EX90 touch panel not detected

[Youssef BETTAR]

Hi

I have an issue with my EX90, the touch panel is not detected can you help as to resolve this issue.

Thanks in advance.

Regards.

Unless you get a better answer (possibly Danny knows some tricks).

Is the touchpad itself powered up? What does it show? Anything suspicious in xconf/xstat/logfiles?

I would double check the cable and disconnect and connect it again,

then reboot the endpoint, possibly try to do a factory reset of the ex90,

do a software upgrade and if all that did not fix it and you have a service contract,

create a Service request or RMA for it.

Hello,

touch panel not detected is rather broad description of the issue at hand. The questions Martin has asked are very relevant, notably the "is it powered on". A directly connected touch should obtain is IP address from the EX90. The EX90 acts as a DHCP server handing out address to the touch. What is shown on the touch? Does it say "Connecting" or is it totally black? Can you check the IP address of the touch? The URL below shows the menus you can use on the touch.

See page 42.

I have a whole section on troubleshooting touch panels in presentation I did at CiscoLive London. I will send you a PDF file for your reference.

Regards,

Danny.

Hi Danny

am getting the same issues as well but was wondering if you can send me the presentation you mentioned in troubleshooting with the touch panel?

Thanks

Hello,

the slides are located at link below.

https://supportforums.cisco.com/docs/DOC-29766

There's a section on touch troubleshooting.

Also, current logfiles of codec will have information about touch panel.

Hi Youssef.

As Martin questioned:

1) Is the touch panel powering up?

2) Is there any messages on the screen? ( i.e no network cable connected )

If the panel is not booting - there is not much you can do other than to RMA it.

Hi every body

Thank you for your answers, the touch panel is connected directly to an EX90 and nothing is displayed on the screen except a line of volume level.

Regards.

[Danny De Ridder]

Hello,

that sounds promising! If the volume bar is lit, it means the touch has connected to the codec.

Can you login to the codec using ssh and user admin? E.g. ssh admin@ and then check the following :

xconfig //bright    

*c xConfiguration Cameras Camera 1 Brightness Mode: Auto

*c xConfiguration Cameras Camera 1 Brightness Level: 20

*c xConfiguration Video Output LCD 2 Brightness: 50

*c xConfiguration Video ControlPanel Brightness: 100

** end

OK

The brightness needs to be set to a certain value or the touch will be dark.

What is the value you see for Video ControlPanel when you execute the above command?

I bet it is set to 1. If so, try setting it to 100.

xConfiguration Video ControlPanel Brightness: 100

** end

OK

Or, you can use the WEB GUI and point your browser to the EX90's IP address and alter the config there.

Hopefully, that's the issue your are encountering.

Hello Danny

I have the same values except :

*c xConfiguration Cameras Camera 1 Brightness Level: 1

Thanks.

[Danny De Ridder]

OK,

so that's not the issue then.

I assumed the touch was connected. We can verify this using the following command under root access.

You first need to enable root :

systemtools rootsettings on

And the login as root and do :

[dderidde-ex90-home:~] $ netstat -p | grep endeavour

tcp        0      0 169.254.1.1:65009       endeavour.localnet:47436                                                                                ESTABLISHED 3011/sh            

tcp        0      0 169.254.1.1:65008       endeavour.localnet:33629                                                                                ESTABLISHED 3017/xinetd        

[dderidde-ex90-home:~] $

Normally there should be 2 TCP connection coming from the touch to the EX90.

Can you ping the touch from the codec?

[dderidde-ex90-home:~] $ ping 169.254.1.30

Did the codec hand out a lease to the touch?

[dderidde-ex90-home:~] $ cat /var/state/dhcp/dhcpd.leases

# The format of this file is documented in the dhcpd.leases(5) manual page.

# This lease file was written by isc-dhcp-4.1.1

server-duid "\000\001\000\001\030\236h5\000\340\014\000\214\002";

Can you get the current logfiles from your system and attach them?

Hello Danny

Thank you for your explanation, i don't have access to the codec now, i will send you the log file next Monday.

Best regards.

Hi every body

I have received a replacement touch panel, i think that is a hardware problem.

Thank you all for your support.

Best regards.
