Quick start manual
VP1801 Reader Motor Control
The VP1801 is a Velos component that is used to identify animals for feeding, weighing, milking,
heat detection etc. The VP1801 is equipped with an internal switch to support a double Ethernet
connection (web interface ready) and the existing VC3 interface. The Ethernet channel is used
for the main functionality and communication like software updates and service. An extra
communication channel is available for the VC3 systems. The function is the same as the existing
Single Feeder.
The VP1801 can be installed in a V-box.

A VP1801 can be connected in different ways:
To a shielded Ethernet cable and controlled by a switch or VPU:
When connecting the Ethernet cable, the VP1801 automatically detects TX/RX , plus and minus
connections, and switches to the correct connection.
To a shielded four wire cable and controlled by a VC3 host:
The SYNC connection is necessary for HDX ISO synchronization between other readers. For FDX
a SYNC connection is possible, but not necessary if only one antenna is used. When two
antennas are used the SYNC connection is always needed, even when FDX-only (no ISO) mode is
enabled. The switching between the two antennas uses the ISO timing.
The F SYNC connection is necessary when the distance between two antennas is ≤ 3 m. Connect
the F SYNC as shown in the picture below.

Installation steps Ethernet
Install the VP1801 in the V-box (or other box). See the manual of the relevant
equipment (feeding station, separation unit etc.) where is indicated how to install
the V-box.
Connect all required wiring. See the manual of the relevant equipment and the
manual of the required behaviour component.
Power up and check the LED indicators, see also the overview on page 9.
When the system is equipped with the auto-addressing function, the host
computer requires the address. Select “Sp > y” in the display menu of the VP1801,
see page 6. Go to Step 8.
When auto-addressing is not available, set the required address manually via “Ad”
in the display menu, see page 6.
Check the ip settings via “IP” in the display menu, see page 6. Default DHCP is on.
When DHCP must be switched off, set the required ip address settings via “IP” in
the display menu. When DHCP is switched off, the default IP address is
192.168.1.100.
Check the antenna tuning. Select “HF > H1 > tu” in the display menu to start and
enable autotune, see page 7. If external manual adjustment is used (e.g. adjustable
antenna-trafo), select “AA” in the display menu, see page 7.
Test the functioning. See manual of the behaviour component. In case of
malfunctioning the connected devices like sensors, motors, valves can be checked
with options from menu option “It”, see page 7.
Install the VP1801 in the V-box (or other box). See the manual of the relevant
equipment (feeder, separation unit etc.) where is indicated how to install the Vbox.
Connect all required wiring. See the manual of the relevant VC3 application.
Power up and check the LED indicators, see also overview on page 9.
Set the required VC3 address via “CO > SA” in the display menu, see page 8.
Select the VC3 application and other relevant VC3 settings via “CO > AP”, see page
8.
Check the antenna tuning. Select “HF > H1 > tu” in the display menu to start and
enable autotune, see page 7. If external manual adjustment is used (e.g. adjustable
antenna-trafo), select “AA” in the display menu, see page 7.
Test the functioning. See the manual of the VC3 application. In case of
malfunctioning of the connected devices like sensors, motors, valves execute a
test with options from menu option “It”, see page 7.

Connections
See the manual of the concerning behaviour component for a detailed overview of the
connections. O5 is default controlled by the identification process of the VP1801 itself, and can
be overruled by the behaviour component. If the V-box has a signal light, connect it default to
O5.
When connecting the Ethernet cable, the VP1801 automatically detects TX/RX , plus and minus
connections, and switches to the correct connection.
