range error
#
Error in internal hardware test.
Inform Metrohm service.
RS error 36
RS receive error; wrong parity.
<QUIT>, set same parity for both
devices.
RS error 37
RS receive error; wrong stop bit.
<QUIT>, set same stop bit for both
devices.
RS error 38
RS-receive error; overflow (at least 1
character could not be read).
<QUIT>, set same baud rate for both
devices, restart sender.
RS error 39
RS receive error; overflow of internal
receive buffer (>82 characters).
<QUIT>.
RS error 40
RS transmission error; DSR = OFF.
Handshake unsatisfactory for more
than 1 s.
<QUIT>, check receiver (switched on
and ready?).
RS error 41
RS transmission error; DCD = ON.
Handshake unsatisfactory for more
than 1 s.
<QUIT>, check receiver (switched on
and ready?).
RS error 42
RS transmission error; CTS = OFF.
Handshake unsatisfactory for more
than 1 s.
<QUIT>, check receiver (switched on
and ready?).
RS error 43
RS transmission error; transmission
of the IC Detector interrupted with
XOFF for at least 3 s.
<QUIT> or send XON.
RS error 44
RS transmission error; the RS232
parameters for the two devices are
no longer the same.
<QUIT>, reset RS232 parameters for
both devices.
RS error 45
RS transmission error; the receive
buffer of the IC Detector contains an
incomplete string (L
F
missing), the
transmission is thus blocked.
<QUIT> or send L
F
.
RS error 60
…
89
Error in RS232 test.
<QUIT>, check connection between the
two RS232 interfaces.
