I just wanted to post on pairing a touch panel with a Cisco TelePresence SX20. The instructions do not mention turning on SSH on the SX20 in order to pair the two devices. The fix is easy. After installing the SX20 and the touch panel using LAN (not directly connected), browse to the http interface of the SX20. Log into the SX20. The default username is admin, and no password (blank). There are some tabs at the top of the web interface. Click on configuration, system configuration, and type SSH into the search box. There will be a drop down menu for SSH (on or off, default is off). Click on the drop down menu and click on. Click on the save button. There is also a pairing setting on the TV. It is under advanced settings, under pairing. Make sure that pairing is on when trying to pair the two devices. If the touch panel does not automatically list the SX20 as a codec for pairing, there is a manual setting to type in the IP address.
Thanks,
Alex
