2 Commissioning

The Memory Card contains the entire system software for AS 488/TM. It responds with the
version ID M02.02 .
To perform an upgrade or update from diskette, an AS 488/TM memory card must be
available.
The upgrade procedure is performed offline with a PC or a programming device having a
compatible MC interface (e.g. PG740).
The update procedure is performed either from the IBS terminal (online) or from a
programming device having a compatible MC interface (e.g. PG740).

A description of the upgrade procedure is provided under heading 2.2 in this document, of
the update procedure under heading 2.3 .

Caution: The file RM3_PC1.SYS on the memory card must never be deleted or

overwritten, as this would mean that the memory card would no longer be
bootable!

If this happens nevertheless, the memory card can be restored on a
programming device with the help of the upgrade diskette (see chapter 2.2.1).

Notes:
The V.24 serial interfaces of the AS 488/TM and the PCs are non-isolated. With a distance
of more than 10m between the earthable point of the AS and the earthable point of the
PC's protective conductor an electrical isolation of the interface has to be planned.
Further electronic switches for multiplication of the PC's serial interfaces are not suitable
for the commissioning terminal because of the interruption of telegrams at any point. We
recommend the use of the integrated software switch for up to four AS interfaces.
