Data Transfer
Rate {Baud Rate}
The
baud rate indicales the number of bits which can
be
trans-
ferred per second.
Peripheral devices muSt be fully able to process the selected
baud rate in order to avoid errors in data transfer. The desired
baud rate is selectab!e under the user parameters (via the
MOD key). The selected baud rate must be identical to the
baud rate of the peripheral device.

In FE mode (for the FE 401 Roppy Disk Unit from HEIDEN-
HAIN). the data transler rate is always 9600 baud regardless
of the baud rate set
via
the MOD key.
