Peripheral issues

Touch

General information
The Touch interface panel has two methods of connection, it can be plugged directly to supported
systems or paired with a system over Ethernet. EX and MX systems are shipped as standard with the
touch panel and with these systems the touch panel plugs directly into the codec. For other codecs
(C series, SX) the Touch panel plugs into a power injector which in turn plugs into your network allow-
ing pairing over the network or in some cases directly into the Ethernet 2 interface (C90, C60, C40).
When a Touch interface connects to a codec it will check to ensure it has the correct software for that
release. if not the Touch will be upgraded to the current release and will restart.
You can find out if the video system is paired with a Touch panel from the web interface. Navigate to:
Configuration -> Peripherals.
Problems pairing Touch to system (Connecting...)
if you are having connection issues you should confirm that
•
The Touch is physically connected to the codec directly or that it is plugged into the lAN or
Ethernet 2 port of a C40, C60 or C90
•
if you are using the lAN connection and power injector, check the lED on the power supply
block to ensure it is green
•
if you are using lAN, check the switch port to ensure there is a connection lED and check
the network switch configuration
•
if connecting directly to a C40, C60 or C90 check that the second Ethernet port is set to
DirectPairing (see below)
•
Try restarting the video system
•
if the Touch is powered via the power brick, unplug it and replug to restart the Touch panel
Factory reset
if you are having persistent problems, the last resort is to factory reset the Touch panel. For information
on this, please see "Factory reset the Touch panel" on page 26.
D15029.01 Troubleshooting Guide TC6.0, April 2013.
Connect Touch to C40, C60, C90 Directly
To connect a Touch panel directly to the secondary Ethernet port on a C40 C60 or C90 codec, you
must enable this port from
Configuration -> System Configuration -> NetworkPort2
setting from Inactive to DirectPairing.
Once Direct pairing is enabled you must restart the codec to start the pairing process.
NOTE
WArNiNG
Do not connect lAN to the secondary Ethernet port. When enabled, the secondary Ethernet
port will run a DHCp server that can create conflicts with DHCp servers already present in the network.

Camera

No image seen when self-view enabled
To check the camera firstly enable self-view on the system to see if you can see your camera image.
if you cannot see anything in self-view then:
•
Ensure that the privacy cover is not closed (EX series).
•
if you are not using a built in camera check the physical cabling. Confirm that the camera is
attached to the system and to which input it is connected (C Series, SX20).
•
Check that the camera is operational. if you are not using a built in camera you can connect
the camera into a standard screen with a HDMi input to check if there is an image from the
camera (C Series, SX20).
•
Confirm that the correct input source is selected for the main video source.
•
Confirm the number of the input the camera is connected to.
•
Check in
Configuration -> Video -> General Settings -> MainVideoSource
matches the number of the input the camera is connected to. You can check the default camera
input from
Configuration ->
that the camera is using input 1 so the MainVideoSource should be set to 1.
•
in the above image you can see that the system is receiving a video signal as it displays a
signal after the words Main camera. in this case the signal being received is 1920 x 1080, 30Hz.
if there is no value here check the HDMi connection and ensure that the camera has power
(SX20, C Series). if your system has a built in camera contact support for further diagnostics.
