established with the base unit. The base unit will also indicate communication
established by turning off the green LED and turning on a red LED.
3.
Press the “MANAGE DATA” button in the Delmhorst Instrument Co.
Universal Application Program. The meter will display “
Data
” on the screen
and the base unit will alternately turn on a yellow and red LED while data
transfer takes place (red indicates communication between the meter and
Base Unit, while yellow indicates communication between the base unit and
the PC). When finished, the meter will return to the Main Menu and the base
unit will, once again, turn on its green LED. For further details on managing
the meter data in the PC please refer to the HELP feature in the program.
NOTE:
The above sequence of events in initiating communication between
the PC and the meter is not mandatory. The Application Program may be
started first, or the IR Link may be selected first. The
MANAGE DATA
button
may also be pressed before communication is started between the Base Unit
and the meter. The meter, base unit and Application Program all have ample
delays built in to allow the other link components to come online in any
sequence.

TROUBLESHOOTING THE IR LINK
:
Most problems tend to occur due to the positioning of the meter relative to the
base unit. There are a few error messages that may appear on the meter’s
screen:
a.
Timeout
: This error message occurs when too much time has passed
between data sent by the meter and the response that should have been
received from the base unit. Possible causes:
•
Meter misalignment with the Base Unit (make sure the communication
windows are facing each other, within the distance indicated).
•
No connection to the PC. The Base Unit must be connected to the PC
through a USB cable. Check connection.
b.
KBD:
This message occurs when the user presses a key during
communications. Do not push any key on the meter during data transfer. The
meter interprets this as a request to escape this activity and returns to the
Main Menu. The base unit should return to a green LED
status in a few
seconds. A message should appear on the PC screen as well, indicating lost
communications.
c.
Sync:
This message occurs when data framing is lost during data
transmission. This would only happen if the wireless link becomes unreliable.
Ensure the meter and base unit are aligned and restart the session.
d.
Data E
: This message occurs when the content of a correctly framed data
packet is invalid. Again, this is an unreliable wireless link problem.
