5.0 Troubleshooting
If you are experiencing problems getting the extender to work properly,
please use the following troubleshooting suggestions.
•
Make sure that all of the connections to the unit are solid. Loose
connections are the number one cause of issues.
• Check if type of serial cable (null modem and straight through) you
have connected between CNT-IP-2 and the end device is correct. TX &
RX pins are marked on the unit below each serial port. Use tables below
to confirm your serial cables selection.
•
If web interface is not working, check Network configuration (IP
address, Subnet address and Gateway address) of the unit. Contact your
network administrator if necessary.
• Each end device (i.e. projector, display) has proprietary commands and
command format based on manufacturer. Make sure commands added
to actions have correct format.
• If you still are not able to get the system working properly, contact Hall
Research support (preferably via email or the form on support page of
www.hallresearch .com) with a detailed description of the issue and the
troubleshooting steps you have taken.
Do not open or try to repair the unit yourself as this will void your warranty.
To return the extender for repair, you must contact HR Support at 714-641-
6607 or via email or web. To ship the unit back for repair, make sure to
obtain a Return Material Authorization (RMA) number.
