key to make this
selection. You will notice a change in the menu options.

. Use the Right and
Left arrow keys to scroll through the options and select
external camera driver you require.
Select

for an application that passes data, and the data
channel is open when the call connects. This is the option to
use if you are connecting an alarm system.
Select
ADV DATA
for a data channel that uses handshaking
to ensure no data is lost.
Select
HOST
if you are using a PC program such as
HyperTerminal to view the status of the eyesite 550.

Baud Rate
Set the Baud Rate using the Right or Left arrow keys.
This field determines the data rate at which the data port
operates and varies according to equipment.
Handshaking
Select
SOFT
,
THRU
or
NONE
using the Right or Left arrow
keys.
The Handshaking field setting determines whether the data
port will use Handshaking for flow control to the local
connection.
If
SOFT
is selected, the eyesite 550 sends to X-ON and X-OFF
characters to control the flow of information over the video
call. Soft Handshaking is needed when the local connection
may be set for a baud rate which is equal to or greater than the
video connection rate, or when the equipment at the local end
may not always be able to keep up with the incoming data
transfer.
If
THRU
is selected, the unit monitors the RTS/CTS line and
transmits this line to the remote location, allowing for a pass
through of the RTS/CTS line used by NetMeeting and any
other program/device that uses these lines for handshaking.
Select
NONE
if no Handshaking is required.
