CAUTION WHEN INSTALLING LINK DEVICES
Use caution when installing Link devices by plugging directly into AC wall
receptacles, as follows:
a) Risk of Electric Shock – Disconnect power to the receptacle before
installing or removing the unit. When removing the receptacle cover
screw, the cover may fall across plug pins or receptacle may become
displaced.
b) Use only with a duplex receptacle having a center screw.
c) Secure unit in place by receptacle cover screw.
3. V-Link Gateways (VER-5500)
The Gateway is an Ethernet-based device
that decodes and validates information from
up to 100 locations. It aggregates the
location data before sending it via Ethernet
to the Versus software.
The Gateway operates within the 2.4GHz
spectrum, receiving data from the Links via
an internal RF antenna. A connection for an
external antenna is also provided. In
general, the Gateway has a 50-foot pickup
radius that may be subject to RF attenuation.
The Gateway communicates over a two-way wireless RF channel in the 2.4GHz
spectrum, secured by an encryption algorithm. The proprietary, patented V-Link
communication protocol is designed to co-exist with other networks and will not
interfere with existing IEEE 802.1x signals (i.e. Wi-Fi, ZigBee).
V-Link Gateways typically use Ethernet (POE) to receive power, in parallel to
data, over the facility’s existing CAT-5 Ethernet infrastructure. This configuration
requires PoE 44-57 VDC 350ma over unshielded twisted-pair wiring.
Alternatively, the Gateway may be powered via the included standard 6 VDC
power supply.
