6.1.10 RS232 error rectification
Problem Questions for corrective action
No characters can be
received on an attached
printer. ⇒ Are the devices switched on and the connecting cables
plugged in properly?
⇒ Is the printer set to ”on-line”?
⇒ Do the baud rate, data bits and parity for the two devices have
the same setting?
⇒ Is the handshake set properly?
If everything appears ok, try to print out a report by pressing the
<REPORT> key.
No data transmission
occurs and an error
message appears in the
display of the 732 IC
Detector. ⇒ ⇒ RS error 36… …39: Receive errors.
Do the RS232 data transmission parameters of the two de-
vices have the same setting?
⇒ RS error 40 … …42: transmission errors.
Is the cable used correctly wired and plugged in?
Is the printer switched on and set to ”on-line”?
⇒ RS error 43: Data output of the 732 IC Detector blocked for
longer than 3 s by XOFF.
The received characters
are garbled. ⇒ Do the data bits and parity of the two devices have the same
setting?
⇒ Does the baud rate of the two devices have the same setting?
⇒ Is the correct printer selected?
⇒ The data transfer has been interrupted by the hardware during
a printout. Set up connections again, switch printer off then
on.
The graphics plot is not
printed out properly. Other
reports are ok. A handshake is necessary for the graphics plot.
⇒ Is your cable correctly wired? (The DTR of the printer must be
wired with the CTS of the 732 IC Detectors.)
⇒ Set the handshake on the 732 IC Detector to " HWs ". The
printer must be so configured that its DTR is set (usually with
DIP switches).
