3. Service Information
3. 1. Operating Conditions
(see also Chapter 1.)
Modifications
No device already be used with CU08 in AQX system needs any modification.
The CU10 can be used in AQS system only.
Software
CU09/10 with Fast Ethernet needs the unix 970501 included in xwin–nmr2.0 or later.
The Thin Wire Ethernet (10Base2 or so called Cheapernet) is still available but can not
be run by the ”unix 970501” included in ”xwin–nmr2.0”. A later version will manage
both ethernet devices.
AQX Assembling
CU09 has to be inserted in the same slot as CU08.
All connections can be carried out as on CU08. The BNC cable of the Thin Wire Ether-
net (10Base2) should be left unconnected. 10Base2 is considered to be obsolete on CU09
and no longer available.
AQS Assembling
CU10 has to be inserted in the first slot of AQS rack.
All connections can be carried out as on CU09 with the exception of the RS485 interface
that is now available on the AQS backplane. The BNC cable of the Thin Wire Ethernet
(10Base2) should be left unconnected. 10Base2 is considered to be obsolete on CU10
and no longer available.
3. 2. Network connection
The Fast Ethernet of CU09/10 is to be connected to the first or second ethernet interface
on O2, the so called
ec0 or ec1 (see workaround).
There are two RJ45 Fast Ethernet sockets on CU09/10. They are connected inside to the
same signals but have crossed pin assignments.
The upper socket (signed ”FETH–HUB”) has to be used if CU09/10 will be connected
to an HUB. This is the normal way with twisted pair ethernet hosts.
The lower socket (signed ”FETH HOST”) has to be used to connect CU09/10 by the
same normal cable to another host (point–to–point connection).
That means, connect CU09/10 from socket ”FETH HOST” to the Host by one of the fol-
lowing accessories:
