The following explains a box-to-box connection.
1. First, transmitter (NET104A) and receiver (NET101R/R-A) need to be configured appropriately. If
the units are supposed to be operated in different subnets, a gateway IP address must be
configured. Use the alarm IP address field to address the destination. Also, the transmitter’s
video standard must be set to H.261. Enter the settings using either a terminal program or a
web browser.
You also must disable Internet proxy settings. To do so: In Internet Explorer, click the Tools
button, Internet Options, the Connections tab, and the LAN Settings button. Then remove
the check mark in the Use a proxy server box. Click OK, and then OK again.
2. Once all addresses are configured, type c in the terminal window to establish the actual
connection or program the live video receive IP and enable the live auto connect setting
through the web browser. Make sure the alarm IP address in the unit that will initiate the
connection points to the destination unit. After a few seconds, video transmission begins and
the camera scene appears on the monitor attached to the receiver.
Instead of using a terminal program for establishing a connection, you can attach a contact to
the alarm input. Make sure the alarm input is enabled.
You can use a web browser to connect to either of the two units, even during an active box-to-box
connection. This way you can make changes to the configuration and immediately see the result of
the setting (for example, when changing video quality). If you are connected to the transmitter, the
camera pictures are sent to the receiver and web browser simultaneously. There will be a short
break in the video display on the receiver monitor whenever the web browser requests a new
frame. This is especially noticeable with the Server Push feature.
Full-duplex audio can be transmitted in parallel with the video transmission in units equipped to
handle audio. To do so, you need to use the web browser to enable audio on the Audio Settings
configuration page.
Transparent data is always transmitted automatically between the two units as soon as the
connection becomes active. Data bytes entering the interface are transported to the other end
transparently. There is no flow control mechanism for the data channel. Overflowing the serial
interface will cause data loss.
To sever the connection from either end, type d in the respective terminal window (or disable the
alarm).
