Service Manual

3.18 Level Unit – LCI Com Ports
Communication port 1 is usually used for the communica-
tion with the Work Station and port 2 is used for a Service
PC.
If there is any problem with the communication between the
Level Unit and the Work Station, check that the values are:
Protocol = 0
Baud = 19200 bps
Databits = 8 bits
Stopbits = 1 bit
Parity = 110 (where 110=none, 111=odd and
101=even).
Check also the Serial Communication-window in the con-
figuration part of the Work Station software for communica-
tion settings for the Work Station’s serial port to the Level
Unit.
Note: The information in this window should normally not be
changed. Once the system has been commissioned, the communica-
tion parameters have been checked and the communication has been
established, there is no need to change this parameters.
Note: If there is no contact between the LCI and the Work Station,
check the setting of the LCI com ports on the Backup Display on the
Level Unit. See the Operating Manual for information about the
Backup Display.
