Avoid, for example, mounting the head-end station onto a lift shaft or any other wall or floor construction that vibrates in a similar way.
r e g u l at i o n s To comply with the current EMC regulations, it is necessary to connect the lines leading in and out of the head-end station using cable terminals. When mounting the cassette in a head-end station which is installed in a 19" cabinet, make sure the connections leading in and out for the 19"...
—> The operating software of the cassette can be updated via the 9-pin D-SUB socket "RS-232" using a PC or notebook and the software "BE-Flash". You can find the current operating software on the website "www.gss.de". - 13 - PSCU 6000...

—> To transmit alarm messages, we recommend to connect the cassette to a corresponding management unit via the "RS 232" socket. Ad- ditionally the cassette can be configured using a PC or laptop and the PSW 1000 software. • The "START/SEARCH" button starts the channel search of the cassette (see chapter 6, page 22).
