REA MLV-2D Operating Manual page 90

Example:
Device:
Address: 192.168.1.12
Mask: 255.255.255.0
PC
Address: 192.168.2.13
Mask: 255.255.255.0
For operation via a gateway, configure settings as described in section 4.6.7. The
verifier's sister model, REA VeriCube, cannot be operated via a gateway.
Speed
The REA MLV-2D is equipped with a network interface that runs at a maximum speed
of 100 Mbit/s. If the REA device is connected directly to a PC whose network interface
is capable of processing a maximum of 1 Gbit/s, the speed is automatically restricted
to the maximum speed supported by both device and PC (here: 100 Mbit/s). If the
REA device and the PC are connected via an Ethernet switch with a speed of 1 Gbit/s
and the PC can, as before, process a maximum of 1 Gbit/s, then no automatic speed
throttling takes place since the Ethernet switch connects to the PC at 1 Gbit/s and the
REA MLV-2D at 100 Mbit/s. The PC therefore transmits data 10 times faster than the
speed at which the MLV-2D's network interface can handle data. Since only a minimal
volume of configuration and remote control data are sent to the REA MLV-2D, this
does not result in errors.
Connection failures
Connections can be interrupted if the REA verifier and PC are both integrated into a
corporate network. A high volume of network traffic can lead to transmission errors,
which are displayed as network errors. In this case, a second network card, intended
for the exclusive use of the REA MLV-2D, should be installed in the PC.
In some cases, problems may arise if the network adapter has been manufactured
using Realtek-branded components. In this case, a second network card may also be
of use, if it uses components from a different manufacturer.
Sensor errors
Camera modules must be checked to confirm they are properly seated. Sensor errors
may also occur if connections are unstable (see "Connection failures").
Firewall
Most computers use firewall software that provides real-time protection against the
theft of data by external parties or the installation of undesirable software by external
parties. This is an absolutely essential precaution for any computer connected to the
Internet.
The REA MLV-2D works over the network. The firewall must allow the device's data
packages to pass. In networks with very strict security policies, the firewall is often so
restrictively configured so that no communication is possible. The firewall must allow
the TCP/IP protocol and UDP broadcast.
Access rights
The REA TransWIn32 Software needs access to their installation and data folders. If
this is not the case the Verifier does not work properly.
