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 I/R 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 bet ween data sent by the
meter and the response that should have been received from the Base Unit. Possible causes:
o
Meter misalignment with the Base Unit (make sure the communication windows are
facing each other, within the distance indicated).
o
Base Unit is not powered. If power is present, one Base Unit LED should be lit. If this is
not the case, check power connections.
o
No connection to the PC. The Base Unit must be connected to the PC through a serial
cable. Check connection.
b.
KBD: This message occurs when the user presses a key during communications. 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.
NOTE:
Individual records cannot be downloaded to the PC. The entire storage content is delivered to
the PC during a link session.
