT5 or CAT6 cable for 10Mbs or 100Mbs only
Pins 1&2 and 3&6 are used for the Ethernet LAN connections so the VSI-Pro Max networking signals can use Pins
4&5 without any conflict with the LAN connections. Therefore IP cameras or Internet can ride on the same cable.
Furthermore Pins 7&8 can be used to for power or the video signal utilizing the UTP-1500.

The AVE CAT5 Breakout makes all these connections simply plug and play. This device has an RJ45 connector for
the CAT5/6 wire connection of all 4 pairs. It also has an additional RJ45 for the addition of Ethernet LAN, another
RJ45 for the VSI-Pro Max Networking or Telco signals and a built in UTP-1500 for passive video transmission on the
same cable.
