If you are using a Feig reader and have everything in ClearStream properly configured, yet seem to be unable to read any tags, you should check to see if the reader is in the correct operating mode.
Within the device configuration, you can select your reader, then go to the device tab. Feig readers will have an "Operating Mode" option that lets you select between buffered read mode, notification mode and host mode. The default mode is Host Mode
The differences between the modes are outlined below:
- Host Mode – All commands are issued by ClearStream and performed on the reader in a single
call. This is the default mode.
- Buffered read mode – In Buffered read mode, the reader will store all tags it scans on the
reader itself until ClearStream requests all tags scanned. This mode is faster than Host mode,
however when a reader is stopped using the ClearStream interface, the Feig reader will continue
to scan for tags. The tags it scans won’t be sent to ClearStream until they are Started again using
the ClearStream interface.
- Notification Mode – Similar to the Buffered Read Mode, however the reader itself will initiate
the connection and remotely send the tag data back to the IP address and Port specified. This IP
and port combination should be a PC running ClearStream, and the port should be unique for
each reader configured. Make sure all Ports used are open. This mode is useful for a remote
installation of the reader where direct network access from the PC might otherwise not be
possible. The Keepalive option tells the reader to communicate home at a set interval so
ClearStream can detect a lost connection.
