Data Port 1
Use the Right and Left arrow keys to display the correct

EXT CAM1
for an RS-232 connection to an external
pan/tilt/zoom camera. Press the
ENTER
key to make this
selection. You will notice a change in the menu options.
Press the number
2
key
to select

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

depending on the camera you have.
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
EXT DATA
for a data channel that is closed when the
call begins and can be turned off and on by the user during
the call.
Select
HOST
if you are using a PC program such as
HyperTerminal.
Select
----
to disable the port.
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 videophone sends 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 videophone 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.
