Onity HT24W / HT28 Smart Quick Reference Guide • 131
Our PMS says that Onity is not responding
The most common problem with the PMS interface is the inability to make keys.
Some of these issues relate to the PMS companies and how they code the software,
but the vast majority of these issues can be solved using common sense. If the PMS
appears to be operating normally, and the Onity system appears to be operating
normally, but the two systems are not working together, check the following items:
1. Make sure the PMS interface cable is fully connected to the back of the
Onity server. If the connector is installed at an angle, straighten it so
that all of the pins may make contact.
2. Make sure the PMS interface cable is fully connected to the PMS
terminals. If there is also an intermediate connection, make sure it is
fully connected.
3. Make sure that the Onity server is not running a process that will
temporarily halt PMS communications, such as viewing the Peripheral
Diagnostic screen.
4. Make sure that the PMS server is not running a process that will
temporarily halt communications, like a batch reporting process.
Make sure the baud rate settings for the two systems are set the same. Consult your
PMS manuals for the proper settings, and refer to the section of this manual titled
Station Configuration to set the Onity baud rate.
If the PMS connection is through Ethernet, be sure the Port Number is set properly in
both systems.
