HOW TO CONFIGURE THE EXT-DSC TO USE THE SERIAL PORT
► Using the simple HTTP interface. This option is easy to confi gure, but has
some limitations. For example, it forces a daily project publishing at a spe-
cifi c timing. Moreover, the options for uploading logs are limited.
► Using iCalendar schedule fi les: This option gives you full control over the
Pull mode of the EXT-DSC, but requires an external tool to create the iCal-
endar fi les (Mozilla Sunbird for instance).
How to Confi gure the EXT-DSC to Use the Serial Port
The Gefen EXT-DSC can control external appliances using its serial port (RS-
232) interface. This type of interface is supported in particular by most profes-
sional monitors to allow switch on/off operations or image confi gurations.
To control an appliance trough the serial port interface you need the following:
► A protocol fi le for your appliance.
► Testing and debugging your protocol fi le can be done on a PC using the Se-
rial Port Protocol Studio application.
► The protocol fi le must be uploaded to the EXT-DSC and enabled.
► You need to build or purchase the serial port cable to connect your appliance
to the EXT-DSC.
► Special Gefen elements <auxCmd> need to be included into your content to
control the appliance.
For more information on controlling appliance with the serial port, you can check
the online documentation for the serial port or the RS-232 section of the FORUM.
Enabling RS-232
Enabling the RS-232 support is done using the HTTP administration interface
and the Serial Port menu as shown in the image below.
