General information about fault location
In order to check the mechanical and electronic operability, the status
reports STA0 to STA3 should be printed out and evaluated – assuming no
obvious defects are present.

Details on the status reports can be found under the topic "Info printouts
and parameters".
Data transfer
Symptom Possible cause Solution
No data or erroneous
data

Parameters incorrect Check parameters (BAUD, PARI, SBIT,
DBIT, HAND – for serial interface only)
Cable assignment incorrect Change or replace cable (for assignment,
see interface description in the MANUAL
EASY PLUG, topic "Easy plug : General")
Incorrect handshake Set parameters (for serial interface only)
Control Choose standard character set
