IP to Relay Command Converter for Velocity Control System
AT-VCC-RELAY-KIT
The Atlona AT-VCC-RELAY-KIT is an accessory for the Atlona Velocity™ Control System that
provides conversion between IP control commands and relay / sensor signals. This Velocity
Control Converter is very compact and can be placed anywhere a device requires control and
is not IP-capable. The VCC-RELAY-KIT is remotely powered through Power over Ethernet (PoE),
or locally from a USB power source. The primary unit installs onto any surface via a convenient
mounting dock. A simple “click” locks it into place for a secure, reliable installation. The control
port module supports DIN rail installation, and features four relay outputs plus four sensor inputs.
The inputs and outputs are both congurable for various operating modes.

Operating Notes
• The Velocity Command Converter must be on the same network as the Velocity Gateway
(AT-VGW-250) or it will be unable to sync for control.
• The AT-VCC-RELAY-KIT is PoE, to power the unit, simply plug it into a PoE compatible
network switch. If the network switch is not PoE capable, a PoE injector (purchased separately)
or USB can be used.
• All devices (AT-VCC, Velocity, AT-VTP, switchers, etc) should be set to static IPs or the
DHCP IP address reserved for each individual device.
IMPORTANT: Velocity Gateway (AT-VGW-250) must be set up before the AT-VCC-RELAYKIT is fully functional.

Relay
The relay has 4 terminals which vary in function depending on how the jumpers above the ports
are set.
NOTE: Relays can only work up to a maximum of 24V and 500 mA current.
Single Pole, Single-Throw (SPST)
Place the jumpers as shown below, this can be done to a single connector or to both to create up
to 4 independent relays.

Double Pole, Double-Throw (DPDT)
When DPDT is selected within Velocity, it will create 2 relays that work simultaneously. If one
port is opened, the other will open at the same time. The DPDT is a variant of the SPDT and the
jumpers must be placed exactly as below to work.

Sensor
The ports can be set to sense either voltage or contact closure. Contact closure will react to the
change in current, while voltage will react to voltage as low as +/- 3V or as high as +/- 24V.

IP
The AT-VCC is set to DHCP by default. If the network does not support DHCP, it will
automatically set the AT-VCC to the static IP of 192.168.1.70 after 30 seconds.
VHelp and webGUI
Velocity will nd the VCC when scan network is used, but if the VCC needs to be set up o site
rst, the software VHelp can be used.
1 Connect the AT-VCC to a network switch (PoE is best if a PoE switch is not available, a
power injector or mini USB to USB cable may be used).
2 Download VHelp from the resource tab of http://atlona.com/AT-VCC-RELAY-KIT.
3 Unzip the le to the local PC
4 Double-click the VHelp executable to open the program. Vhelp will start discovery as soon
as the program is opened.
5 Double click on the VCC (to determine the correct one, look on the bottom of the VCC for
the MAC address). The PC default browser will open to the AT-VCC webGUI.
NOTE: It is best to use the webGUI to set up the static IP only, as set up in Velocity
will override any settings selected in the VCC page of the webGUI.
6 Select Network Settings to open the IP conguration page.
7 Select the DHCP Enabled header, this will disable DHCP and allows IP settings to be edited.
8 Type in the IP details to
match the network details
of the Gateway. e.g. If the
Velocity gateway is located at
the IP of 192.168.12.15, then
the VCC should be set to an
IP within the 192.168.12.XXX
range that has not already
been used.

Installation and Set Up
NOTE: Installation of the Velocity Command Converter can only be done after the
VGW-250 has been set up. View the AT-VGW-250 Installation Guide and Velocity
Manual for instructions.
1 Connect the Relay connector into the 3.5mm port on the unit.
2 Connect the Ethernet connector into the front port of the VCC.
a If the Ethernet cable is connected to a non PoE switch, use a PoE injector (purchased
separately) or a mini USB to USB cable to a USB port on a wall port or device that
supports USB power.
3 Open any browser on the network and type in the IP address of Velocity.
4 Select the = button from the top left corner and select Sites.

8 Press the scan network button. All Atlona devices found will appear in the unassigned list.
9 Select the Add button next to the VCC. A new pop up will appear.
10 Select VCC Relay/Sensor. The AT-VCC will be added to the room.
11 Select edit on the VCC box. A new side menu will open.
